Foley Scholars 2023

Karthik Seetharama Bhat is a Ph.D. student in Human-Centered Computing and is advised by Neha Kumar. Bhat’s research explores the future of carework by studying how emerging technologies can support and augment caregiving interactions and relationships. His research examines telehealth efforts in India to understand technology adoption for formal and informal caregiving across socioeconomic, geographic, and cultural boundaries. He is designing new technologies and technology-aided workflows as probes into the potential futures of telehealth. He is also examining the role that emerging AI and data-driven technologies (like conversational agents) could play in informal care environments. He has partnered with ARMMAN—a Mumbai-based NGO that is employing mHealth technologies towards improving maternal and child health outcomes through information provision and care delivery to pregnant women and new mothers. He is also working on the design and deployment of a chatbot that can perform automated tasks that reduce burdens on community health workers who moderate a chat-based online health community for maternal and child health. This is a collaborative study with researchers at IIIT Delhi, India, and SWACH Foundation—an NGO in Haryana, India, that runs multiple WhatsApp-based online health communities for maternal and child health, serving thousands of pregnant women and new mothers from rural and urban regions of north India.

Foley Scholar Finalists 2023

Arpit Narechania is a Ph.D. student in Computer Science, advised by Alex Endert. Narechania designs mixed-initiative, guidance-enriched interfaces that facilitate visual communication of appropriate and timely guidance between users and systems, and promotes the design of new visualization tools for enhanced human-data experiences from data preparation through analysis. He also develop tools that augment visualization interfaces with the querying power of natural language. A recent team research project of his examined how misrepresentation using fertility maps could change how funds are distributed to different locales and how people perceive the state of fertility in India. This project involved 16 cartographers and GIS experts from 13 global organizations such as the World Bank, UN, NASA, CDC. His team findings revealed that even the most expert map-makers find choosing appropriate binning methods challenging; this is due to limited knowledge, lack of awareness of harmful implications of using arbitrary binning methods, and organizational protocols conflicting with cartographic principles and map-maker’s preferences. His research team invented “Resiliency”, a new “goto” binning method. As a result of this research, the World Bank invited him, Dr. Clio Andris, and Dr. Alex Endert [fellow team members] to give a talk, and the United Nations offered to integrate this new map-making method into their website.

Sachin Pendse is a Ph.D. student in Human-Centered Computing and is advised by Munmun De Choudhury and Neha Kumar. Pendse is addressing mental health challenges and the positive role that technology can play. There are diverse and effective approaches to treating mental health concerns, but the process of being diagnosed and finding care can be extremely intimidating. Individuals in distress are confronted with diverse barriers, including the stigma associated with being labeled as mentally ill, the trial-and-error process of determining the medication or forms of therapy that work best for an individual, and economic or cultural factors that limit access. Navigating the pathway to care can be an ordeal as taxing as the experience of mental illness itself. He is working to better understand where technology-mediated support may be able to reduce and eliminate mental health-related barriers. He examines the role that identity and culture play in how people experience distress, and studies people from diverse backgrounds, including people in geographically sparse areas, people with limited financial means to access care, and people from minority backgrounds. He is using a mixed methods approach to understand the role that technology-mediated mental health support systems (such as helplines, online support communities, or Google search results) play in helping connect individuals in distress with effective, culturally valid support as they journey upon a pathway to care.

Alexandra Teixeira Riggs is a Ph.D. student in Digital Media, advised by Anne Sullivan. One of Riggs’s research projects, entitled “Button Portraits: Embodying Queer History with Interactive Wearable Artifacts,” is a wearable experience that explores Atlanta’s queer history using artifacts from the Gender and Sexuality Collections at Georgia State University. The project uses archival buttons from the collection to reveal oral histories of two Southern queer activists, linking the activists’ own objects to specific audio fragments. As a case study, “Button Portraits” offers insights on how wearability, embodiment, and queer archival methods can shape the design and experience of tangible historical narratives and their ability to call for reflection on our relationships to archival materials and history. By designing tangible experiences that center around queer community, history, and identity, she hopes to continue to express, loudly and proudly, that queer and trans people have always existed and will continue to exist, and that the design of technology, importantly, must center these histories, communities, and identities.

Master's Foley Scholar 2023

Arianna Mastali is a master’s student in Human-Computer Interaction, advised by Melody Jackson. Mastali has been working on a wearable activity and gait detection monitor for sled dogs and other canine athletes, called WAG’D. During her last undergraduate semester, she discovered the field of animal-centered computing. The WAG’D device consists of an IMU and a load cell and is focused on measuring gait anomalies and pull force in order to minimize injuries within sled dog racing. Her research team conducted several interviews with mushers and veterinarians who have been a part of the Iditarod in order to learn about the most common injuries in sled dogs and the existing methods to detect them. This work has significance as it will not only help better detect injuries, but will help dog owners and veterinarians better monitor dogs in order to prevent injuries.

Master's Foley Scholar Finalist 2023

Josey Benandi is a master’s student in Human-Computer Interaction, advised by Agata Rozga. Benandi is currently working on a project called the Care Coordination Study, which is funded by the AI-CARING Institute through the National Science Foundation. This project involves conducting qualitative research in the form of semi-structured interviews with people diagnosed with Mild Cognitive Impairment and their informal caregivers, so that we may better understand how these folks manage their day-to-day activities, what challenges they face in doing so, and how they go about overcoming those challenges. The Care Coordination Study has been a joint effort between myself, Dr. Agata Rozga, Dr. Tracy Mitzner, and other students, where Josey has taken the lead role in all research activities. She is seeking to create a qualitative codebook of the findings which will serve as a guide for other researchers within AI-CARING and beyond whose work may require precedent real-world data regarding the experiences of those diagnosed with and those coordinating care for those diagnosed with Mild Cognitive Impairment. 

Foley Scholars 2022

Vedant Das Swain, Computer Science (advisors Munmun DeChoudhury and Gregory Abowd)
I'm Vedant Das Swain, a PhD candidate in Computer Science (specializing in Human-Computer Interaction) from Georgia Institute of Technology. Here I am co-advised by Prof. Munmun De Choudhury and Prof. Gregory D. Abowd. My interests lie at the intersection of ubiquitous computing and computational social science. Humans interact with technologies in many ways that are impreceptible to them. Since, computers and computing have begun to engulf people's reality, they provide a unique perspective to understand human behavior. I like to extend beyond simply context-aware systems and try to understand socially-aware systems, that can help researchers understand how humans behave in communities. In my work, I leverage devices embedded in everyday life as unobtrusive sources of behavioral data and analyze human dynamics to inform the design of interventions for improving personal health and wellbeing. In particular, I investigate approaches to improve the future of work and campus life.

Sachin Pendse, Human-Centered Computing (advisors Munmun DeChoudhury and Neha Kumar)
I’m a PhD student in Human-Centered Computing at Georgia Tech. I study the diverse ways that people express, experience, and seek care for their mental health. My research focuses around the question of how the identities we hold (such as our cultural background, our socioeconomic class, our gender identity, or our sexual orientation) have an influence on how we come to understand and express our experiences of distress, as well as what specific kinds of care we need and have access to when we aren’t feeling well. Through mixed-methods examinations of these factors, I hope to understand the role that technology can play to address the individual and structural barriers that prevent people from consistent mental health. 


Kyle Leinart, Human-Computer Interaction (advisor Jessica Roberts)
I am an MS in Human-Computer Interaction student at Georgia Tech, solving problems by crafting unique experiences. Previously, I was a software developer that worked on cutting edge technologies which used the Unity game engine to solve complex engineering problems. For every project I worked on, I saw there was a need for someone to make the vision a clear reality and to be the glue between the business, design, and engineering teams. My goal is to become that person so that I can help my team create a product which will change the world. I have multiple years of experience in engineering, data, entrepreneurship, and design. In each job, I have found myself performing some of the roles of a product manager, ensuring the delivery of high-quality and optimized products that meets customer expectations and keeping a cohesive and happy team. As a Unity developer I have been able to apply the principles of game development in projects that offer more than entertainment and helps humanity.

Upol Ehsan
Computer Science 
Advisor: Mark Riedl
Upol Ehsan cares about people first, technology second. His research around Explainable Artificial Intelligence (XAI) has a personal origin story – he was wrongfully detained at an airport due to an automated system’s error, which no one could explain or hold anyone accountable for. Combining his expertise in AI and background in Philosophy, he envisions a future where anyone, regardless of their background, is empowered to interact with AI-powered technology with dignity. Putting the human first and focusing on how our values shape the use and abuse of technology, his work has charted the visions of Human-centered Explainable AI (a sub-field of XAI). By promoting equity in the conversation around AI, he wants to ensure stakeholders who aren’t at the table do not end up on the menu.

Qiaosi (Chelsea) Wang
Human-Centered Computing 
Advisor: Ashok Goel
Qiaosi Wang’s research aims at understanding the design and impact of Artificially Intelligent (AI) agents that can blend into online human communities and facilitate interactions among community members. Taking a human-centered approach, her work offers design implications on AI agents that can mediate the social interactions among online students by catering to their current practices and challenges in building social connections. Building upon online students’ preferences and concerns in interacting with AI agents, she proposes a new design framework called “Mutual Theory of Mind” to explore humans’ and AI agents’ understanding of how they perceive each other, which drives their behaviors and expectations during interactions. She is also examining the social and ethical implications of designing Mutual Theory of Mind in human-AI interactions.

Advisors: Gregory Abowd, Thomas Ploetz
Mehrab Bin Morshed’s research is at the intersection of human-computer interaction, ubiquitous computing, and health informatics. His research goal is to leverage and expand the sensing capabilities of widely used technologies to assess the mental well-being of a variety of communities. This involves data-driven, domain-driven, and user-centered approaches to (i) rethink the use-cases of existing sensors on smart devices, (ii) extend sensing capabilities to acquire human behaviors, and (iii) leverage such behaviors to model individual mental well-being. Such an iterative strategy allows him to study the feasibility and efficacy of the designed system in real-world contexts. In this way, he makes empirical, methodological, and technical contributions to the assessments of people’s well-being.

Adriana Alvarado Garcia
Human-Centered Computing
Advisor: Christopher Le Dantec
Adriana Alvarado Garcia's research uses social media data as a proxy to understand local and situated systems of knowledge. Alvarado has partnered with national and international non-governmental organizations (NGOs) in Mexico to examine the role of organizational practices and human interpretation when NGOs use data to inform their interventions. Building on the lessons of these partnerships, Alvarado is developing tools that support NGOs to use digital traces as evidence to uncover citizens’ plurality of ways of knowing and doing in times of crisis. These tools center community perspectives and the context of data production. With her research, Alvarado aims to encourage NGOs’ practitioners to reflect on the dynamics encoded in collecting social media data and challenge the notion that data-related work is neutral.

Human-Centered Computing
Advisor: Andrea Grimes Parker
Yixuan (Janice) Zhang’s research seeks to enhance the autonomy of marginalized populations during crises through information technology. Her work examines how the design of information and technologies shapes trust and distrust among marginalized communities, and how mistrust undermines their autonomy during crises. To explore how technological systems can be designed to reduce inequity, she captures people’s interactions with technologies and the dynamics of people’s perceptions during emerging crises through surveys, interviews, observations, co-design, and user evaluations. Her research shapes the understanding of how marginalized groups interact and perceive the massive amount of information and how trust forms, develops and collapses among these groups. Her research sheds light on how technologies can mitigate informational vulnerability and help marginalized groups navigate through crises.

Ceara Byrne, Computer Science (advisors Melody Jackson and Thad Starner)
In the Animal Computer Interaction (ACI) lab, I create and study technologies that improve communication between working dogs, like service dogs, and their handlers. In particular, my research focuses on improving the outcomes of service dog training. Not all dogs that go into service dog training as puppies have the temperament to become successful assistance animals. However, it is very difficult to determine if a dog has a temperament suitable for a service animal early on in life. That is where my research comes in. In my work, I investigate how aspects of canine temperament can be detected from interactions with sensors, often placed inside of dog toys that I design and build. After running tests where dogs interact with these sensors, I develop models that use sensor data to predict the success of assistance dogs in advanced training.

Azra Ismail, Human-Centered Computing (advisor Neha Kumar)
I am the co-founder of MakerGhat, a non-profit based in Mumbai that creates safe and open makerspaces to support communities in realizing their ideas for local social, economic, and political change. Broadly, my work at Georgia Tech examines and targets social justice issues around healthcare and digital technology in the Global South. My experiences at Georgia Tech and MakerGhat have repeatedly shown me that the best people to address challenges for communities are the ones who are from these communities. I see my role as a facilitator who can foster conversations, resources, and connections, to challenge and reconfigure power structures that determine who has access and voice in the health and technology spaces (typically less for women, rural, and historically marginalized groups). As part of my research, I collaborate closely with communities to identify places for design and technology to support their existing efforts to address local challenges. I have found prior research by faculty and students at GVU to be illuminating in this regard. Their engagement with communities in Atlanta and beyond serves as an inspiration, and I am similarly fostering community ties in Delhi (India), where my research is situated.

Koustuv Saha, Computer Science (advisor Munmun De Choudhury)
My research leverages social media data that reflect online analog of offline (physically co-located) situated communities. Human behavior and wellbeing dynamics are influenced by several intrinsic and extrinsic factors in both normalcy and crisis. To make conclusive research claims from social media data, I adopt causal-inference and computational approaches drawing on machine learning, natural language analysis, and statistical modeling. Causal methods minimize the confounding factors and lead to stronger claims about cause-and-effect relationships regarding people’s reactions to certain events or environments. For example, to understand the effects of campus gun-violence events on student stress, I minimized confounds, such as stress attributable to academic, personal, relationship, environmental, and other factors in college students’ lives. Also, I propose methodologies to address some of the major challenges of social media data, such as the lack of ground-truth and the lack of social media presence altogether. For this purpose, I augment social media with multimodal data such as EMAs and passive sensing streams.


Sindhu Kiranmai Ernala, Computer Science (advisor Munmun De Choudhury)
One current research project that exemplifies my research vision is the analysis of mental health status transitions as exhibited on social media. Both social relationships and clinical care are required to improve the overall well-being of those with mental illnesses. However, current delivery of care and computational approaches to study mental health are focused either on treatment of the illness (viewing the human as a patient) or support and management of the condition (viewing the human as a support seeker). The goal of this project is to computationally study the intersection of clinical and social pathways of care for mental health.

Duri Long, Human-Centered Computing (advisor Brian Magerko)
My ongoing dissertation work aims to broaden AI literacy by exploring how to design exhibits where family groups can learn about AI in informal learning spaces. I draw on design features that have been shown to aid in quickly engaging museum visitors in active learning experiences—including embodied interaction, creative engagement, and collaboration—that I have explored and tested in my prior research on designing and evaluating public-facing installations. I also draw on a deep understanding of AI technologies that I have developed in my prior research on co-creative AI systems.

Mehrab Bin Morshed, Computer Science (advisors Gregory Abowd and Thomas Ploetz)
My research lies in the intersection of human-computer interaction, ubiquitous computing, and applied machine learning. My research goal is to leverage and expand the sensing capabilities of widely used technologies to assess well-being. One of my current research that aligns with my agenda is related to food insecurities of college students. Food insecurity refers to the idea of not being able to afford food (or healthy food) for mainly monetary reasons. I have designed a study that looks into the severity of food insecurity on a weekly level. I will also investigate how it affects the wellbeing (e.g., mental, physical, and academic) of college students. In addition, I will develop computational methods to measure levels of food insecurity passively in college students.

Daniel Schiff, Public Policy (advisor Ellen Zegura)
My research focuses on the social and policy implications of artificial intelligence. I am generally interested in social policy issues (education, health, labor), the ethics of AI, governance of AI, and science and technology policy. My work is mixed methods in nature and draws on literature in the social sciences and computing. My recent research involves an empirical study of more than 100 public sector, private sector, and non-governmental organizations that have published normative AI ethics documents (i.e., codes, frameworks, guidelines, policy strategies). Our ongoing study addresses the ethics and policy issues in these emerging documents through coding of approximately 25 ethics topics and 17 policy sectors, resulting in an original data set.


Georgianna Lin, Computer Science (advisor Thad Starner)
My current research is in head-worn displays (HWD) and how to improve their experiences in everyday life from alternating tasks like order picking to aiding those who are deaf/Deaf or hard-of-hearing. Specifically, I have studied the most optimal positioning of HWD interfaces and compared different industrial HWD for order picking, compared HWD vs mobile captioning preferences, and examined name-awareness on HWD during real-time captioning. I led two teams from project idea inception to paper submission for both order picking projects and offered guidance and ran experiments for the first captioning project before co-leading the second captioning project.


Nandita Gupta, Human-Computer Interaction (advisor Carrie Bruce)
My Master's Research project is focused on investigating accessibility and inclusion practices followed by Software Developers, UX Researchers, Designers, and Product Managers in different organizations. It intends to bring together different voices of people who work on accessibility initiatives in varied roles and will incorporate storytelling to highlight their work in different areas to inspire others to get involved within accessibility. I have worked on the Zoo Atlanta Project as a UX Researcher to enhance the zoo experience for people with vision impairments. Also, through the Aware Home and in conjunction with Tools for Life, I was part of a participatory design workshop to introduce design thinking and inclusive design at the Assistive Technology Industry Association Conference 2020.

Varnit Jain, Human-Computer Interaction (advisor Rosa Arriaga)
I have been a part of the Ubicomp Group at GVU Since my first week at Georgia Tech about 10 months ago. I have been working with Dr. Rosa Arriaga to augment Post Traumatic Stress Disorder therapy using data-driven approaches. We will  apply our data-driven approach with U.S. military veterans with PTSD. My research consists of user Experience and Development. During the first phase of research, my focus was on creating a context-aware sensing platform to help PTSD patients perform homework tasks while engaged in Prolonged Exposure (PE) therapy.

Ruth Petit-Bois, Computer Science (advisor Ashok Goel)
I am a member of the Design and Intelligence Lab (DILab) and have worked with the group since the Spring of 2019. The specific project I contributed to was the Intelligent Biologically Inspired Design (IBID) project. IBID is an interactive AI research assistant that helps scientists locate and compare articles relevant to their queries. The application makes use of several ontologies (a way to represent concepts and their relationships) that are specific to the structure, behavior, and function (actions) of biological processes or organisms. This project exemplifies my personal research vision because I have always wanted to work on software that simplifies difficult tasks for users.

Shelby Reilly, Human-Computer Interaction (advisor Bruce Walker)
A recent 2019 Report by PERF (Police Executive Research Foundation) showed that more officers died last year by suicide than in the line of duty. This statistic and similar findings drove my research with my partner on the crisis concerning Law Enforcement Officer’s Mental Health. As HCI students interested in mental health, we hoped to uncover the human components involved in this issue and to create a technical system that would combat this crisis. Our first research goal was to focus on uncovering more information about our user group (Law Enforcement Officers) including their day to day tasks, stressors, social network, and environment. During this phase, I scoured online forums, videos, and officer stories and
took notes on all information that was relevant to our research questions. Then we began to research existing systems on preventing mental health problems in order to gain an understanding of the problem space and current options available.

Foley Scholars 2019

Matthew Hong, Ph.D. student in human-centered computing and co-advised by Lauren Wilcox and Rosa Arriaga, has helped to bridge HCI and medical informatics through his work. He has developed extensive field studies to understand family management of adolescents’ chronic conditions and created and tested novel co-design approaches to engaging patients, family members, and clinicians in groundbreaking participatory design studies. Hong has drawn from design insights gathered through formative studies to create and deploy technology to help families track and manage aspects of their care in the clinic (e.g., through tools that provide lay-friendly, interactive explanations of patients’ radiology reports) at Children’s Healthcare of Atlanta. He led the first study on adolescent engagement with electronic health record data through log analyses of an actual health record system at CHOA, combining log analyses with surveys and interviews to contextualize the behavior from usage logs. Hong has recently drawn from his command of design and research methods to inform the development of a novel mobile health (mHealth) system for adolescents with chronic conditions and their family members.

Lara Martin, Ph.D. student in human-centered computing and advised by Mark Riedl, researches interactive storytelling, the question of how computers can be made to understand, generate, and tell stories in a real-time interactive setting. Her thesis argues that computers will be better partners if they can understand and engage with people in narrative terms. Martin’s 2018 AAAI paper is the first neural network based story generation paper to appear in a top tier conference. This paper preceded a growing interest in the research community in using deep neural networks and is considered the canonical baseline for newer research on neural story generation. Her second notable paper, published in IJCAI 2019, focuses on controllability of neural generation systems. The problem with neural networks is that they generate stories word by word without any clear sense of where they are going or how the story will unfold. Martin led a team of Master’s students that developed an algorithm that teaches a neural story generator how to achieve a given target goal. It is now possible to tell a neural network to generate a story that ends in a particular way. This is the first time a neural story generation has been able to produce a sequence that ends in a pre-specified goal, and the research lays the groundwork for another step forward in neural text generation.

Emily Wall, Ph.D. student in computer science and advised by Alex Endert, conducts fundamental research in mitigating cognitive biases in visual analytics. The motivation for this research came from the realization that while many data-driven decisions rely on human expertise and reasoning to make sense of the data, analysts have the potential to introduce cognitive biases during interactive analysis. This is especially critical for mixed-initiative visual analytic systems that adapt analytic models based on user feedback. When such models learn from user interaction stemming from biased user behavior, they have the potential to cause ill-informed decisions in many domains of societal importance, national security, and science. In response, Wall is designing computational models of user interaction sequences and system parameters that correspond to specific biases. Further, her work explores what systems can do to help people make less biased decisions from data analysis. This research includes fundamental advances in visual analytic techniques that balance human and computation responsibilities for data analysis.


Ceara Byrne, Ph.D. student in computer science and co-advised by Melody Jackson and Thad Starner, has been a key contributor to the FIDO (Facilitating Interactions for Dogs with Occupations) project – a research effort focused on providing technology to enable working dogs to communicate. Byrne designed affordances for wearable dog vests that allowed the dogs to summon help in a medical emergency, to support Search and Rescue, and other service dog roles. She also developed a system for handlers to communicate remotely to working dogs via vibrating motors on their vests. Byrne has been researching whether augmented dog toys, such as a ball with IMU and barometric sensors, can be used to predict whether young dogs will be successful in advanced service training. Her machine learning system predicted which dogs would fail advanced training with 88 percent accuracy. Releasing the “fail” dogs early can save $5 million a year for the team’s partner, Canine Companions for Independence, a charity that raises service dogs to give to individuals in need for no-cost.

Eshwar Chandrasekharan, Ph.D. student in computer science and advised by Eric Gilbert, is applying machine learning methods to combat abusive behavior in online communities. He has applied this machinery to both building models that will be used in production systems, as well as to study the effects of specific interventions on platforms. In recent work, he shows that building models trained on other communities’ data could make better predictions about what should be removed off-site in a separate community. The intuition was that if a post on a particular website looks a lot like content seen on 4chan’s /b/ (where almost anything is permissible), then perhaps moderators shouldn’t have such content on their sites. Chandrasekharan also led a study to understand the impact of a 2015 ban of various hate communities by Reddit. Working largely on his own with an expert in causal inference methods, Chandrasekharan was able to blend his expertise in NLP with these new methods to determine that the ban mitigated the spread of objectionable behavior to other parts of the platform. Reddit has cited the study as one reason for its various closures of other highly toxic subreddits.

Eric Corbett, Ph.D. student in digital media and advised by Christopher Le Dantec, is involved in computing research for digital civics— the intersection of approaches by smart cities to sensing and data analytics, and digital democracy’s efforts to broaden sustainable and accessible civic participation via computing and networked technologies. Using Atlanta as a testbed for deploying experimental systems, Corbett has begun to layout a framework for thinking about how trust—in technology and in institutions—can be an impediment or resource for design. His insights have resulted from fieldwork with the City of Atlanta, understanding the daily practices, expectations, and limits of how officials reach and work with city residents on everything from long-term planning and policy generation to the daily challenges of service delivery. From this fieldwork, Eric has developed a theoretically and empirically grounded understanding of how trust is developed, maintained, and used in order to do the work of governance. His findings, in turn, have established a foundation for experimental design work he is completing now and which is anchoring the work of scholars in other contexts wrestling with the same problems of how to build civic technology such that it is useful and usable for municipal officials as well as urban residents.

Ari Schlesinger, Ph.D. student in human-centered computing and co-advised by Beki Grinter and Keith Edwards, researches understanding the barriers to diversity in computing, with a focus on open-source software development. Her work addresses a timely issue as companies face increasing scrutiny about their lack of diverse workforces—and the products that this produces that often exclude various groups. While much work has focused on understanding how to increase the workforce pipeline, Schlesinger’s focus is on retention—a problem given more visibility recently—but about which open questions still remain, such as why women and minorities quit trying to contribute or participate in computing. She has also taken a look at some very sensitive topics in HCI research. One example: she undertook a major review of the CHI Conference publications to examine how the research community formulates and operationalizes constructs of race, gender, and ethnicity. Schlesinger argued that the HCI community at CHI, a major ACM conference, has some way to go in how it operationalizes people’s identity in ways that are inclusive to all the constituencies that technology can serve. In short, if HCI researchers are the advocates for building technologies that are inclusive, then they need to be very thoughtful to ensure that they include people in ways that reflect individual identities.

Brianna Tomlinson, a Ph.D. student in human-centered computing and advised by Bruce Walker, uses sound as an alternative presentation method to convey information in engaging, interactive learning experiences. Recently, she has been studying how to design auditory interfaces and created a rigorous means to evaluate those interfaces. With no existing standard approach or tools to assess auditory interfaces, Tomlinson led an effort to develop and validate a quick and effective tool (“BUZZ”) to measure performance and effectiveness, preferences, and aesthetic aspects of an auditory interface. This tool is now being used and further validated by researchers around the world. This drive for rigor has led to a new important tool with lasting impact on the entire field of auditory display design. The BUZZ scale complements Tomlinson’s large body of research, which has included helping blind students in Kenya learn math and studying how to make accessible STEM tools for U.S. schools.


Emma Logevall, MS-HCI student and advised by Ellen Zegura, has been a core member of an Institutional Transformation award under NSF’s Cultivating Cultures for Ethical STEM program. She partnered with Ph.D. student Daniel Schiff to tackle the qualitative component of the project, creating interview guides and designing a research study that would allow the team to understand the student experience in ways beyond quantitative survey instruments. Logevall invested time outside meetings to iterate on the research design with Schiff, and they each conducted pilot interviews and used their collective experience to improve the design. From the 20+ study interviews, they worked together to create a codebook and to select coding software, and then each independently coded the interviews. The NSF work is highly interdisciplinary, drawing on ethics, philosophy, engineering and computing education, and professional development literature.


Alana Pendleton, MS-HCI student and advised by Carrie Bruce, has a diverse portfolio of work to her name. Through Pursuant Health, she advocated for user-centered design in the development of the "Health Age" assessment and Diabetes Risk Test features in their interactive kiosks deployed at Walmart. She led her Research Methods course project team in exploring accessibility for online ordering. In her Masters Research Project, she is working on improving the experience of participants in the Georgia Women, Infant, Children (WIC) Program, which provides nutritional assistance for low-income mothers. Pendleton has taken the lead on managing the relationship with the WIC Research Manager at the Georgia Department of Public Health (DPH), work that has included running approval and planning meetings, and navigating the IRB processes for Georgia Tech and DPH. Her work illustrates a consistent focus on research methods and design characteristics that bring additional value to research and consumer systems.

Darsh Thakkar, MS-HCI student and advised by John Stasko, has excelled in his data visualization work. One semester-long group visualization design project involved a dataset including over 30 million checkouts from the Seattle public library. The team built a visualization system that allowed a person to browse library records and look for patterns over time, search for the histories of specific books, and learn about topic- or theme-based trends. The project illustrated a creative approach to visualizing big data and making a topic of broad interest accessible to end users who wanted to find their own insights in the data. Starting this fall, Thakkar’s MS-HCI team will gather data about past College of Computing graduate student internships, post-graduation jobs, and further graduate studies. The idea is to build a visual analytics system that exposes all this data to help current students make better decisions about their future career paths. Georgia Tech students have an abundance of internship options—as Thakkar can attest to with his recent UPS internship—and he hopes to help those who follow after him more easily navigate the intern journey.

Yuhui Zhao, MS-HCI student and co-advised by Gregory Abowd and Thad Starner, recently conducted work on BrainBraille, an effort to achieve world record brain-computer interface (BCI) texting rates using non-invasive techniques that may be appropriate for locked-in (ALS or brain-stem stroke) patients to communicate. BrainBraille has been shown to work at speeds up to 8 wpm, a speed similar to that of someone texting on a feature phone. With BrainBraille, users must tense (or, in the case of ALS patients, attempt to tense) different regions of their body (hands, feet, butt and tongue) to cause blood flow in six regions of the motor cortex, which represent the six dots of a Braille character. Using the Center for Advanced Brain Imaging's fMRI, Zhao identified up to 9 different regions that would be appropriate for BrainBraille. After testing these regions, he narrowed down the voxels that distinguish to the activations of the 6 best regions and collected several datasets. He created a novel recognition technique where letters can be performed continuously every 3 seconds (4 wpm) and be recognized with 95% accuracy without using a vocabulary or grammar (open vocabulary). By limiting the vocabulary and using a stochastic grammar, the system can achieve 91% word accuracy at 8 wpm.

Stevie Chancellor
Battling opioid addiction through computation and community

Chancellor, advised by Munmun De Choudhury, researches computational methods to understand irregular behaviors in online communities with a focus on mental health challenges like pro-eating disorder, opioid addiction, and suicidal ideation. She is currently analyzing behaviors around “deviant” recovery from opioid addiction on Reddit. As opioid abuse continues to worsen, some addicts turn to clinically unverified recovery methods to ameliorate the symptoms of withdrawal. Her team is blending computational techniques and conducting interviews to identify opioid recovery behaviors across a large group of drug subreddits and then pinpoint substances that are used for deviant recovery behaviors.

Michaelanne Dye
Developing an offline Internet in low-resource environments

A pervasive assumption says that Internet access is determined by wires or wireless signals that deliver information from a computer network and onto your hard drive in a matter of seconds. The Cuban “Offline Internet” defies this convention with its robust, human-driven, media-distribution network powered often times by simple USB drives. Dye, advised by Amy Bruckman and Neha Kumar, outlines how this network, El Paquete Semanal, is shaping the Cuban media culture and what it may mean for other low-resource environments in being able to gain Internet access.

Caitlyn Seim
Helping stroke victims gain a new path to mobility

Potentially life-altering improvements in mobility for stroke victims could be around the corner thanks to research by Foley Scholar Caitlyn Seim. Pioneering work from Thad Starner’s lab in passive haptic learning allows users to wear a motorized glove and learn new skills, like piano music or Braille, as the glove taps out vibration sequences on each finger, all while the user is occupied with other tasks such as email or driving. Seim is currently developing the tech for stroke patients to help them regain a measure of mobility in their affected limbs. Learn more about her approach and view a heart-warming video of real-life patients she is helping.


Aishwarya Agrawal, advised by Dhruv Batra
Making AIs 'see' better for image content recognition

Batra is developing the foundation for artificial intelligence systems that can ‘see’ or understand the contents of an image and communicate that information to humans in free-form natural language. It’s simple for humans to describe what’s in a photo, but computer systems have a much harder time. Agrawal and a research team have developed the Grounded Visual Question-Answering model to advance AI capabilities in describing image scenes. Applications in society are wide-ranging and could benefit households and workplaces in the near future by leveraging current voice-assisted AI technologies.

Matthew Guzdial, advised by Mark Riedl
AIs can now create games on their own

Guzdial's journey in game development and research has spanned almost a decade and two degree programs at Georgia Tech. He's now reinventing how artificially intelligent agents approach creating video games. Guzdial, advised by Mark Riedl, has developed machine-learning methods that can create Atari-era looking games and play like your classic platformers (Mario, Mega Man, etc). These are the first machine-learning algorithms capable of developing a full gaming experience without human input according to the researchers.

Miranda Parker, advised by Mark Guzdial
In the pursuit of 'CS for All,' a possible new pathway

Parker explores questions of access to computer science and researches the influences on and barriers to computing education to better inform future policy and outreach. In order to create ""Computer Science for All,"" she is seeking to understand what works and what doesn't for a multitude of groups, particularly those at schools that are characterized by high levels of low-socioeconomic, minority, or under-achieving students. Her recent research suggests an important new finding in this space: Students with higher socioeconomic status (SES) may not necessarily perform better than lower-SES students in computer science because of more CS access, but rather because of better spatial ability skills, those skills used for common tasks such as navigation, measuring distances, or for technical aptitude. Spatial abilities can be taught in the classroom at lower costs, thereby marking a possible opportunity for improved CS achievement for lower-SES students and minorities.

Ari Schlesinger, advised by Beki Grinter and Keith Edwards
Developing a mindset for building unbiased software

Software has been shown to discriminate against certain groups, Schlesinger is researching ways enterprises can operationalize strategies to support software development with fairness in mind. Her work focuses on how complex social problems become embedded in technical systems—like AI algorithms and frameworks—and what steps people can take to design computing technologies that do better. Schlesinger’s recent work shows how AI chatbots have a hard time discussing race and how they might handle race in new and improved ways.

Emily Wall, advisor Alex Endert
Visual analytics technique gives users more control over data

Wall is using visual analytics to help users make the most out of the information they have available. She and a team of researchers propose that cognitive biases influence user exploration of data in ways that are measurable through user interactions. The team, including advisor Alex Endert, developed metrics to systematically detect and quantify bias from user interactions and make users aware of bias processes throughout their analyses. One real-world application: car or home buyers may dismiss certain options based on, for example, fuel economy for cars or location for homes, but Wall's visual analytics approach can measure users' preferences based on their interactions with the data, direct users to new data points, and make that next big purchase that much easier.

Melissa Baltrusaitis
Designing tech for long-flight space travel

GVU Distinguished Master’s Student Finalist Melissa Baltrusaitis, advised by Karen Feigh, is part of a multi-stage effort to develop new communication systems for human space flight well beyond the moon where real-time communication with Earth will be limited. Her focus is the design of the display and interface for a new computing framework that allows astronauts to assess their planning options during deep space missions. The “plan display and interface” is a responsive web-app that integrates the proposed plans and allows astronauts to modify or select among a number of plans. Baltrusaitis is developing multiple interactions for the interface and considering the cognitive, social, and physical demands on astronauts while on missions.

Maria Fernanda Wong Sala
Equipping healthcare workers with better safety protocols for highly infectious diseases

GVU Distinguished Master’s Student Finalist Maria Fernanda Wong Sala, advised by Carrie Bruce, recently led a study (as part of a larger CDC project) to identify the best tools to be used as a stabilization aid for maintaining physical balance while removing Personal Protective Equipment (PPE) used by healthcare workers who are treating Ebola patients and to compare different layouts of the doffing area, where equipment is removed. Wong Sala compiled the “ideal” doffing area designs to be tested in the larger CDC study with the goal to reduce cognitive and physical load for healthcare workers and risk of accidental exposure.

Dar-Wei Chen is a Ph.D. student in Engineering Psychology and is advised by Richard Catrambone. In the Problem Solving and Educational Technology laboratory, Chen focuses his research on designing instructional materials in ways that enable students to learn in durable and generalizable ways, especially in environments where a teacher might not be available. Rapidly-improving technologies have given many people the ability to summon any facts to their electronic devices from anywhere and at any time. Chen studies the unique pedagogical challenges this presents and how it will affect learning for the next generation of students. His dissertation examines “productive failure,” the hypothesis that students will learn more effectively when allowed to struggle and fail while problem-solving on their own before receiving canonical instruction. Studying PF instructional methods, Chen is examining how students perform relative to traditional “direct instruction” methods (those in which students receive canonical instructions first before completing practice problems). Chen will carry out a study in the domain of cryptarithmetic, a STEM-like domain that students might not have pre-existing familiarity with, and then replicate the study in the Rubik's Cube domain to find out whether the effectiveness of PF might change when students are engaging with material that is not as academic in nature. Chen hypothesizes that using PF methods will necessarily activate long-term and pre-existing knowledge when students are initially thrown “into the fire” of problem-solving without instruction first. The resulting connections between the old information and the learned material will help students retain the learned material for longer periods of time.

Kayla DesPortes is a Ph.D. student in Human-Centered Computing and is advised by Betsy DiSalvo. DesPortes' research is designed to change student apathy of computer science into deep-rooted engagement in the subject. She seeks to change how computing is regarded, so that students can understand and experience its interdisciplinary capabilities and feel confident that they can be producers rather than just consumers of the technology. She is also providing opportunities for a diversity of students to experience technology through enabling them to create with computing in ways they find personally valuable. Based upon the idea that personal values have a lasting impact on life choices, DesPortes' research introduces a new approach to the field of the learning sciences called “Value-driven Learning”. This approach focuses on creating a framework that engages students in iterative design, while scaffolding the students in reflecting on and integrating their values into the educational experience. Right now she has deployed two iterations of Value-driven Learning: the MoveLab in a one-week workshop and the Day of the Dead Interactive Puppets in five learning environments ranging from middle school to graduate school. The MoveLab involved middle and high school girls creating technology enhanced dance performances with dancers and engineers. The Day of the Dead project involved participants reflecting on someone that has passed away or something they have lost, and creating a computational object to represent that person or thing. An analysis has identified the promise of Value-driven Learning for creating inclusive and equitable learning environments in computing, across demographics.

Michaelanne Dye is a Ph.D. student in Human-Centered Computing and is advised by Amy Bruckman and Neha Kumar. Dye's research aims to inform the responsible design of information-focused interventions for sustainable development. She does this by conducting work that incorporates the values of individuals at each step of the research process in order to contribute to a critical understanding of the ways users experience, appropriate, and alter information communication technologies (ICTs). This vision is at the core of Dye's dissertation research, which is focused on developing a holistic picture of internet access and use in Havana, Cuba. Up until recently, internet access in Cuba was limited to five percent of the population. In the absence of access to global networks of information, individuals have developed their own community-based, information networks. At the same time, policy in Cuba is changing and access to the internet is becoming more prevalent. Dye's work seeks to understand the particularity of each of these parts, and the bigger whole as it emerges during this time of transition. Through ethnographic research in Havana, she is exploring the ways diverse stakeholders actively and creatively stitch together multiple infrastructural commitments to co-create the “internet” in Cuba. Her work has examined how new internet access initiatives (like WiFi hotspots) and the use of social computing technologies (like Facebook) are impacting individuals in Havana and the local innovations that have emerged as a result. Building on previous and ongoing work, Dye's aim is to inform policy changes and future technological advancements in Cuba.

Tesca Fitzgerald is a Ph.D. student in Computer Science and is advised by Ashok Goel and Andrea Thomaz. Fitzgerald is preparing now for a future where interactive robots are a part of everyday living, and she is doing so by designing robots to adapt to unpredictable environments in a similar manner as humans. Robot-learning algorithms do not exhibit the same type of creative problem-solving abilities as human learners. Even when an unfamiliar problem is related to one that it has previously encountered, a robot learner is unable to adapt the previous solutions to address the current scenario. Fitzgerald is researching how humans reason and acquire skills in order to transfer that knowledge to robot learners. Her research vision includes the goal of enabling robots to adapt to uncertainty in human environments and interact more closely with humans. By evaluating current theories of human cognition on a robotic platform that is capable of real-world action, perception, and interaction, Fitzgerald's research contributes to the communities of both cognitive science and human-robot interaction. Using the human cognition trait of adaptability, Fitzgerald is enabling a robot to (1) learn from a single demonstration of a task, and (2) seek assistance from a human teacher in order to repeat the task in a new environment. Fitzgerald has proposed a method that allows a robot to store demonstrations of tasks as individual experiences in memory, later recalling and adapting the most relevant experience to address a new problem. The goal is to use a case-based approach to enable task learning and adaptation using interactions across a range of scenarios.

Matthew Guzdial is a Ph.D. student in Computer Science and is advised by Mark Riedl. Guzdial's research focuses on creative machine learning (ML) and stems in part from his perception of the failings in modern ML systems, which are able to replicate existing tasks, but are unable to generate classes that haven't been seen before. He seeks to discover creative solutions via machine learning, what he considers as one of the most pressing problems in the field and one that has great potential for broader impact. Guzdial's current research project focuses on automatic game generation trained on gameplay video. A video game represents a simplified version of reality with a consistent structure and an underlying physics system. The nature of physics-based games allows people to anticipate techniques developed in this research project that can be adapted or expanded to more and more complex domains such as scientific ideation and art generation. Guzdial makes use of novel machine learning techniques to model spatial and design elements and gameplay actions from gameplay video. Inspired by research in the graphics field, he developed a process based on automatic categorization to learn a model of level design. He's also tackled automated game understanding, which represents a new artificial intelligence challenge. This work resulted in Guzdial's AI being able to essentially “clone” a game engine from gameplay video and also use an AI agent to play through the game using the cloned engine. Guzdial is currently combining these various breakthroughs to achieve full automatic game generation.

Tom Jenkins is a Ph.D. student in Digital Media and is advised by Carl DiSalvo. For his dissertation, Jenkins is creating a design research project that uses an ecological approach to develop speculative Internet of Things devices for domestic outliers. This is an example of using research through design to explore designing for alternative social configurations and to understand the role technology might play in sustaining those arrangements. In particular, Jenkins is interested in how Internet of Things might operate as a technical practice and a system of objects inside of cohousing communities. Cohousing is an intentional community designed to operate like a village in an urban environment. Residents know their neighbors, own their own homes, and share ownership of a larger common house as well as the property that the community sits on. A “smart home” for cohousing provides a way to think about domestic IoT in a new way: it operates across multiple residences, but only one home. Jenkins' project explores what a social covenant might look like for IoT objects, platforms, or APIs in this environment. This research activity in cohousing offers a vantage point to critique contemporary IoT practices as well as provide a venue to design and build Internet of Things technologies from an ecological perspective. Design valences unique to cohousing, such as ideas of where the boundaries of “home” are, or what counts as public and private space, or how groups of more than 40 people could share technologies in their homes begin to reframe what future IoT systems might be like.

Miranda Parker is a Ph.D. student in Human-Centered Computing and is advised by Mark Guzdial. Parker's dissertation work explores the “intervening” variables between socioeconomic status (SES) and Computer Science (CS) achievement. Understanding more about the relationships among these variables could lead to a better understanding of the state of equity or inequity in computer science classrooms. Parker posits that SES could affect certain variables that in turn affect CS achievement. These intervening variables could be access to computing opportunities, perceptions of computer science, encouragement to pursue computer science, availability of toys that develop spatial reasoning skills, or a myriad of other variables that then give a student a better chance at achieving success in computer science. Parker is researching what the primary intervening variables are so that interventions can be made that improve those variables in order to give students a better opportunity to learn computer science. In a pilot study, she administered surveys to undergraduate students at Georgia Tech in their first computing course. Preliminary results show relationships between certain variables, but the impact of SES on CS achievement is hard to determine since students at Georgia Tech are fairly privileged, coming from medium- to high- SES, according to the study. Due to the lack of variance in the data set, Parker is expanding the study population to more institutions. The next steps focus on growing the results from the pilot study through qualitative methods, followed by a large-scale deployment of revised surveys to better quantify the relationship between the intervening variables, SES, and CS achievement.

Umashanthi Pavalanathan is a Ph.D. student in Computer Science and is advised by Jacob Eisenstein. Pavalanathan's research includes studying factors that are shaping contemporary online writing, which is becoming increasingly distinct from other forms of written language. Such factors include the need to convey varied social meanings in online interpersonal interactions and the affordances made possible by technology-mediated channels. Pavalanathan's thesis project investigates this interplay through a series of large-scale studies of linguistic style variation in online writing using computational techniques from machine learning, natural language processing, and statistics, and theoretical constructs from sociolinguistics. Understanding the social dimensions of linguistic style variation in online writing has important consequences for the design of language technology and social computing systems, and beyond. Pavalanathan's thesis work broadly fits in the emerging research discipline called computational sociolinguistics, which integrates aspects of sociolinguistics and computer science in studying the relation between language and society from a computational perspective. The project focuses on five broad research questions related to the social aspects of linguistic style variation in online writing and is designed to advance the understanding of how individuals utilize the affordances in online social platforms and shift style to achieve varied social goals. Broadly, this type of computational sociolinguistics work will be a key towards creating socio-culturally aware artificial intelligence and socio-technical systems. Although this area is still new compared to other computational social science areas, there is an escalating interest in computational sociolinguistics and it puts Pavalanathan in a unique position to contribute to challenging work in an emerging interdisciplinary research area.

Vedant Das Swain is a MS-HCI student and is advised by Gregory Abowd. Das Swain is part of the CampusLife Project, a large scale multi-university project that started as the StudentLife Project in Dartmouth. The motivation behind the effort is to determine if mental health and academic performance could be correlated, or even predicted, through a student's digital footprint. Contextual data from students was captured through their interactions with mobile and wearable technology, social media and the environment itself in a month-long study. Das Swain is responsible for exploring, analyzing and testing the methods of acquiring the relevant type of experiential and contextual data specifically for large scale in-situ studies that are conducted remotely. His focus is on designing and validating methods that reliably and accurately obtain (and quantify) the markers that help identify the mental/emotional state of an individual; this includes mood, stress, self-esteem, etc. During the initial phase of his work, Das Swain navigated through the intricacies of polling various sensor data from a regular smartphone, ensuring the optimal use of smartphone resources to enable researchers to get the data they want without disrupting the daily phone usage of participants. He also is looking at the fundamental issue of how a participant's self-reported data translates to his or her mental state. Das Swain is focused on learning how to harness present day computing capabilities and everyday interactions to quantify the mental health of an individual better and affect positive behavior change.

Kantwon Lamount Rogers is a MS-HCI student and is advised by Mark Guzdial. With computing a constant in daily life, Lamount Rogers sees an opportunity and need for people to be creators, not just consumers, of computing tech. Equipping people to learn computer science has had middling results, with low completion rates for massively open online courses (MOOCs) in the subject and little financial incentive for people who know computer science to teach it. Lamount Rogers' current research project, interactive electronic books (eBooks), aims to change this trend by producing higher completion rates than MOOCs and facilitating improved learning. The eBooks are designed to educate instructors who have no prior computer science knowledge and equip them with the content and pedagogical understanding needed to teach other students. Lamount Rogers' role in the project is analyzing log files of users to gain insight on how people are currently using the eBook and how it can be improved in the future. Most recently, teacher and student versions of an eBook were created for the College Board's Advanced Placement Computer Science Principles exam. A log file analysis by Lamount Rogers made design recommendations for creating different AP CS exam eBooks for novice (students) and expert (teachers) learners based on his findings that the two populations use the books and learn information differently. His personal research vision is to improve the participation and success of minority students in computer science and STEM. Teachers who work in school districts that cater to black and hispanic students often lack computer science knowledge and he hopes this project can offer opportunities to affect change in these districts.

Morgan Orangi is a MS-HCI student and is advised by Carl DiSalvo. Orangi's personal research vision is one that encompasses community-building through technology. She desires to empower unique communities by introducing and integrating technology that enhances their sense of identity and methods of communication while also bringing awareness of these communities to an external audience. One project with Atlanta's Proctor Creek Stewardship Council resulted in a simulation that showed how stream pollution negatively affects Atlanta residents in low-income neighborhoods along urban streams. Another of her projects aims to enhance communication within and outside of Native American reservations through white space-enabled technologies. One goal is to expand internet access and optimize internet use in remote Native American communities, as well as understand how Native Americans produce content. As with many minority groups, Native Americans are under-represented and mis-represented in the media. With internet access, they have the opportunity to replace the current narrative with authentic depictions. Orangi's is seeking to determine what type of information the reservation residents consume, how they do so and their preference for sharing. These findings can then inform the design of a system or platform for their use. Orangi hopes to add to the research literature through surveys, interviews, diary studies, and participatory design activities with reservation residents. Existing research on reservations and new media has revealed the power of and gravitation towards social networking sites for community building and also revealed the importance of connecting physical and digital environments.

Anandghan Waghmare is a MS-HCI student and is advised by Gregory Abowd. Waghmare envisions researching and designing new techniques for computer interaction that would better connect the physical world to the digital world and augment human abilities. By designing these systems to be always available, listening and analyzing the user's environment, they are more aware of the user's actions, and the interactions become serendipitous. Waghmare's work on SoundTrak and FingerSound are examples of this concept. SoundTrak augments any object to create a 3D interaction space around it with the use of microphones and a speaker. By wearing a ring mounted with a tiny speaker, the user can interact with any surface augmented with microphones which makes the interaction space larger and allows for more novel interactions. Another project, FingerSound, is a ring which tracks the user's finger while using the palm as a touch pad. FingerSound uses a ring on the thumb to detect unistroke gestures made against the palm. Input can be started virtually at any time and in any position without requiring the visual attention of the user to select each letter. Similarly, command gestures can be made without the need to look at the device or causing the user to feel around the physical environment blindly searching for an interface device. FingerSound allows all 26 letters and digits to be written by grazing the thumb across the fingers. Putting these technologies around or on the body allows for intuitive interaction between the body and the digital world and advances Waghmare's research vision of omnipresent computing.

Mariam Asad is a Ph.D. student in Digital Media and is advised by Chris Le Dantec. Her work poses the question: “What would digital tools look like if they were designed for the values and goals of social justice communities?” Digitally supported advocacy, in its current form, might use a tool like Facebook to identify online spaces relevant to community residents (e.g. a neighborhood Facebook group), then promote a particular issue, like inviting them to an event (e.g. a canvassing training session) or asking them to 'like' a page (e.g. of an advocacy group). These mechanisms ask advocates to adjust their existing practices such that they can only be done while simultaneously supporting the goals of the corporation. The digital advocacy toolkit will include multiple levels of interactions to accommodate different kinds of social relationships, rather than basing online interactions on a single social relationship (i.e. a friendship). In addition to impacting local communities, Asad's project is also directly informed by them: she have conducted four years of ethnographic work with local Atlanta communities who do work on systemic social issues. This work spans multiple issues: Occupy Our Homes Atlanta is a housing justice group concerned with more equitable and sustainable housing and lending practices; Rise Up Georgia is a racial and economic justice group committed to empowering communities to be more politically engaged; and Sopo Bikes is a bike cooperative that encourages cyclists to learn to fix their own bikes.

Maia Jacobs is a Ph.D. student in Human-Centered Computing and is advised by Beth Mynatt. Maia Jacobs explores how cancer affects many aspects of patients' daily lives and she is developing computational tools to help better manage the chronic illness. Cancer patients must manage a vast number of responsibilities placed on them after a cancer diagnosis, such as finding information about their diagnosis and treatment options, making treatment decisions, managing the additional financial burden, and coping with physical and emotional impacts of the disease. Without proper management, health outcomes and survival rates for cancer patients is impacted negatively. Jacobs is developing and assessing MyPath, a mobile application that offers personal assistance to breast cancer patients, recognizing that each journey is unique and constantly changing. The application provides patients with resources that are tailored to their specific needs. The application continuously adapts, updating the resource recommendations as patients' progress through treatment and their needs and goals change. This work is motivated by the fact that an overwhelming number of resources exist for cancer patients, yet finding trusted tools to support one's specific needs can be a difficult task that further compounds the responsibilities placed on individuals.

Clint Zeagler is a Ph.D. student in Human-Centered Computing and is advised by Melody Jackson. He is a designer and researcher of wearable technology and interested in how to create wearable technology that is both usable and useful. Making wearable technology usable involves empirical usability studies to show how a person might interact with technology on the body. Zeagler's previous work in textile based on-body interfaces is an example of the types of usability studies he has overseen. “Is it Gropable” was one such study about how well a person could interact with capacitive sensitive raised embroidered interfaces without visual attention. Other usability and technical material studies followed developing new textile interactions and testing the limitations of manufacturing materials and process. Building on the “Is it Gropable” study, Zeagler is currently developing a user study to test the combination of haptic stimulation with capacitive sensitive embroidery in the hopes of creating interfaces that use the body's proprioception more effectively, thus enabling easier use of wearable technology without visual attention.

Stevie Chancellor is a Ph.D. student in Human-Centered Computing and is advised by Munmun De Choudhury. Chancellor studies mental wellness communities on social media platforms, where contentious interactions characterize some of the online discourse. Users in these communities are often seeking support and help; however, others promote dangerous lifestyle choices to cope with mental wellness challenges, like deliberate self-­injury or disordered eating behaviors. As a doctoral student, Chancellor's research goal is to better understand these signals of mental wellness and develop automated computational approaches to understanding behavioral cues of risky communities from social media data. Her current project explores a small segment of this goal: to build a system to detect these behavioral cues on Tumblr data. Since starting at Georgia Tech, her research has focused on assessing the health and well­being of pro­eating disorder (pro­ED) communities, a group that believes that eating disorders are an acceptable alternative lifestyle rather than a dangerous mental illness. Her projects and papers have examined community wellness after content moderation, trajectories of recovery after pro­ED participation, and measuring mental illness severity.

Michealanne Dye is a Ph.D. student in Human-Centered Computing and is advised by Amy Bruckman and Neha Kumar. Dye's research vision is one that aims to work alongside individuals in order to conduct work that incorporates their values and perspectives at each step of the process and illuminates issues that others have left unexplored. Currently, she is conducting a longitudinal study with Cuban nationals, exploring how increased access to online social networks affects the culture, perspectives, and relationships of this highly educated, yet historically isolated population. She has conducted in­-depth interviews and online observations with participants from Cuba to explore access limitations, the activities they do online, and what Internet access means to them. Findings suggest that access limitations and slow network speeds greatly restrict Cubans' Internet use. Based on these findings and through a human­centered design process, Dye has built a crowdsourced information retrieval system (“Cuba Intercambio”) to help meet the information needs of her participants. She is continuing to work alongside participants in order to shape research around their values and assist in impacting positive results for the island population, either through design implications or informing the practices of companies that are hoping to engage more directly with Cuba.

Tesca Fitzgerald is a Ph.D. student in Computer Science and is advised by Ashok Goel and Andrea Thomaz. Her research interests lie at the intersection of cognitive science and human­-robot interaction. Fitzgerald is drawn to the complexity of human cognition and human decision­-making, and how they can inspire new research developments in artificial intelligence. One such application of cognitively­-inspired systems is in robotics; as robots become more commonplace, it will be necessary for robots to process their environment and solve problems with human­-level ability. Fitzgerald is inspired by imitation learning in human cognition and seeks to enable imitation for a robotic agent such that, when provided with a single demonstration for completing a task, it can reuse the demonstration to address a related environment that differs in features such as the location, size, or appearance of objects. This is an example of “case­-based” reasoning, which takes an existing, cognitively­-inspired account for storing and reusing experiences individually in memory before addressing a new, unfamiliar problem. Fitzgerald adapts this method for use in imitation learning by having the robot store demonstrations of tasks as individual experiences in memory, the most relevant of which can be recalled to address a new problem.

Tom Jenkins is a Ph.D. student in Digital Media and is advised by Carl DiSalvo. Jenkins applies research through design with a focus on electronic artifacts. Digital media technologies afford the creation of electronic prototypes that can materialize rhetoric, creating functionality that emphasize un-­ and under­-scrutinized issues of practice by producing alternative systems that question assumptions around what values can should be built into devices. Jenkins is currently working on speculative design projects that probe the Internet of Things as it relates to alternative living situations, and in particular to cohousing communities. His thesis work provides a theoretical foundation for ecological design in order to create novel and useful design objects. It describes and classifies the contemporary Internet of Things in order to provide a springboard for design prototyping.

Matthew Miller is a Ph.D. student in Aerospace Engineering and is advised by Karen Feigh. Miller's primary research goal is to develop and build a decision-support system (DSS) for use by astronauts who are working in environments where real-time communication is not possible, such as future missions to Mars. As NASA extends human presence into deep space, the time delay associated with communication relays between the flight crew and support crew will cause a shift from a real-time to an asynchronous communication environment. Asynchronous communication has been identified as an operational issue that must be addressed to ensure success for future space missions. Miller is identifying constraints in contemporary extravehicular activity (EVA) systems and defining the necessary requirements for a DSS to support an asynchronous EVA environment. This will allow him to build and test a DSS prototype and demonstrate his approach to a design framework that includes a human-system perspective for EVA missions.

GVU Distinguished Master's Student 2016

Samyukta Sherugar is a master's student in Human-Computer Interaction and is advised by Neha Kumar. Sherugar's research focuses on Information and Communication Technologies and Development (ICTD), and one of her projects involved working with an NGO in the Indian state of Gujarat to build community support for people with HIV/AIDS. While overseas, Sherugar helped the NGO design methods to increase the number of HIV people it could help. Shereugar explored the knowledge-sharing and technology practices of the outreach workers in order to quickly prototype possible design solutions and get feedback on what worked best. The experience in ethnographic research has made Sherugar a better researcher, she says, and also given her first-hand exposure to challenges and best practices in ICTD work.

GVU Distinguished Master's Student Award Finalists 2016

Yunnuo Cheng is a master's student in Human-Computer Interaction and is advised by Gregory Abowd. Cheng worked with Ph.D. student Caleb Southern on a project for driving behavior change, which aims to inform people about real driving cost by connecting an app built in the Georgia Tech Ubicomp Lab to the car's sensors. The project gauges how people might change their perception about their driving cost beyond fuel, such as ownership, insurance, and maintenance. The first round of the study focused on mindset-changing, and the next will study behavior change and its social impact. Cheng contributed on the user research part of the project, including literature review, experiment design, survey and interview design, data analysis plan design, and the pilot study

Aditi Dhar is a master's student in Human-Computer Interaction and is advised by Beth Mynatt. For Dhar, it is essential to do work that has the potential to impact communities in meaningful ways. In one project, she is involved in exploring the space of personal safety across borders and genders and ascertaining whether the proposed design intervention (a wearable device) is a probable solution. In other work, she is designing a tool that will make a significant difference for breast cancer patients and improve their quality of life. The project helps make the patients' treatment less overwhelming by building on their self- efficacy and empowering them with resources they need. Dhar is the UX designer on the project, which envisions aiding the entire journey of a breast cancer patient – from the very day of diagnosis up to survivorship.

Sarthak Ghosh is a master's student in Human-Computer Interaction and is advised by Gregory Abowd. His research looks into the assistive nature of wearable computing, its unique attribute of being “always on,” and how to design wearables for social acceptance. Ghosh is investigating how accessible design can be integrated into the ways in which we interact with wearable devices. His current work is the development of new interaction techniques for smartwatches. “Whoosh” interaction tackles both the problems of touch and speech input, by allowing users to interact with non­-speech acoustic cues. It supports touchless interactions on the smartwatch that are quick, ecological and unobtrusive. Non­-speech vocal cues are also incorporated and are useful for people with speech impairment and for people with low hand­-dexterity and coordination. The “Whoosh” techniques are a step toward Universal Interaction­ Design for wearables and one that Ghosh hopes will make the technology move toward the mainstream.

Foley Scholars 2015

Barbara Ericson is a Ph.D. Candidate in Human-Centered Computing and is advised by Jim Foley. Ericson is helping to solve the challenge of how to prepare teachers to teach Advanced Placement Computer Science in order to increase computing proficiency among high schoolers. She is exploring using ebooks with reading groups to improve completion rates for those instructors teaching introductory computer science. Her work also explores applying findings from educational psychology to create interactive features that should improve learning outcomes. Ericson's focus is on Parsons problems, which are a type of low cognitive load practice problem and provide code segments that must be arranged in the correct order with the correct indention. Research on Parsons problems suggests that they might be a more effective and efficient learning approach than writing the equivalent code. She is seeking to develop adaptive Parsons problems, where the level of difficulty is adjusted based on user performance. Parsons problems are popular among users and creating new adaptive Parsons problems could have a substantial impact in teaching coding. 

Tanushree Mitra is a Ph.D. Candidate in Computer Science and is advised by Eric Gilbert. Mitra's research agenda seeks to understand social media credibility, its implications in everyday life and the potential damaging effects of misinformation on these channels. Her most recent work is in building an iterative framework for tracking the credibility of social media information as it spreads. Prior work in this domain has primarily studied historically reported cases of rumors and lacks an understanding of how credibility evolves in real time. Her project goes beyond the “post-hoc analysis of popular rumors” and combines machine and human computation in an efficient way to track both less well-known and widespread instances of newsworthy content in real time. This is followed by crowd-sourcing credibility assessments of the information. Running the computing framework on Twitter, it has generated a corpus (CREDBANK) with newsworthy topics, their associated tweets and corresponding credibility scores. The next goal is to design prediction algorithms - an algorithm which can reasonably assess the credibility of an event. Mitra envisions her findings being able to inform the design of innovative tools that can tackle the economic and social risks associated with misinformation in social media. 

Jessica Pater is a Ph.D. Student in Human-Centered Computing advised by Beth Mynatt. Pater is examining the role and impact social media plays on self-injury behaviors, specifically eating disorders. Over a period of seven years, she has worked with adolescents and teens, developing an understanding of how and why they use technology and then translating that knowledge back into educational outreach for educators and parents. During this extended contact with teens and adolescents from the metro Atlanta area, she began uncovering harmful and powerful ways that teens use social media platforms to facilitate risky and questionable behavior. The current instantiation of diagnostic and screening tools for eating disorders and self-injury behaviors do not take into consideration the activities of an individual online, where negative reinforcements can be found. Pater's goal is to work with leading eating disorder clinicians to help inform the development of tools that better capture and incorporate these critical connections in online activity and eating disorders. Establishing this clinical connection has already begun with discussions with Children's Healthcare of Atlanta as well as the Renfrew Center's Atlanta clinic, a national leader in eating disorder treatment and recovery. 

New for 2015-16, the GVU Distinguished Master's Student award is given to an MS student actively involved in a GVU-related research project. 

Monet Spells, the first recipient of the award, is a MS student in Human-Computer Interaction and is advised by Betsy DiSalvo. Her personal research vision is to create pathways for other women of color to feel validated in the tech and computing space. She found an opportunity to extend this passion through an educational technology project called the MoveLab with Ph.D. HCC student Kayla DesPortes and DiSalvo in the Culture and Technology Lab. Spells planned the workshop activities, identified the qualitative research evaluation protocols, executed the workshop, and evaluated the workshop data. The MoveLab was a five-day STEAM workshop investigating a community of learners as they embarked on a STEAM endeavor to create a technology-enhanced dance performance. The workshop participants included African American and Hispanic teenage girls in middle-school and high-school, dancers, choreographers, computer scientists, and engineers collaborating to develop the performance. Participants were introduced to a dance and engineering curriculum, microcontrollers, sensors, dance concepts, and choreography tools. Spells noticed during the workshop fundamental changes in the girls' interest and development with respect to technology. For example, after successfully assembling circuits and soldering boards, one student expressed an interest in taking a computer science course at her high school. Her successes in the space validated her curiosity to explore computer science in a formal environment.

Mariam Asad is a Ph.D. Student in Digital Media and is advised by Christopher Le Dantec. Asad's current work is in the design and development of a digital advocacy toolkit. This work focuses on developing digital tools to address systemic social issues- like housing, transportation, or food access- using integrated, hybrid approaches to address a community's specific, contextual needs. Any one social issue is multi-faceted and complex with unique histories and contingencies, and solutions to these issues are similarly complex and cannot be found in any one domain.. Asad focuses on how to design digital interventions- tools, platforms, applications- to address various needs and influence political change and civic work. Her research draws on three years of ethnographic work with a local housing justice activist group working towards more equitable housing practices. The group used online tools to complement their offline civic work: e-conference call tools supported training sessions; mailing lists broadcasted fundraising efforts; and social media coordinated protect actions, like marches, vigils, or sit-ins. Asad is continuing to work with this group to design and implement tools to help support future civic work and empower local communities.

Laura Barg-Walkow is a Ph.D. Student in Engineering Psychology and is advised by Wendy Rogers. Barg-Walkow's primary research focus is on applications of engineering psychology for improving healthcare systems. She was worked on many projects in this area, ranging from understanding medical device use errors to researching health and wellness in an aging population. One such project was developing the System for Tracking and Managing Pain (STAMP), designed to improve pain management and shared medical decision-making through visualizing patterns of pain levels as they relate to factors affecting pain (e.g., exercise, mood). STAMP was tested with two user groups - older adults and health care providers - and was a multi-year collaboration between academia, industry, and a healthcare professional group. Barg-Walkow devised and conducted usability studies, conducted heuristic evaluations of the interface, and provided design recommendations for improving the software prototype of STAMP. She was involved in all aspects of this iterative process, from designing the method to user testing to demonstrating the system's potential efficacy.

Maia Jacobs is a Ph.D student in Human-Centered Computing and is advised by Beth Mynatt. Jacobs is examining the real world benefits of personalized health tools for cancer patients by developing technology that reflects information about individual patients and provides customized support and resources to users. The aim of the research project is to study how to design appealing and usable personalized user experiences that help patients better manage chronic diseases. Developing personalized health tools presents significant challenges. The technology must possess the flexibility and robustness to cater to the full range of an individual patient's needs in order to make an overwhelming experience like being diagnosed with cancer manageable on a day-to-day basis. The technology must be able to adapt along with the patient, while maintaining an easy-to-use and engaging interface. Targeted help in the home could make a significant difference in supporting patients' individual needs and ultimately impacting health outcomes. For her study, Jacobs is designing tablets that will utilize an adaptive interface to present personalized support to breast cancer patients. The tablets will highlight new resources and make recommendations to patients based on data from health systems and patients themselves.

Lauren Margulieux is a Ph.D. Student in Engineering Psychology and is advised by Richard Catrambone. Margulieux's research interests center on supporting students in unsupervised learning environments through educational technology, especially in online courses in which students rely more on self-taught skills to be successful. In a recent study, she compared teaching methods used in face-to-face learning to those used in online learning to identify the teaching methods that are most effective in each environment. Then she analyzed learning outcomes from courses that mixed face-to-face and online learning together. These courses - typically called flipped, hybrid, or blended learning - have been defined by practitioners in different ways, preventing researchers and educators from aggregating research results in a meaningful way. Margulieux developed a taxonomy to better define and differentiate types of courses that mix face-to-face and online learning together. Using the taxonomy, she discovered trends in learning outcomes resulting from online learning. She found that providing feedback to students was crucial for improving learning outcomes when those students attempt to apply their knowledge and practice new skills. More specifically, when instructors provided this feedback, learning almost always improved, and when technology provided feedback, learning improved in half of the cases.

Briana Morrison is a Ph.D. Candidate in Human-Centered Computing and is advised by Mark Guzdial. Morrison is currently researching findings that indicate learning computer science is significantly different than other problem solving domains where certain educational psychology principles apply. Her work has shown that the overall cognitive load of learning programming is significantly higher than learning other STEM disciplines due to the nature of the material itself. Using a cognitive measurement tool that she developed, she can measure the intrinsic load component of learning to program. Establishing the fact of a high intrinsic cognitive load can positively impact other aspects of teaching programming – even how explanations of code are delivered to minimize the transience effect. The research would aid in furthering the development of instructional material specifically aimed at reducing the amount of intrinsic cognitive load imposed at one time on the learner. It can also decompose programming into simpler elements and develop specific practice style problems to aid all learners.

Mason Bretan
Robotic and Human Musical Performances

Mason Bretan is a Ph.D. candidate in Music Technology and is advised by Gil Weinberg. His research focus is robotic musicianship, which includes developing systems that interact with humans through musical scenarios. Such systems include robots that play acoustic instruments, musical companion robots, and robotic prostheses for amputee musicians. Using sophisticated technology and artificial intelligence, Bretan enables these machines to respond to human creativity in meaningful ways and even inspire humans to be creative, ultimately leading to novel and interesting artistic experiences. This entails the creation of computational models describing aspects of music perception, improvisation, and interaction. A current project that encapsulates these goals is the development of a robotic prosthesis for an amputee drummer. There are two main objectives in this work: 1) provide the amputee with the drumming-specific functionalities he lost as a result of losing his arm and 2) create a semi-autonomous third arm that listens and responds to the drummer's play allowing for interesting music to emerge through a new and unique human-robotic interactive paradigm. Bretan designed the entire infrastructure for real-time low level control of the motors and higher-level commands such as simulated drum strikes.

Deana Brown
HCI for Immigrant and Refugee Populations

Deana Brown is a Ph.D. student in Human-Centered Computing and is advised by Beki Grinter. Brown designs, prototypes and studies social and ubiquitous technologies. Her research spans Social Computing, Human-Computer Interaction, Ubiquitious Computing, and Information and Communication Technologies for Development. Her work has been based in emerging markets within the Caribbean and Sub-Saharan Africa as well as within immigrant and refugee groups in the United States. As part of her work with these groups, Brown developed a collaborative tool called Rivrjam, accessible through a simple phone call or via a website, to mediate the exchange of voice and text messages sent between parents and their children's educators, tutors and academic mentors. The application stores, reroutes and (in the case of refugees) facilitates the translation of messages through the help of interpreters working at refugee agencies. As a first means of evaluating the tool's effectiveness, Brown deployed it at a public high school in Jamaica to support parent-school exchange with migrant parents living in the U.S. and U.K. The study found that it helped to improve the range of support an already active parent could provide to a child with increased knowledge of their needs and challenges.

Alex Zook
Artificial Intelligence for Games With a Purpose

Alex Zook is a Ph.D. Candidate in Human-Centered Computing and is advised by Mark Riedl. His research develops artificially intelligent (AI) systems to augment game design and development. While games are being used for an ever-broadening array of purposes - education and training, citizen science and data collection, or even health and social change - developing games remains a daunting challenge. Further, people making games (educators, scientists or health professionals) often lack the skills and time to create games. Zook has developed a system (now licensed to the Army Research Lab, Simulation and Training Technology Center) to automatically adapt game content to train players on their weakest skills using big data techniques. He has also developed systems to: (1) automate the time-consuming process of collecting data from human game players and tuning a game design to achieve a designer's objectives and (2) automate the process of defining game mechanics that ensure a game level or puzzle can be completed. Alex is currently working to integrate these methods into a system that automatically generates games for human-specified objectives and refines those games through tests with humans to optimize them for their design goals.

Aditi Misra
Data Patterns in Cyclists' Routes

Aditi Misra is a Ph.D. student in Transportation Systems and is advised by Kari Watkins. Her primary research interest is in creating connected neighborhoods and cities where people of all ages, cultures and capabilities will live and thrive. Through her work, Misra hopes to help create transportation infrastructure systems that are designed based on the preferences of its users, and are hence more likely to cater to the needs of most of its users. Her particular focus is on resolving issues by uncovering patterns from collected data to understand and predict user preferences. She is currently working on developing a methodology to predict the preferred route choice of bicyclists in Atlanta based on their socio-demographic characteristics as well as their previously chosen route characteristics. The aim of this research project is to identify corridors where dedicated cycling facilities are needed in order to encourage people in biking. The data on cyclists and their chosen route is collected through a GPS enabled smartphone based application named Cycle Atlanta (, which was developed as a collaboration between Georgia Tech and the City of Atlanta to provide the citizens with a flexible and equitable participatory planning platform. The proposed choice model will help the City of Atlanta to understand the requirements of different cyclist types in Atlanta, thus enabling the city to allocate infrastructure resources in the most optimal way when the funding is constrained.

Andrew Quitmeyer
Exploratory and Communicative Digital Devices in Digital Naturalism

Andrew Quitmeyer is a Ph.D. student in Digital Media and is advised by Michael Nitsche. He is pursuing his research in “Digital Naturalism”. He works with animal behavior field scientists to develop exploratory and communicative digital devices. The Smithsonian Tropical Research Institute in Panama named him a Fellow for Summer 2013 and 2014. He conducted research in the tropical rainforest, studying wild animals such as ants and bats while investigating digital technology's use in complex, harsh environments. The goal of his research is to investigate the role that Digital Media can play in biological field work. Working with biologists in the GT Robotics lab showed Quitmeyer that many activities valuable to a field scientist's entire process are not receiving the same technological attention. For instance, digital devices used for outdoor experimentation face greater challenges than those employed in controlled laboratories. Additionally, few digital tools are being designed to empower field researcher's earliest open-ended field explorations or in figuring out new ways to share their research discoveries with others.

Advancing the State of the Art in Digital Games

Chris Deleon is a Ph.D. student in Digital Media and is advised by Celia Pearce. Chris's current research is focused on the differences between game design for digital games as compared to non-digital games, with an emphasis on how those differences may affect educational practices and professional discourse. His goal is to help more people get a handle on creating their own videogames in a way that better explores the affordances of the medium. Chris's research vision is to redirect his work from serving as pure entertainment toward education, cultural enrichment, and better communicating obscure ideas. Chris earned his master's degree in Digital Media from Georgia Tech in 2012 and a bachelor's degree in Computer Science from Carnegie Mellon in 2007.

Iulian Radu
Augmented Reality Experiences for Kids

Iulian Radu is a Ph.D. student in Human-Centered Computing and is advised by Blair MacIntyre. Iulian is researching how to design augmented-reality experiences that are suitable for young children, 6 years of age and older. In the AR community there are few "best practices" or guidelines for how to design AR experiences that are suitable for children of specific ages. The difficulty is that one AR design for a specific age group may not be suitable for another, because children develop over time and they have different capabilities and limitations due to their physical, cognitive, emotional and social development. Iulian is developing approaches to determine how developmental psychology can help others to understand and improve AR designs for children.

Jie Tan
Computer Simulation to Real-Life Robotics Control of Bikes

Jie Tan is a Ph.D. candidate in Computer Science and is advised by Karen Liu and Greg Turk. Jie develops computational tools that facilitate simulation of human and animal motion. He is currently studying how to teach a virtual human character to ride a bicycle in a physically simulated environment. His motivation behind the project: to advance a robotics-enabled future. Society envisions humanoid robots with advanced artificial intelligence becoming family members who will protect, cook, do laundry and even look after the elderly. One important step to realize this vision is to build robots that can actively learn - teaching a robot to ride a bicycle under various real-life situations is the ultimate goal of Jie's work. Riding a bicycle is challenging for robots due to the inherently unstable dynamics. Controlling balance on a bike involves sophisticated and robust neuro-mechanical control, which is also vital for many other complicated robotic tasks and could be applied to their learning.

Casey Fiesler is a Ph.D. candidate in Human-Centered Computing and is advised by Amy Bruckman. Armed with a law degree from Vanderbilt University Law School, she studies the intersection of technology and copyright law. Casey is particularly interested in how the law - and perceptions of the law - impact creativity online, and her dissertation work focuses on social norms and knowledge about intellectual property in online communities of remixers. By focusing on an area where the law is notoriously gray, she is discovering how ordinary Internet users make complex decisions about legal concepts that can baffle even lawyers. Along with her law degree, Casey holds an master's degree in Human-Computer Interaction and a bachelor's degree in Psychology from Georgia Tech. Also interested in copyright advocacy, she has interned for Creative Commons and sits on the legal committee for the Organization for Transformative Works.

Caleb Southern
Mobile System for Real-Time Driving Costs

Caleb Southern is a Ph.D. student in Human-Centered Computing, and is advised by Gregory Abowd. Caleb has developed a system to allow people to see the cost of each driving trip they take in real time. Caleb has found that the total cost of driving for many people is between 50 cents and one dollar per mile, including the depreciation of the vehicle, insurance, maintenance, and other factors (average annual cost to own and operate a vehicle in United States is $8K). He is studying how information technology can increase people's awareness of their transportation activities and influence their behavior. With his system, drivers can see the total cost of each trip as they arrive at their destination. People can also see historical data, and reflect on trends in their driving costs over time. Caleb is measuring people's reactions and changes in driving behavior in response to the cost information his system provides.

Alex Zook
Artificial Intelligence for Games With a Purpose

Alex Zook is a Ph.D. Candidate in Human-Centered Computing and is advised by Mark Riedl. Alex's research investigates how artificially intelligent (AI) systems can augment the process of designing and developing games, specifically targeting data-driven design. Currently he is focusing on AI systems that automatically generate and improve games with a purpose (GWAPs). GWAPs are simple games that embed a computational process within a game design, enabling people to simultaneously play a game and perform some computational task or provide some real-world data. While a plethora of GWAPs have been created, the space of possible problems in which they might be used is rapidly growing. Developing AI systems that can automatically determine the appropriate GWAP design for a given target problem holds great promise to meet these needs for automated data collection or task execution. The projects Alex is pursuing are (1) employing AI for GWAPs used to gather real-world location-based information and (2) GWAPs for assessing individual personality traits. Ultimately Alex hopes this research will improve techniques for creating GWAPs to meet real-world needs and provide support to human.

Jill Fantauzzacoffin
Integrating Art and Engineering for Innovation and Education

Jill Fantauzzacoffin is a Ph.D. candidate in the Digital Media program, advised by Jay Bolter. Jill's artwork installations incorporate high technology and interactivity, and often produce novel interactive technologies. Her current artwork-in-progress has spun off a series of haptic (touch-based) technologies which have led to a patent application filing through Georgia Tech and a Georgia Research Alliance commercialization grant. These flexible, high-resolution haptic technologies hold promise in the cell-phone and videogame controller industries as well as in therapeutic textiles addressing SIDS and PTSD. Jill has also initiated and carried out NSF research comparing the creative practices of artists and engineers.
