Workforce diversity is imperative for innovative science and technology. Yet due to funding inequities, research infrastructure isn’t as robust at Minority Serving Institutions (MSIs), making building a diverse workforce pipeline and inclusive research collaborations challenging. With its Research Collaboration Initiative (RCI), the Georgia Institute of Technology is building MSI partnerships and recently hosted its first research collaboration forum (RCF) specifically to develop these relationships with Historically Black Colleges and Universities (HBCUs).

Nearly 170 attendees from government, industry, national labs, and other universities gathered on the Georgia Tech campus Nov. 7 – 8. The research forum featured keynotes, panels, and breakout sessions divided by research area to develop the partnerships necessary for meaningful collaboration.

Dietra Trent — executive director of White House Initiatives on Advancing Educational Equity, Excellence, and Economic Opportunity through HBCUs — gave the morning keynote.

“Research shaped by diverse experience and cultures will reduce the risk of bias and create significant opportunities for all our universities,” she said. “This collaboration represents one of the best ways to build a scholarly community. It’s the partnership our HBCUs need — not a handout but a hand up.”

Day one of the RCF featured keynotes talks from Senior Advisor Terrence Mosely of the Office of Energy Efficiency and Renewable Energy and Thyaga Nandagopal, director of the Division of Innovation and Technology Ecosystems in Tech, Innovation, and Partnerships.

The second day featured a keynote from Victoria Coleman, who currently serves as the chief scientist of the U.S. Air Force and was past director of the Defense Research Projects Agency. Coleman was instrumental in creating the first HBCU-led University Affiliated Research Center in Tactical Autonomy.

Keynotes from Kylie Patterson, director of opportunity and inclusion from CHIPS.gov, and Annette Owens-Scarsboro, the National Institutes of Health (NIH) institution program manager for HBCUs and MSIs, rounded out the second day.

Panels about funding priorities for the Department of Energy, the National Science Foundation, the Department of Commerce, NIH, and the Department of Defense offered attendees compelling federal research opportunities. In breakout sessions, attendees gathered to ideate and team build within their respective research disciplines, which included everything from climate resiliency to artificial intelligence.

“We’re looking at these breakout sessions as an opportunity to develop long-term, sustainable collaborations and partnerships between our respective institutions,” said George White, senior director for strategic partnerships in the Office of the Vice President for Interdisciplinary Research and principal research engineer at Georgia Tech. “We believe this is an enduring model that can grow well beyond Georgia Tech. The ability to seed research projects and capacity building makes this a very unique opportunity.”

Throughout the forum, there were multiple opportunities to network and build more casual partnerships.

“The goal is to exchange ideas, meet one another, and identify areas of collaborative synergy,” said Taiesha Smith, senior program manager of HBCU/MSI Research Partnerships at Georgia Tech.

Inclusivity Imperative to Research Next

The RC is just one of the projects of Research Next. Executive Vice President for Research Chaouki T. Abdallah launched the research enterprise’s planning initiative in 2020, and creating inclusive research collaborations is its third phase.

“We believe that in order to develop lasting solutions for the problems facing humanity, we need as many perspectives as possible,” he said. “We need more original ideas, the kind of ideas born from having diverse communities to not just make the solutions but to ask the right questions.”

The event was one of Georgia Tech’s many efforts in this area. The team created a software tool, CollabNext, where researchers can find partners at HBCUs with similar disciplines and interests. They also developed a memorandum of understanding for a semiconductor research initiative with HBCU/MSIs. Even the Georgia Tech Research Institute is involved, developing the Defense-University Affiliated Research Traineeship to give HBCU students opportunities in the Department of Defense.

“This event will energize and identify opportunities from companies and the federal government to make sure HBCU and MCIS can compete for the funding,” Abdallah said, “because they have built the infrastructure to conduct this research.”

 

Researchers have documented for the first time the stresses that build up around solid-state battery electrolytes, helping set the stage for the development of improved and more efficient batteries. Scientists have long thought that stresses can build up around dendrites, thin metallic projects that can ultimately short out solid-electrolyte batteries, but they haven’t been precisely measured.

A team of scientists at Georgia Tech, Brown University, Nanyang Technological University, and MIT have measured the mechanical stresses that develop in dendrites – solving a long-standing hypothesis that high stresses can be developed around dendrites. Dendrites pierce through solid electrolytes, eventually crossing from one electrode to the other and shorting out the solid-state battery cell.

Georgia Tech Professor Christos Athanasiou and the multidisciplinary team used photoelasticity to measure the stress on batteries caused during the battery cycle. In their paper, Operando Measurements of Dendrite-Induced Stresses in Ceramic Electrolytes using Photoelasticity, they managed to overcome challenges associated with measurements of easy to break, very tiny solid electrolyte samples. The samples thickness was about 10 times smaller than the average diameter of human hair.

The team used an old - and almost forgotten - principle of photoelasticity to directly measure the stress fields during cell operation. Photoelasticity’s contactless nature also allows for the stresses to be directly measured and visualized at the dendrite tips. By shining light through the material under a special photoelastic microscope, it revealed intricate stress fields. In this case, the stress revealed from passing light through the electrolyte appeared at the tip of the propagation dendrite.

This advanced experimental setup has set the stage for profound exploration of stresses developed during battery operation across various electrolytes and conditions, revealing critical data on loading conditions and the dynamics of lithium metal penetration events.

This is just one example where creative, yet simple experimentation, can lead to fundamental discoveries. The Daedalus Lab at Georgia Tech, inspired by the ingenuity of its namesake, the mythical Greek inventor, is dedicated to decarbonizing the future through the development and promotion of sustainable materials and structures, utilizing innovative experimental approaches and artificial intelligence.

Juan-Pablo Correa-Baena leads the Materials for Solar Energy Harvesting and Conversion research initiative for the Institute for Materials (IMat) and Strategic Energy Institute at Georgia Tech. In this role, he is working to create a community around solar energy harvesting and conversion at Georgia Tech. He aims to integrate photovoltaic, photodetectors, and related devices into IMaT-related research; energize research in these areas at Georgia Tech at large; and consolidate the expertise of the many research groups working on or around photovoltaics/photodetectors that will allow researchers to target interdisciplinary research funding opportunities. He is also an assistant professor and the Goizueta Junior Faculty Rotating Chair in the School of Materials Science and Engineering.

In this brief Q&A, Correa-Baena discusses his research focus, how it relates to materials research, and the impact of this initiative.

What is your field of expertise and at what point in your life did you first become interested in this area?

I am an expert in materials for energy harvesting and conversion. I first became interested in this topic when I was an undergraduate student and started thinking about the future of energy production. 

What questions or challenges sparked your current materials research?

I was born and raised in a country where fossil fuels dominate the energy production landscape, yet where renewables are readily available. Colombia is a large producer of oil but also boasts a huge potential for solar energy production. This juxtaposition always puzzled me growing up. As a researcher in this field, I want to ensure that all countries around the world have access to solar energy, by helping lower deployment cost. 

Why is your initiative important to the development of Georgia Tech’s Materials research strategy?

There is a growing need to expand our research footprint at Georgia Tech with regard to photovoltaics. This is especially important with the impact of the photovoltaic industry presence in Georgia. My initiative is focusing on galvanizing activities around photovoltaic research at Georgia Tech that can benefit our footprint globally as well as locally with industry partners.

What are the broader global and social benefits of the research you and your team conduct?

The main benefit of the research we do is to the photovoltaic industry, which we hope to engage through cutting-edge research at Georgia Tech.

What are your plans for engaging a wider Georgia Tech faculty pool with IMat research?

I am planning to organize an internal workshop, as well as a session on photovoltaics in the Next Generation of Energy Materials Symposium to be held in March 2024 at Georgia Tech. In addition, as part of my efforts to engage the Georgia Tech community at large, I am working to create a website that will connect the Georgia Tech community working towards advancing photovoltaic capabilities for future manufacturing advancements. 

Projects address basic research challenges facing the Energy Earthshots Initiative to mitigate climate change and reach a net-zero carbon economy.

The Institute for Data Engineering and Science, in conjunction with several Interdisciplinary Research Institutes (IRIs) at Georgia Tech, have awarded seven teams of researchers from across the Institute a total of $105,000 in seed funding geared to better position Georgia Tech to perform world-class interdisciplinary research in data science and artificial intelligence development and deployment. 

The goals of the funded proposals include identifying prominent emerging research directions on the topic of AI, shaping IDEaS future strategy in the initiative area, building an inclusive and active community of Georgia Tech researchers in the field that potentially include external collaborators, and identifying and preparing groundwork for competing in large-scale grant opportunities in AI and its use in other research fields.

Below are the 2023 recipients and the co-sponsoring IRIs:

 

Proposal Title: "AI for Chemical and Materials Discovery" + “AI in Microscopy Thrust”
PI: Victor Fung, CSE | Vida Jamali, ChBE| Pan Li, ECE | Amirali Aghazadeh Mohandesi, ECE
Award: $20k (co-sponsored by IMat)

Overview: The goal of this initiative is to bring together expertise in machine learning/AI, high-throughput computing, computational chemistry, and experimental materials synthesis and characterization to accelerate material discovery. Computational chemistry and materials simulations are critical for developing new materials and understanding their behavior and performance, as well as aiding in experimental synthesis and characterization. Machine learning and AI play a pivotal role in accelerating material discovery through data-driven surrogate models, as well as high-throughput and automated synthesis and characterization.

Proposal Title: " AI + Quantum Materials”
PI: Zhigang JIang, Physics | Martin Mourigal, Physics
Award: $20k (Co-Sponsored by IMat)

Overview: Zhigang Jiang is currently leading an initiative within IMAT entitled “Quantum responses of topological and magnetic matter” to nurture multi-PI projects. By crosscutting the IMAT initiative with this IDEAS call, we propose to support and feature the applications of AI on predictive and inverse problems in quantum materials. Understanding the limit and capabilities of AI methodologies is a huge barrier of entry for Physics students, because researchers in that field already need heavy training in quantum mechanics, low-temperature physics and chemical synthesis. Our most pressing need is for our AI inclined quantum materials students to find a broader community to engage with and learn. This is the primary problem we aim to solve with this initiative.

PI: Jeffrey Skolnick, Bio Sci | Chao Zhang, CSE
Proposal Title: Harnessing Large Language Models for Targeted and Effective Small Molecule 4 Library Design in Challenging Disease Treatment
Award: $15k (co-sponsored by IBB)

Overview: Our objective is to use large language models (LLMs) in conjunction with AI algorithms to identify effective driver proteins, develop screening algorithms that target appropriate binding sites while avoiding deleterious ones, and consider bioavailability and drug resistance factors. LLMs can rapidly analyze vast amounts of information from literature and bioinformatics tools, generating hypotheses and suggesting molecular modifications. By bridging multiple disciplines such as biology, chemistry, and pharmacology, LLMs can provide valuable insights from diverse sources, assisting researchers in making informed decisions. Our aim is to establish a first-in-class, LLM driven research initiative at Georgia Tech that focuses on designing highly effective small molecule libraries to treat challenging diseases. This initiative will go beyond existing AI approaches to molecule generation, which often only consider simple properties like hydrogen bonding or rely on a limited set of proteins to train the LLM and therefore lack generalizability. As a result, this initiative is expected to consistently produce safe and effective disease-specific molecules.

PI: Yiyi He, School of City & Regional Plan | Jun Rentschler, World Bank
Proposal Title: “AI for Climate Resilient Energy Systems”
Award: $15k (co-sponsored by SEI)

Overview: We are committed to building a team of interdisciplinary & transdisciplinary researchers and practitioners with a shared goal: developing a new framework which model future climatic variations and the interconnected and interdependent energy infrastructure network as complex systems. To achieve this, we will harness the power of cutting-edge climate model outputs, sourced from the Coupled Model Intercomparison Project (CMIP), and integrate approaches from Machine Learning and Deep Learning models. This strategic amalgamation of data and techniques will enable us to gain profound insights into the intricate web of future climate-change-induced extreme weather conditions and their immediate and long-term ramifications on energy infrastructure networks. The seed grant from IDEaS stands as the crucial catalyst for kick-starting this ambitious endeavor. It will empower us to form a collaborative and inclusive community of GT researchers hailing from various domains, including City and Regional Planning, Earth and Atmospheric Science, Computer Science and Electrical Engineering, Civil and Environmental Engineering etc. By drawing upon the wealth of expertise and perspectives from these diverse fields, we aim to foster an environment where innovative ideas and solutions can flourish. In addition to our internal team, we also have plans to collaborate with external partners, including the World Bank, the Stanford Doerr School of Sustainability, and the Berkeley AI Research Initiative, who share our vision of addressing the complex challenges at the intersection of climate and energy infrastructure.

PI: Jian Luo, Civil & Environmental Eng | Yi Deng, EAS
Proposal Title: “Physics-informed Deep Learning for Real-time Forecasting of Urban Flooding”
Award: $15k (co-sponsored by BBISS)

Overview: Our research team envisions a significant trend in the exploration of AI applications for urban flooding hazard forecasting. Georgia Tech possesses a wealth of interdisciplinary expertise, positioning us to make a pioneering contribution to this burgeoning field. We aim to harness the combined strengths of Georgia Tech's experts in civil and environmental engineering, atmospheric and climate science, and data science to chart new territory in this emerging trend. Furthermore, we envision the potential extension of our research efforts towards the development of a real-time hazard forecasting application. This application would incorporate adaptation and mitigation strategies in collaboration with local government agencies, emergency management departments, and researchers in computer engineering and social science studies. Such a holistic approach would address the multifaceted challenges posed by urban flooding. To the best of our knowledge, Georgia Tech currently lacks a dedicated team focused on the fusion of AI and climate/flood research, making this initiative even more pioneering and impactful.

Proposal Title: “AI for Recycling and Circular Economy”
PI: Valerie Thomas, ISyE and PubPoly | Steven Balakirsky, GTRI
Award: $15k (co-sponsored by BBISS)

Overview: Most asset management and recycling-use technology has not changed for decades. The use of bar codes and RFID has provided some benefits, such as for retail returns management. Automated sorting of recyclables using magnets, eddy currents, and laser plastics identification has improved municipal recycling. Yet the overall field has been challenged by not-quite-easy-enough identification of products in use or at end of life. AI approaches, including computer vision, data fusion, and machine learning provide the additional capability to make asset management and product recycling easy enough to be nearly autonomous. Georgia Tech is well suited to lead in the development of this application. With its strength in machine learning, robotics, sustainable business, supply chains and logistics, and technology commercialization, Georgia Tech has the multi-disciplinary capability to make this concept a reality; in research and in commercial application.

Proposal Title: “Data-Driven Platform for Transforming Subjective Assessment into Objective Processes for Artistic Human Performance and Wellness”
PI: Milka Trajkova, Research Scientist/School of Literature, Media, Communication | Brian Magerko, School of Literature, Media, Communication
Award: $15k (co-sponsored by IPaT)

Overview: Artistic human movement at large, stands at the precipice of a data-driven renaissance. By leveraging novel tools, we can usher in a transparent, data-driven, and accessible training environment. The potential ramifications extend beyond dance. As sports analytics have reshaped our understanding of athletic prowess, a similar approach to dance could redefine our comprehension of human movement, with implications spanning healthcare, construction, rehabilitation, and active aging. Georgia Tech, with its prowess in AI, HCI, and biomechanics is primed to lead this exploration. To actualize this vision, we propose the following research questions with ballet as a prime example of one of the most complex types of artistic movements: 1) What kinds of data - real-time kinematic, kinetic, biomechanical, etc. captured through accessible off-the-shelf technologies, are essential for effective AI assessment in ballet education for young adults?; 2) How can we design and develop an end-to-end ML architecture that assesses artistic and technical performance?; 3) What feedback elements (combination of timing, communication mode, feedback nature, polarity, visualization) are most effective for AI- based dance assessment?; and 4) How does AI-assisted feedback enhance physical wellness, artistic performance, and the learning process in young athletes compared to traditional methods?

Researchers at Georgia Tech will work to develop new controllable materials for 3D printing, electronics made from plastics, and semiconductors that convert infrared light into electrical signals as part of the National Science Foundation’s (NSF) efforts to create advanced materials.

Altogether, the agency is investing $3 million in the three projects led by faculty members in the George W. Woodruff School of Mechanical Engineering (ME) and the School of Materials Science and Engineering (MSE). Georgia Tech is a contributing partner on a fourth project led by Notre Dame researchers to explore materials that can be switched from an insulator to a metal with an external trigger.

The new awards are part of NSF’s Designing Materials to Revolutionize and Engineer our Future (DMREF) program, which is intended to discover and create advanced materials twice as fast and at a fraction of the cost of traditional research methods.

Three Georgia Tech School of Earth and Atmospheric Sciences researchers — Professor and Associate Chair Annalisa Bracco, Professor Taka Ito, and Georgia Power Chair and Associate Professor Chris Reinhard — will join colleagues from Princeton, Texas A&M, and Yale University for an $8 million Department of Energy (DOE) grant that will build an “end-to-end framework” for studying the impact of carbon dioxide removal efforts for land, rivers, and seas. 

The proposal is one of 29 DOE Energy Earthshot Initiatives projects recently granted funding, and among several led by and involving Georgia Tech investigators across the Sciences and Engineering.

Overall, DOE is investing $264 million to develop solutions for the scientific challenges underlying the Energy Earthshot goals. The 29 projects also include establishing 11 Energy Earthshot Research Centers led by DOE National Laboratories. 

The Energy Earthshots connect the Department of Energy's basic science and energy technology offices to accelerate breakthroughs towards more abundant, affordable, and reliable clean energy solutions — seeking to revolutionize many sectors across the U.S., and relying on fundamental science and innovative technology to be successful.

Carbon Dioxide Removal 

The School of Earth and Atmospheric Sciences project, “Carbon Dioxide Removal and High-Performance Computing: Planetary Boundaries of Earth Shots,” is part of the agency’s Science Foundations for the Energy Earthshots program. Its goal is to create a publicly-accessible computer modeling system that will track progress in two key carbon dioxide removal (CDR) processes: enhanced earth weathering, and global ocean alkalinization. 

In enhanced earth weathering, carbon dioxide is converted into bicarbonate by spreading minerals like basalt on land, which traps rainwater containing CO2. That gets washed out by rivers into oceans, where it is trapped on the ocean floor. If used at scale, these nature-based climate solutions could remove atmospheric carbon dioxide and alleviate ocean acidification. 

The research team notes that there is currently “no end-to-end framework to assess the impacts of enhanced weathering or ocean alkalinity enhancement — which are likely to be pursued at the same time.” 

 “The proposal is for a three-year effort, but our hope is that the foundation we lay down in that time will represent a major step forward in our ability to track carbon from land to sea,” says Reinhard, the Georgia Power Chair who is a co-investigator on the grant. 

“Like many folks interested in better understanding how climate interventions might impact the Earth system across scales, we are in some ways building the plane in midair,” he adds. “We need to develop and validate the individual pieces of the system — soils, rivers, the coastal ocean — but also wire them up and prove from observations on the ground how a fully integrated model works.”

That will involve the use of several existing computer models, along with Georgia Tech’s PACE supercomputers, Professor Ito explains. “We will use these models as a tool to better understand how the added alkalinity, carbon and weathering byproducts from the soils and rivers will eventually affect the cycling of nutrients, alkalinity, carbon and associated ecological processes in the ocean,” Ito adds. “After the model passes the quality check and we have confidence in our output, we can start to ask many questions about assessment of different carbon sequestration approaches or downstream impacts on ecosystem processes.”

Professor Bracco, whose recent research has focused on rising ocean heat levels, says CDR is needed just to keep ocean systems from warming about 2 degrees centigrade (Celsius). 

“Ninety percent of the excess heat caused by greenhouse gas emissions is in the oceans,” Bracco shares, “and even if we stop emitting all together tomorrow, that change we imprinted will continue to impact the climate system for many hundreds of years to come. So in terms of ocean heat, CDRs will help in not making the problem worse, but we will not see an immediate cooling effect on ocean temperatures. Stabilizing them, however, would be very important.”

Bracco and co-investigators will study the soil-river-ocean enhanced weathering pipeline “because it’s definitely cheaper and closer to scale-up.” Reverse weathering can also happen on the ocean floor, with new clays chemically formed from ocean and marine sediments, and CO2 is included in that process. “The cost, however, is higher at the moment. Anything that has to be done in the ocean requires ships and oil to begin,” she adds.

Reinhard hopes any tools developed for the DOE project would be used by farmers and other land managers to make informed decisions on how and when to manage their soil, while giving them data on the downstream impacts of those practices.

“One of our key goals will also be to combine our data from our model pipeline with historical observational data from the Mississippi watershed and the Gulf of Mexico,” Reinhard says. “This will give us some powerful new insights into the impacts large-scale agriculture in the U.S. has had over the last half-century, and will hopefully allow us to accurately predict how business-as-usual practices and modified approaches will play out across scales.”

The Georgia Tech Energy, Policy, and Innovation Center, in partnership with Clean Cities Georgia, Atlanta Gas Light, Georgia Chamber of Commerce, Georgia Power, and Southface Institute, hosted the 2023 Clean Cities Georgia Transportation Summit in September. The event highlighted the successes and benefits of all forms of clean transportation in Georgia and across the nation and provided an opportunity for more than 100 attendees to network and build public-private partnerships. The summit also honored the 30th anniversary of the Department of Energy’s (DOE) National Clean Cities Network, and Clean Cities Georgia, which was the first coalition founded in 1993.

Tim Lieuwen, executive director of the Georgia Tech Strategic Energy Institute, Ian Skelton, natural gas vehicles director of Atlanta Gas Light, and Frank Norris, executive director of Clean Cities Georgia, provided the welcome and opening remarks followed by a panel of executives from UPS, Chevron, and the DeKalb County Fleet Management who discussed the benefits of adopting clean fuels for businesses.

“I am excited that Georgia Tech continues to play an integral role in convening industry and community in the local region and helping to build strong relationships that will positively impact the regional and national energy landscape,” said Lieuwen, Regents’ Professor and David S. Lewis Jr. Chair in the Daniel Guggenheim School of Aerospace Engineering. “Events like this tap into the regional expertise within academia, businesses, nongovernmental organizations, and research facilities, which speaks to the vision of EPICenter.”

The daylong summit consisted of panels discussing use cases for alternate fuels available in the market: natural gas/renewable natural gas, electric vehicle (EV) applications, propane and renewable propane, biofuels and sustainable aviation fuels, and current and future hydrogen applications. Panelists shared processes and considerations that led to the successful implementation of alternate fuels within their organization, including choosing locations, procurement, state and regional policies, incentives, effects on the community, improvements in current processes, reduced carbon footprint, and scalability while shifting from fossil to alternate fuels.

Panelists from Cobb, DeKalb, and Henry counties shared successful implementations of alternate fuel vehicles in their respective localities that included propane, renewable natural gas and EVs and showcased some of their alternate fuel vehicles during the summit. Workforce development and infrastructure concerns included training new electricians, aging line men in the region, and future proofing charging stations. Transformer supply chain issues were also brought to the forefront during discussions throughout the day.

Representatives from the Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency spoke to the audience on how to work with their respective agencies to get federal funding in this area. The event ended with a 30-year review of Clean Cities Georgia, a nonprofit that started as the first initiative of the DOE to focus on strategies to reduce petroleum consumption in transportation. There are now nearly 100 coalitions across the country.

The event was part of National Drive Electric Week, which took place during the last week of September. Presentations and other details from the summit can be accessed through the 2023 Clean Cities Georgia summit webpage.
