Flooding dominated the headlines of summer 2025. Atypical storms and rising rivers in the Texas Hill Country washed away an entire summer camp. Glacial snow melt, combined with flash river floods, caused hundreds of deaths in Pakistan. As the Atlantic hurricane season hits its peak, Americans wait to see if another storm may be as unexpectedly devastating as 2024’s Hurricane Helene. 

Flooding can be an existential threat, affecting everything from infrastructure to health. Georgia Tech researchers are developing solutions to monitor and forecast flooding, as well as restore ecosystems to prevent future flooding. These efforts support communities’ resilience in the face of climate change and keep the U.S. secure.

The College of Sciences is pleased to announce Jenny McGuire as the recipient of the Harry and Anna Teasley Professorship in Ecology.

The newly endowed faculty position supports research and teaching that meaningfully advances the understanding and responsible stewardship of species and community dynamics amid evolving ecological interactions driven by global environmental change. 

McGuire, an associate professor in the School of Biological Sciences and the School of Earth and Atmospheric Sciences, was selected for her pioneering ecological research and exceptional teaching efforts.

“Jenny’s creative and fundamental research in spatial and community ecology is helping to position Georgia Tech as a leader in biodiversity and ecosystem conservation,” says Todd Streelman, professor and chair of the School of Biological Sciences. “Her appointment continues a trend in the School to award research endowments to our most promising early- and mid-career scientists and highlights the strong support and generosity of alumni such as the Teasley family.”

Meet Jenny McGuire

McGuire joined the Georgia Tech faculty in 2017 as an assistant professor. She earned a Ph.D. in Integrative Biology from the University of California, Berkeley, and completed postdoctoral research at the National Evolutionary Synthesis Center and the University of Washington.

Her research explores how plants and animals respond to environmental changes across space and time — from the ancient past to modern urban environments to the future. She leads the Spatial Ecology and Paleontology Lab, which integrates paleontological data, ecological modeling, and fieldwork to understand how biodiversity shifts in response to climate change and human development.

“Our goal isn’t just to preserve biodiversity, but also to help it thrive in a changing landscape,” says McGuire.

She plans to use the Teasley endowment to advance wildlife redistribution research in the Southeastern U.S.

“Georgia is a climate change highway,” explains McGuire. “Species are moving northeast toward the Appalachian Mountains, but roads, development, and fragmented habitats often block their paths.”

McGuire believes Georgia Tech is uniquely positioned to lead in this field, thanks to its technological strengths. She and her team will collaborate across campus and the Southeast, implementing cutting-edge biodiversity monitoring to better understand how species experience and respond to environmental changes.

“Conducting this research in urban areas like Atlanta — where green infrastructure can serve as vital wildlife corridors — is especially important,” adds McGuire.

The Teasley Professorship will also support student involvement at all levels. McGuire hopes to build a more connected and proactive research community that brings together students, ecologists, biologists, engineers, computer scientists, and community partners to address biodiversity challenges across the Southeast.

McGuire is a 2024 Cullen-Peck Fellow, a Brook Byers Institute for Sustainable Systems Faculty Fellow since 2023, and an NSF CAREER Award winner. Her long-running outreach program, Fossil Fridays, invites students, families, and community members into the lab to sort and study real fossil specimens.

Looking ahead, she’s eager to explore the possibilities provided by the Teasley Professorship.

“It’s an incredible opportunity to elevate Georgia Tech’s role in shaping how we understand and protect life on a changing planet.”

A legacy of excellence

Harry E. Teasley, Jr. graduated from Georgia Tech in 1959 with a degree in industrial engineering and worked for over 33 years for The Coca-Cola Company. In addition to the many leadership roles he held at Coca-Cola, Mr. Teasley is remembered for pioneering the first Life Cycle Assessment (LCA) to be used in an industrial context. LCA was a pioneering analytical framework assessing environmental impacts of a product's life from "cradle to grave," and it is used across most major industries today. 

The Harry and Anna Teasley Professorship in Ecology is the second Teasley Professorship supporting environmental research at Georgia Tech. School of Biological Sciences Regents’ Professor Mark Hay has held the Harry and Anna Teasley Chair in Environmental Biology since 1999.

Mrs. Teasley provided an official statement regarding the Harry and Anna Teasley Professorships at Georgia Tech:

“It was the intent of my late husband Harry E. Teasley Jr. that the funds he gave to Professor Mark Hay at Georgia Tech would be to support excellence in the field of environmental biology and to provide him with the freedom to study any concept, hypothesis, or organism that his experience-honed intuition guided him to.  

With time, Professor Hay has proven to have been a very worthy choice and has made my late husband and I very proud through the breadth and depth of his studies, discoveries, and highest possible awards he has received. Once this was established, and along with the profound esteem both men had developed for each other, there was the wish to leave a legacy beyond the research: the human values and scientific approach to research that Professor Hay has demonstrated from the start.  

Having been the unanimous choice of the evaluating committee, Associate Professor Jenny McGuire seems to be an excellent first recipient, and I am very proud to welcome her as I know my late husband would have been as well. 

I wish her many successes in pursuing and teaching her very promising research, and I look forward to learning about the impact she will have in her field as we have through the years admired Professor Mark Hay’s achievements.

Created in 2024, this program funds new centers that seek to increase the College’s research impact and advance its strategic goal of excellence in research through a focus on novel interdisciplinary areas or discipline-specific topics of high impact. The AI4Science Center is the third initiative to be seeded by this program, following the funding of the Center for Sustainable and Decarbonized Critical Energy Mineral Solutions and the Center for Research and Education in Navigation in 2024.

“The AI4Science Center was selected for its approach, timeliness, organization, and strong support from all six of the College’s schools,” says Laura Cadonati, associate dean for Research and professor in the School of Physics. “Faculty enthusiasm about this initiative reflects the growing importance of AI/ML tools in research today and the desire for more interdisciplinary collaboration in this space at the College and beyond.”

The College of Sciences has named Professor Joel Kostka the inaugural faculty director of Georgia Tech for Georgia's Tomorrow. The new center, announced by the College in December 2024, will drive research aimed at improving life across the state of Georgia. 

“Joel is perfectly suited to lead this new initiative, especially since his research for a number of years has focused on Georgia and the vulnerability of both humans and ecosystems to climate change,” 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. “I look forward to seeing how Science for Georgia’s Tomorrow takes shape and evolves under his thoughtful leadership.”

“I believe that my experience in research administration and in leading multidisciplinary research programs, along with the focus of my research on the vulnerability of Georgia’s communities to climate change, have prepared me well for this role,” says Kostka, who is the Tom and Marie Patton Distinguished Professor and associate chair for Research in the School of Biological Sciences with a joint appointment in the School of Earth and Atmospheric Sciences. “I am excited about the opportunity to lead the center as its inaugural director.” 

Kostka’s appointment will begin on May 1, 2025. 

Championing science in Georgia

Georgia's Tomorrow was created to foster research related to the health and resilience of Georgia’s people, ecosystems, and communities. Specifically, it will serve to boost research collaboration across the Institute, pave the way for public-private partnerships, and expand opportunities for Georgia students and communities to engage with Institute research. 

Among Kostka’s first tasks as faculty director will be the development of the center’s strategic plan and the completion of two dedicated cluster hires from within the College of Sciences’ six schools. 

Meet Joel Kostka

Kostka is known for bridging biogeochemistry and microbiology to elucidate the role of microorganisms in ecosystem function. He has emerged as an international leader in ecosystem biogeoscience, providing a quantitative predictive understanding of how ecosystems function as well as determining the mechanisms by which climate change alters ecosystem resilience. He partners with a variety of stakeholders to conduct research on the restoration and adaptive management of coastal ecosystems in Georgia.

Kostka has also served as the PI of a range of multidisciplinary research projects focused on environmental change as well as scientific advisory boards including Georgia Tech’s Strategic Energy Institute, the NSF-funded Plum Island Estuary Long-term Ecological Research program, and the Johnston Center for Coastal Sustainability on Bald Head Island.

Kostka received a B.S. in Biology from Western Illinois University and a Ph.D. in Marine Science from the University of Delaware. Prior to joining Georgia Tech in 2011, he was a professor at the Department of Oceanography and Associate Director of the Institute of Energy Systems, Economics, and Sustainability at Florida State University.

Initial support for Georgia Tech for Georgia’s Tomorrow is generously provided by the College of Sciences Betsy Middleton and John Clark Sutherland Dean's Chair fund. Cluster hire funding has been awarded by Provost Steven W. McLaughlin. The initiative will also seek funding from state, national and international organizations, private foundations, and government agencies to expand impact. Philanthropic support will also be sought in the form of professorships, programmatic support for the center, and seed funding.

Georgia Tech for Georgia's Tomorrow initially launched under the working name Science for Georgia's Tomorrow (Sci4GT). 

Effective January 1st, Gregory Sawicki will serve as interim executive director of the Georgia Tech Institute for Robotics and Intelligent Machines (IRIM). Sawicki is a professor and the Joseph Anderer Faculty Fellow in the George W. Woodruff School of Mechanical Engineering with a joint appointment in the School of Biological Sciences.

“Professor Greg Sawicki will make a great interim executive director of IRIM. He brings experience with robotics and collaborative research to this role,” said Julia Kubanek, professor and vice president for interdisciplinary research at Georgia Tech. “He'll be a strong partner to faculty, students, and the EVPR team as we explore the future of IRIM and robotics over the next several months."

Sawicki succeeds Seth Hutchinson who will be taking a new position at Northeastern University in Boston. Hutchinson, professor and KUKA Chair for Robotics in Georgia Tech’s College of Computing, has served as executive director of IRIM for five years. During Hutchinson’s tenure as executive director, IRIM expanded its industry outreach activities, developed more consistent communications, and grew its faculty pool at Georgia Tech to include a diverse cohort from across the Colleges of Engineering and Computing and the Georgia Tech Research Institute. 

"I am extremely excited to step into this leadership role for IRIM, maintain our research excellence in the foundational areas of robotics, and proactively leverage opportunities to grow across campus and beyond in novel, creative interdisciplinary directions,” said Sawicki. “This will involve new initiatives to incentivize connections with GTRI and other IRI's on campus, to build new industry partnerships, and continue to strengthen the M.S./Ph.D. program in Robotics by engaging with Schools beyond those with a traditional footprint in robotics education and research.”

Sawicki directs the Human Physiology of Wearable Robotics (PoWeR) Lab where he and his group seek to discover physiological principles underpinning locomotion performance and apply them to develop lower-limb robotic devices capable of improving both healthy and impaired human locomotion. By focusing on the human side of the human-machine interface, his team has begun to create a roadmap for the design of lower-limb robotic exoskeletons that are truly symbiotic – that is, wearable devices that work seamlessly in concert with the underlying physiological systems to facilitate the emergence of augmented human locomotion performance.

Sawicki earned a B.S. in mechanical and aerospace engineering from Cornell University in 1999, an M.S. in mechanical and aeronautical engineering from the University of California - Davis in 2001, and a Ph.D. in neuromechanics at the University of Michigan-Ann Arbor in 2007. Sawicki completed his postdoctoral studies in integrative biology at Brown University in 2009.

Sawicki has been recognized for his interdisciplinary research and teaching, recently receiving a $2.6 million Research Project Grant from the National Institutes of Health (NIH) to study optimization and artificial intelligence to personalize exoskeleton assistance for individuals with symptoms resulting from stroke. * Sawicki was also selected as a 2021 George W. Woodruff School Academic Leadership Fellow, and the 2022 College of Sciences Student Recognition of Excellence in Teaching and the 2023 American Society of Biomechanics Founders’ Award for excellence in research and mentoring. Sawicki has also been featured as an expert voice on exoskeletons and human neuromechanics in numerous print and television news releases.

*Joint Award with Aaron Young, Assistant Professor in the Woodruff School of Mechanical Engineering

The School of Physics will launch the new B.S. in Astrophysics program in summer 2025. This new major is the latest addition to the College of Sciences’ academic offerings and responds to increased student demand for courses and research opportunities in astrophysics. A minor in astrophysics will also be offered starting next summer.

According to David Ballantyne, associate chair for Academic Programs and professor in the School of Physics, the new major is unique because it focuses on the future of astronomy and astrophysics, especially in the era of discoveries made by the James Webb Space Telescope and the Laser Interferometer Gravitational-Wave Observatory (LIGO).

“We made a concerted effort when crafting this degree to make it modern and forward-facing,” says Ballantyne. “It is very much focused on the next decade of astronomy and astrophysics, providing a strong emphasis on computational skills, data analysis, and big data.”

The new degree includes coursework on the fundamental physical processes and laws that govern planetary systems, stars, galaxies, and the Universe as a whole. These core topics are complemented by training in computational and data analysis techniques that can be applied to a variety of disciplines. 

For Ballantyne, the degree program should appeal to students who are interested in pursuing careers in space science research as well as those interested in non-research career paths. 

“This program prepares students to solve complex problems in a very quantitative, rigorous way. Such problem solving and computational skills are highly marketable for a range of career paths,” he adds.

The evolution of astrophysics at Tech 

While astronomy coursework and outreach have long existed at the Institute, astrophysics officially began in 2008, when the School of Physics launched the Center for Relativistic Astrophysics (CRA). Today, the Center boasts more than a dozen faculty and research scientists, with expertise spanning high-energy astrophysics, extrasolar planets, gravitational-wave astronomy, and astroparticle physics.

As the CRA’s faculty roster grew, the School expanded its offering of astrophysics courses. A concentration in astrophysics for physics majors was launched during the 2013-14 academic year. A short time later, the School introduced an astrophysics certificate for non-majors. The new astrophysics major and minor — which will replace the concentration and certificate, respectively — reflects a new chapter in the history of astrophysics education and research at Georgia Tech.  

“Most of our peer institutions have an astronomy or astrophysics degree so the creation of this program at Georgia Tech was a natural fit,” says Ballantyne. “Our program fills a critical need considering that there are few options in the U.S. Southeast for students to obtain this type of training at an institution of Georgia Tech’s caliber.”

Declaring the astrophysics major and minor

Current students

Current students can declare the astrophysics major starting next semester, following the standard major change process for undergraduates. The astrophysics minor will be available to all Georgia Tech undergraduates starting summer 2025.  

Incoming students

Astrophysics will be added to the list of majors beginning with the admissions application for Summer 2025 (transfer students) and the 2026-27 academic year (first-year students). 

In the interim, transfer students enrolling for the Spring 2025 semester should follow the standard major change process for undergraduates. Students applying to Georgia Tech for the 2025-26 academic year should select “physics” as their major during the application process and choose “astrophysics” once admitted, during the major confirmation process.
