Engineers at Georgia Tech have designed a process that converts carbon dioxide removed from the air into useful raw material that could be used for new plastics, chemicals, or fuels.

Their approach dramatically reduces the cost and energy required for these direct air capture (DAC) systems, helping improve the economics of a process the researchers said will be critical to addressing climate change.

The key is a new kind of catalyst and electrochemical reactor design that can be easily integrated into existing DAC systems to produce useful carbon monoxide (CO) gas. It’s one of the most efficient such design ever described in scientific literature, according to lead researcher Marta Hatzell and her team. They published details April 16 in Energy and Environmental Science, a top journal for energy-related research.

The College of Sciences is funding two research centers through a new seed grant program. 

Selected from a finalist pool of nine proposals, Associate Professors Yuanzhi Tang and Thackery Brown’s ideas were chosen for their high potential for novel interdisciplinary research and impact. 

Tang’s center will focus on sustainable mineral research, and Brown’s on spatial computation and navigation. Applications for the research will span the development of more sustainable batteries, as well as seeking to improve human health and well-being.

“Improving the human condition, fostering community, and pursuing research excellence are at the forefront of Georgia Tech’s mission, and these new centers will play a critical role in furthering that goal,” says Laura Cadonati, associate dean for Research in the College of Sciences and a professor in the School of Physics. “The College of Sciences is thrilled to support these new initiatives, and is excited to continue to develop the seed grant program.” 

A second call for research center proposals is planned for January 2025, with funding to start in July 2025.

The new Center for Sustainable and Decarbonized Critical Energy Mineral Solutions (CEMS), to be led by Yuanzhi Tang, an associate professor in the School of Earth and Atmospheric Sciences, will serve as a hub for sustainable procurement solutions for critical energy mineral resources, including rare earth elements and metals used for battery production.

Thackery Brown, an associate professor in the School of Psychology, will lead the second center, the Center for Research and Education in Navigation (CRaNE). CRaNE will investigate problems related to spatial computation, cognition, and navigation — which has implications for human health, animal conservation, smart architecture and urban design.

“This generous support from the College of Sciences will enable us to host a conference on spatial cognition, computation, design, and navigation; to provide collaborative multi-lab seed grants; and to establish the first of a series of explicitly co-mentored, interdisciplinary graduate student Fellowships,” Brown says. “Collectively, these are the seeds of a high-impact and self-sustaining center.”

Co-sponsored by the College of Sciences, Strategic Energy Institute (SEI), Brook Byers Institute for Sustainable Systems (BBISS), Institute for Electronics and Nanotechnology (IEN), and Institute for Materials (iMat), CEMS began as a joint BBISS-SEI initiative lead project that has since grown into a joint center focused on critical elements and materials for sustainable energy.

Sustainably sourcing these materials provides a critical foundation for both high-tech industry and green economy. “Rare earth elements and battery metals like lithium, copper, and nickel are in high demand, but low domestic resources and production have resulted in a heavy reliance on imports,” Tang explains. “How can we domestically produce these resources, and how can we do this sustainably? Georgia Tech and the College of Sciences are in a unique position for developing a large regional research umbrella to connect these dots.”

CEMS will leverage on three key pillars: science and technology development, strengthening collaboration among the University System of Georgia (USG) universities, and developing regional resources and economy, Tang says. “By leveraging collaboration among Georgia universities, and fostering engagement with regional industries, the Center will develop new science and technology, leading the way in research on how to procure these ‘essential vitamins’ for clean energy transition in a sustainable and decarbonized manner.”

CRaNE will focus on solving problems related to spatial computation, cognition, and navigation. “How do we treat catastrophic loss of one’s ability to get from A to B in Alzheimer's disease? How do we build smarter cities that are easier and more carbon efficient to navigate? How can we develop robots,” Brown says, “which navigate with the flexibility and efficiency of our own minds? CRaNE will bring together experts from many different fields to help address these problems with truly creative and integrative scientific and technological solutions.”

CRaNE will support interdisciplinary collaborative research, including developing a graduate student fellowship program, and conducting K-12 outreach.

“Our goal for CRaNE is to position the College of Sciences, Georgia Tech, and our extended network of collaborator institutions as a center of gravity for cutting-edge work on how the mind, brain, and artificial systems process space — how they can be made better at it, and how we can engineer our world around us in ways that support the humans and animals that need to navigate it to survive,” Brown says.

Emphasizing the collaborative nature of CRaNE, Brown adds that “by targeting collaborative grants, research, and education, and by promoting outreach and education earlier in the STEM pipeline, we hope to accelerate progress at the frontiers of these fields — and to invest in future science that cannot be easily addressed by a single lab or discipline.”

This Earth Month more than 100 campus and community stakeholders gathered near the Georgia Tech EcoCommons for the 2024 Frontiers in Science: Climate Action Conference and Symposium.

On April 18, the College of Sciences hosted more than 20 speakers and panelists from across the Institute and Atlanta community presenting groundbreaking research and discussing innovations and ideas in climate change, challenges, and solutions. 

Georgia Tech President Ángel Cabrera (M.S. PSY 1993, Ph.D. PSY 1995) kicked off the morning sessions by highlighting the Institute’s new Climate Action Plan, which outlines the pathway to achieve net-zero emissions by 2050. Cabrera’s remarks focused on Georgia Tech’s role on the frontlines of research and education informing how we respond to climate challenges — and noted that the Institute’s work must extend beyond our laboratories and classrooms.

“It is essential that we not only do the science, but that we also tell that science to the world,” Cabrera says.

Interdisciplinary inquiry

This year, Frontiers in Science featured an array of climate research and initiatives led by the College of Sciences, fellow colleges across Georgia Tech, and the wider Atlanta community.

Following a three-year hiatus of the Frontiers series, the 2024 edition re-envisioned the signature annual event as a research conference and symposium to convene campus experts — and to incubate seed grant proposals to support the work of early career faculty.

Frontiers previously hosted Nobel laureates and invited thought leaders for individual talks across the College’s six schools, and celebrated milestones like the International Year of the Periodic Table of the Chemical Elements.

“This year, we wanted to showcase what we are doing right here in the College of Sciences and throughout the Institute,” says Susan Lozier, dean of the College of Sciences, Betsy Middleton and John Clark Sutherland Chair and professor in the School of Earth and Atmospheric Sciences. “Our faculty are at the forefront of broadening our knowledgebase and uncovering solutions in areas critical to the planet and our well-being. We wanted to uplift that work and see what sort of connections could be made.”

Connections and collaboration were key themes of the day as faculty, staff, students, and alumni participants representing all six Georgia Tech colleges shared research results and ongoing work and discussed collaborative ideas for horizons ahead.

“Scientists alone cannot [create accurate models],” noted Annalisa Bracco, professor in the School of Earth and Atmospheric Sciences and associate chair for Research, who shared her own research alongside Lozier, who presented a version of her 2024 TED Talk on ocean overturning. “Engineers alone cannot do it. We need social scientists, policy makers, communicators.”

The importance of an interdisciplinary approach was reinforced by the Strategic Energy Institute at Georgia Tech (SEI) and Brook Byers Institute for Sustainable Systems (BBISS), which announced an interdisciplinary seed grant funding opportunity for assistant professors with ideas for new climate solutions.

Frontiers in focus

Across three themed sessions, faculty and leadership from the Colleges of Sciences, Engineering, and Design spearheaded talks on the ocean and cryosphere, biodiversity, carbon cycling, coastal wetlands, biofuels production, and beyond.

Panels on climate challenges across community, technological, and policy initiatives were hosted by Georgia Tech Vice President for Interdisciplinary Research and Professor in the School of Biological Sciences and the School of Chemistry and Biochemistry Julia Kubanek.

Following a networking lunch with climate table topics, Georgia Tech Executive Vice President for Research and Professor in the School of Electrical and Computer Engineering Chaouki T. Abdallah (M.S. ECE 1982, Ph.D. ECE 1988) kicked off the afternoon sessions — which also announced the scholarship recipients of a student video competition and featured videos with a pair of alumnae working in meteorology, climate research, and policy.

Afternoon highlights also included discussions on the Georgia Tech Climate Action Plan and Sustainability Next initiative, led by Jennifer Chirico (B.S. MGMT 1997, Ph.D. PUBP 2011), associate vice president of Sustainability for Georgia Tech Infrastructure and Sustainability, and Jennifer Leavey (B.S. CHEM 1995), assistant dean for Faculty Mentoring in the College of Sciences and interim assistant director for Interdisciplinary Education in the Brook Byers Institute for Sustainable Systems.

Although many of the presentations provided a stern outlook of the state of our ecosystems, the conference concluded with a sense of hope. This optimism was grounded in the range of opportunities that exist to address climate challenges — thanks, in part, to the body of knowledge and solutions being tested and explored by Georgia Tech researchers.

At the end of the day, Katie Griffin, a first year undergraduate student in Environmental Science, read Amanda Gorman’s poem Earthrise and provided this reminder:

All of us bring light to exciting solutions never tried before
For it is our hope that implores us, at our uncompromising core,
To keep rising up for an earth more than worth fighting for.

With new vehicle models being developed by major brands and a growing supply chain, the electric vehicle (EV) revolution seems well underway. But, as consumer purchases of EVs have slowed, car makers have backtracked on planned EV manufacturing investments. A major roadblock to wider EV adoption remains the lack of a fully realized charging infrastructure. At just under 51,000 public charging stations nationwide, and sizeable gaps between urban and rural areas, this inconsistency is a major driver of buyer hesitance.

How do we understand, at a large scale, ways to make it easier for consumers to have confidence in public infrastructure? That is a major issue holding back electrification for many consumer segments.

- Omar Asensio, Associate Professor at Georgia Institute of Technology and Climate Fellow, Harvard Business School | Director, Data Science & Policy Lab

Omar Asensio, associate professor in the School of Public Policy and director of the Data Science and Policy Lab at the Georgia Institute of Technology, and his team have been working to solve this trust issue using the Microsoft CloudHub partnership resources. Asensio is also currently a visiting fellow with the Institute for the Study of Business in Global Society at the Harvard Business School.

The CloudHub partnership gave the Asensio team access to Microsoft’s Azure OpenAI to sift through vast amounts of data collected from different sources to identify relevant connections. Asensio’s team needed to know if AI could understand purchaser sentiment as negative within a population with an internal lingo outside of the general consumer population. Early results yielded little. The team then used specific example data collected from EV enthusiasts to train the AI for a sentiment classification accuracy that now exceeds that of human experts and data parsed from government-funded surveys.

The use of trained AI promises to expedite industry response to consumer sentiment at a much lower cost than previously possible. “What we’re doing with Azure is a lot more scalable,” Asensio said. “We hit a button, and within five to 10 minutes, we had classified all the U.S. data. Then I had my students look at performance in Europe, with urban and non-urban areas. Most recently, we aggregated evidence of stations across East and Southeast Asia, and we used machine learning to translate the data in 72 detected languages.”

We are excited to see how access to compute and AI models is accelerating research and having an impact on important societal issues. Omar's research sheds new light on the gaps in electric vehicle infrastructure and AI enables them to effectively scale their analysis not only in the U.S. but globally.

- Elizabeth Bruce, Director, Technology for Fundamental Rights, Microsoft

Asensio's pioneering work illustrates the interdisciplinary nature of today’s research environment, from machine learning models predicting problems to assisting in improving EV infrastructure. The team is planning on applying the technique to datasets next, to address equity concerns and reduce the number of “charging deserts.” The findings could lead to the creation of policies that help in the adoption of EVs in infrastructure-lacking regions for a true automotive electrification revolution and long-term environmental sustainability in the U.S.

The Center for Sustainable Communities Research and Education (SCoRE — formerly SLS), in collaboration with the Strategic Energy Institute (SEI), the Brook Byers Institute for Sustainable Systems (BBISS), the Renewable Bioproducts Institute (RBI), and the Social Equity and Environmental Engineering Lab (SEEEL), launched the Energy Equity, Environmental Justice, and Community Engagement Faculty Fellows Program in November 2023. In this program, Georgia Tech faculty learn how to work with communities, bringing together their academic knowledge and the local expertise of communities that has been developed through lived experience and long-standing social action.

The inaugural fellows include 24 Georgia Tech faculty from five Colleges, as well as a faculty colleague from Georgia Gwinnett College and a partner from the Southeast Energy Efficiency Alliance, who are building relationships with each other and with community partners in the areas of energy equity and environmental justice. Since the launch, they have engaged in a wide array of events, including community benefit and development workshops, site visits to community-based organizations across the Atlanta region, and university-community gatherings and symposia.

The program is expected to result in both collective and individual deliverables. Collective deliverables include the development of network mapping tools to facilitate collaborations inside and outside Georgia Tech, a set of principles for conducting community-engaged research, a reflective essay on faculty training for community-engaged research, and ideas for future activities to facilitate university-community and interdisciplinary team formation. Fellows individually determine their deliverables, which run the gamut from exploring partnerships for a specific research project to writing a societal impact statement for a tenure package.

More broadly, the program aims to grow Georgia Tech’s collaborative expertise in community-engaged research by forming a supportive network of faculty interested in community-engaged sustainability research and education.

Sustainable energy sources and environmental justice go hand in hand. Although such technologies aim to minimize environmental impacts of modern societies, without considering issues of environmental justice and energy equity, these solutions can inadvertently perpetuate disparities by disproportionately benefiting certain communities while harming others. Bridging the gap between technological advancements and community benefits is paramount to creating an equitable energy future for all.

This program provides a unique opportunity to explore these interconnections, enhancing my knowledge in integrating community values and concerns into my research on alternative fuels and renewable energy sources. I am particularly excited about the hands-on approach of the program, which emphasizes listening sessions and workshops, allowing fellows to gain direct insights from various stakeholders. I hope that, through active participation in these sessions, I can further my understanding of the challenges faced by local communities and incorporate these insights into actionable solutions in my research.

In my project, I'm in a group crafting a reflective essay about our experiences with Community Engaged Research training. Our goal is to translate the insights gained from this pilot program into a publishable piece. Additionally, I'm acquiring valuable insights into the development of Broader Impact Statements and Community Benefits Plans, crucial parts of proposals for securing federal funding from NSF and DoE, respectively.

Faculty Affiliate: Sofia Perez-Guzman, Assistant Professor, School of Civil and Environmental Engineering, Georgia Tech

The fellowship program has been a fantastic experience. I never imagined how much I would learn from this program about properly engaging with communities. As researchers, we might think we want to hear the needs that communities face to provide them with solutions. That is different than the way community-driven research should work. I’ve learned that researchers need to gain the communities’ trust, be present and participate in their events, and, more importantly, work at their pace and for their interests rather than push our research agendas for our professional benefit. I know there is still a lot more I must continue learning, but what I’ve learned so far has been an eye-opener that is making me rethink how to approach my research and its social aspect.

My project focuses on the social performance of supply chains, and I am seeking to put more emphasis on the “social” part of my research by making it more community-driven. That is why I applied for the fellowship. I am advancing two current projects as part of the fellowship. One relates to increasing food accessibility to vulnerable populations via community-driven freight transportation solutions. I want to bring food closer to people and do it by co-designing solutions with the communities. The second project relates to forming a team to pursue research on enhancing community resilience to extreme weather events for the mobility of people and goods. The fellowship and a Sustainability Next seed grant from BBISS are helping me move forward with this project.

Tamsin Leavy is a self-described “Australian-born Jersey girl” who has lived in, among other places, Montana, Massachusetts, England, Philadelphia, and in an eco-village in Ithaca, New York. Moving around so much made it hard to put down roots, but now that she’s in Atlanta working as the Georgia Tech community garden coordinator, she’s finding that roots are a big part of her day-to-day.

Tamsin started her career working in anthropology and archaeology before pivoting to teaching social studies and history. While working as a teacher in a New Jersey food desert she was stunned at how little access some of the students had to nutritious food. She had grown up around family gardens and fresh grown produce and saw an opportunity to help students access fresh food. With a rekindled love for gardening and plants Tamsin went back to school to earn a horticulture minor from Oregon State University and then sought out ways to combine education and horticulture.

That’s how she landed at Georgia Tech where she is supervising the care of the recently expanded community garden.

The largely student-run garden is located outside of the Instructional Center, or IC, and has grown from a small plot to a collection of 20 raised beds, nine fruit trees, a shed, an outdoor test kitchen, and ADA compliant pathways between the beds. Half of the beds are reserved for student use while the remainder can be leased by any members of the Georgia Tech community. The growing and harvesting seasons don’t align perfectly with the academic calendar, so Tamsin is responsible for making sure the space is tended to whether students are around or not along with offering professional advice on planting and harvesting techniques and sustainable gardening practices.

“We’re focused on making it a space to learn about permaculture and organic gardening,” says Tamsin. “It’s a relaxing space where anybody can come and hang out, eat their lunch, and pick some fruits and vegetables in season. You can come for five minutes, or you can hang out for five hours and participate or just observe. It truly is a space for everyone.”

The bulk of the produce is picked and kept by Students Organizing for Sustainability (SOS) who tend to the garden, but leftovers go to Klemis Kitchen, Georgia Tech’s campus food bank. Occasionally campus chefs pick some produce to be used in cooking demonstrations.

“I’ve always loved being outdoors, having conversations and getting inspired by nature. And let me tell you, these students are inspiring,” says Tamsin. “They want to make a tea garden, with everything from camellias to lemongrass to marigolds. And why not? Let’s do it. They came up with it and we’re going to work to make it happen. It’s amazing.”

Watching students enjoy the literal fruits (and vegetables) of their labor is one of the best parts of the job for Tamsin.

“We had 30 students harvesting sweet potatoes we grew last fall, and they all took home as many as they wanted. We had wheelbarrows full. They all shared pictures of the dishes they made with them. It’s so rewarding to see them get excited about food they grew themselves, and to share that excitement with friends and family.”

Along with the Community Garden Tamsin also advises the SOS students who take care of the rooftop garden on the Kendeda Building, where they are growing cabbage, broccoli, cauliflower, blueberries, and more. They also plan to add more pollinators to make the rooftop more hospitable for the resident bees.

“Every day I get to talk to really smart students who love nature and are eager to learn more about sustainability,” says Tamsin. “It’s an amazing job. These students really care. I’m getting older and I don’t care as much about what my future looks like. But I want these students to have a bright future and for their kids to have bright futures. If I can help them by passing along my knowledge, that’s amazing.”

Georgia Tech unveiled its first Climate Action Plan (CAP), an actionable road map for halving Institute emissions by 2030 and reaching net-zero emissions by 2050. It provides strategies for mitigation, adaptation, climate education, and research, while finding equitable, cost-effective solutions.  

The CAP is a deliverable of Sustainability Next, Georgia Tech’s 10-year strategic sustainability plan, and it is aligned with the United Nations Sustainable Development Goals, the Institute’s strategic plan, and the Comprehensive Campus Plan.  

“As one of the world’s leading research universities, Georgia Tech has the opportunity, and the obligation, to create and share solutions that can help curb climate change and mitigate its harmful impact on our planet and our lives,” said President Ángel Cabrera. “Our Climate Action Plan is bold and ambitious, aiming for 100% clean ground transportation by 2030 and 100% clean energy by 2050. These goals are not easy, but they reflect the seriousness of the challenges before us.”    

The CAP was led by Georgia Tech’s Office of Sustainability, with engagement across the campus community. The CAP Advisory Task Force, comprising experts and Institute leadership, helped guide the effort. Nine working groups in key focus areas developed climate action strategies, and additional stakeholder outreach with students, staff, faculty, and the Atlanta community took place at workshops, events, town halls, and webinars.  

The plan’s nine focus areas and guiding principles are:  

1. Community, Equity, and Accessibility: We seek to ensure that fair and just climate policies and strategies are in place at Georgia Tech and that they prioritize affordable climate change solutions that support our internal and external community. 
2. Building Energy: We are committed to reaching net-zero emissions by 2050.  
3. Renewable Energy and Offsets: We prioritize clean energy technologies to eliminate emissions. 
4. Mobility: We optimize campus mobility through a variety of transportation modes that are accessible, affordable, and low- to no-emissions, considering environmental and human health impacts when determining and implementing transit and land use actions.  
5. Materials Management: We support a thriving circular economy that focuses on upstream systems for achieving zero waste, ensures sustainable procurement, and supports our local community.  
6. Water Management: We adapt our water infrastructure to be resilient to the impacts of climate change.  
7. Education: We prepare all students, regardless of discipline, to address climate-related challenges in their personal and professional lives. 
8. Research: We expand support for faculty, staff, and students to advance innovative research and projects to address climate-related issues.  
9. Carbon Sequestration: We leverage the natural and physical resources of our campus to sequester and store carbon dioxide from the atmosphere. 

The plan has 30 strategies for reaching net-zero emissions by 2050 and advancing climate research and education. The most ambitious strategies include: 

• Transition to electrification of combustion-based heating systems. 
• Increase energy efficiency in building operations. 
• Increase on-site renewable energy production, and procure energy generated from renewable and zero-emissions sources.  
• Transition the campus vehicle fleet to zero-emissions vehicles and increase sustainable and affordable commuting options. 
• Implement blackwater reuse systems and increase water efficiency and conversation. 
• Become a Zero Waste campus. 
• Prioritize climate education across Georgia Tech’s curriculum. 
• Identify and shape future climate research opportunities in which Georgia Tech aspires to lead.  

“Georgia Tech is committed to sustainability and the environmental stewardship of our campus community,” said Jennifer Chirico, associate vice president of Sustainability and chair of the CAP Advisory Task Force. “The CAP was developed in partnership with leadership and with our own experts from within Georgia Tech. As we move toward implementation, it will require a whole-community approach, and we will continue to work together to reach our goal of net-zero emissions by 2050.”

Georgia Tech Center for Sustainable Communities Research and Education (SCoRE) senior director, Jennifer Hirsch, presented a paper to a recent National Academies of Sciences, Engineering, and Medicine workshop, Developing and Assessing Ideas for Social and Behavioral Research to Speed Efficient and Equitable Industrial Decarbonization.

The two-day workshop was organized by the National Academies’ divisions of Behavioral and Social Sciences and Education and Engineering and Physical Sciences and the Boards on Environmental Change and Society and Energy and Environmental Systems. The workshop sought to “lay the foundation for a national interdisciplinary social sciences research program to support an efficient and equitable clean energy transition in the industrial sector.” Sponsors included the Alfred P. Sloan Foundation, the Environmental Protection Agency, the U.S. Department of Energy, and the National Science Foundation. It built on the National Academies 2023 publication, Accelerating Decarbonization in the United States: Technology, Policy, and Societal Dimensions.

Hirsch’s paper, “The Crucial Role of Just Process for Equitable Industrial Decarbonization: An Action Research Agenda for Carbon Management and Other Emerging Technologies,” was one of four commissioned by the National Academies. Lead author Hirsch collaborated with five co-authors from across the country. Workshop proceedings will be published in early summer, 2024.

She and four of her co-authors serve as Community Benefit Plan (CBP) leads on Direct Air Capture Hub or CarbonSafe projects funded by the U.S. Department of Energy, and Hirsch and SCoRE are the CBP leads for the Southeast Direct Air Capture Hub, led by the Southern States Energy Board.

SCoRE is a new center at Georgia Tech that grew out of the Center for Serve-Learn-Sustain. Established in August 2023 within the Brook Byers Institute for Sustainable Systems (BBISS), its mission is to engage faculty, students, and staff in long-term, strategic research and education collaborations with community partners, focusing on sustainability in the Atlanta region, the state of Georgia, and the Southeast. Its key research partners are the sustainability cluster of IRIs, including BBISS, the Strategic Energy Institute, and the Renewable Bioproducts Institute.

Josiah Hester likes to build things. Specifically, he likes to build tiny, computerized devices that can be used to help people monitor the environment around them. As a Native Hawaiian he grew up with a passion for sustainability and stewardship of the land. He also found himself drawn to computer programming and how it could be used to create games, graphics, music, and tools. Now he melds those two worlds as an associate professor in Georgia Tech’s College of Computing and Interim Associate Director for Community-Engaged Research in the Brooks Byers Institute for Sustainable Systems.

The idea to apply computer science to sustainability came when Josiah was a college student at Clemson, where he earned his B.S. and Ph.D. in computer science, with his dissertation focusing on low-cost, low-impact, battery-less, and wireless embedded sensing systems. He continued that work as an associate professor at Northwestern, partnering with local tribes in the Great Lakes region to measure and monitor changes in their local environments that they had been experiencing for years. Those projects sparked Josiah’s passion for community engagement based on long term relationships.

The length and depth of community partnerships are vitally important to Josiah. “We want our faculty, researchers, students and staff to be able to work effectively with communities on these important climate resilience opportunities and make sure that those relationships and the ways that we work together are sustaining and nurturing for each party,” he says.  The last thing he wants to see is a team of researchers dropping in on a community, conducting a quick research project without getting to know the local needs and challenges, and then leaving a few months later never to be heard from again.

“Both parties bring assets to the table that are critically important. Our researchers have specialized skills and interests that allow them to solve complex problems. The local communities often have very in-depth knowledge of their own environment and the changes that are occurring, whether it’s air quality, heat impact, sea level changes, or water scarcity. Our goal is to match those skills with communities that can put them to use to bring about positive change.”

Along with matching researchers and communities, Josiah and his colleagues at BBISS keep an eye on available funding sources to make sure projects are properly resourced. Sometimes a small project that starts with a seed grant can turn into something larger with funding from the EPA, USDA or NSF.

“Those major projects can then lead to actionable science that can inform policy and governance,” says Josiah. “And at the same time faculty are advancing their fields and producing publishable work while helping local communities.”

What Josiah enjoys most about his role as Interim Associate Director for Community-Engaged Research, is seeing researchers who have spent their careers figuring out the science of a subject go into the community and apply it in a practical hands-on way that makes an impact. He is also excited by the students participating in the BBISS Fellowship and how they are approaching community engagement.
“My generation of faculty is getting better at engaging, but the way these students approach it is just next level. The future is in good hands.”

Away from Georgia Tech Josiah has his hands full with three kids, three dogs, and a love for surfing that is hard to satisfy on the Georgia coast. He also enjoys cooking, music, and spending time in parks.
