A Georgia Tech-led project advancing coastal resilience and ecosystem restoration has been selected for the inaugural Climate Resilience Fund cohort, awarded by Revive & Restore. The award is one of ten in a new $3.4 million fund to leverage genetic rescue for marine and coastal ecosystems under threat from climate shifts.

Led by Joel E. Kostka, Tom and Marie Patton Distinguished Professor and director of Georgia Tech for Georgia’s Tomorrow (GT²), the research effort will help restore coastal salt marshes through AI-enabled micropropagation and developing probiotics for plants. It is the only salt marsh-focused effort funded nationally in the cohort.

The award supports both the development of more climate-resilient salt marsh plants, as well as new capacity for coastal restoration in Georgia — an effort that aligns closely with GT²’s mission to connect research, innovation, and community needs to address critical environmental and community challenges.

Healthy Coasts

Salt marshes are among Georgia’s most important natural resources, helping buffer communities from storms, support fisheries, and sustain coastal economies. Yet the state currently lacks a reliable source of salt marsh seedlings needed for large-scale restoration.

The funded project addresses that gap by advancing the production of hardier marsh plants and laying the groundwork for a broader restoration economy.

“The opportunity here is to build something that doesn’t currently exist in Georgia — a scalable, science-driven supply of salt marsh plants for safer, healthier coastal communities and ecosystems,” Kostka says. “By combining biotechnology, ecology, and partnerships across the region, we are accelerating coastal resilience while supporting long-term environmental and economic benefits.”

Kostka will work with project co-researchers Else-Marie Ulrika Egertsdotter (Georgia Tech Renewable Bioproducts Institute) and Caitlin Petro (Georgia Tech Biological Sciences), Heather Joesting (Georgia Southern University), Emily Coffey and Lauren Eserman-Campbell (Atlanta Botanical Garden), and Sydney Williams (University of Georgia and Georgia Sea Grant) — along with several anticipated regional partners, including University of Georgia Marine Institute, GA/SC/NC Departments of Natural Resources, Southeastern Plant Conservation Alliance, and Bald Head Island Conservancy.

The team will create a “Climate-Ready Spartina Toolkit” with automated plant tissue culture, AI-based screening tools, a culture collection that serves as probiotics for plants, a seed bank and library of preserved plant materials, step-by-step instructions for successful growing, and ready for regional deployment.

The project also continues the evolution of Kostka’s collaborative research Egertsdotter and the Georgia Tech Renewable Bioproducts Institute. “RBI shares the goal of using biotechnology to produce climate-resilient plants that benefit society,” Kostka says. “Their expertise in plant tissue culture and automation make this work possible. It also is a great example of collaboration between GT Sciences and Engineering — the automation of plant tissue culture was developed by mechanical engineers in RBI.”

Regional Resilience

The new award builds on growing momentum for Georgia Tech for Georgia’s Tomorrow and its expanding network of collaborators focused on coastal resilience. Based in the College of Sciences, GT² is designed to align discovery science with technological innovation and data-driven tools to deliver practical solutions for communities across the state.

In April, GT² launched a formal research fund and partnership with the Bald Head Island Conservancy (BHIC), connecting Georgia Tech researchers with BHIC’s Johnston Center for Coastal Sustainability in North Carolina to advance shared work in coastal sustainability, ecosystem health, and environmental resilience.

The partnership combines BHIC’s applied, field-based conservation work with Georgia Tech’s strengths in technological innovation and data analysis, creating new opportunities for graduate research, community engagement, and real-world implementation.

Better Together

These “all hands on deck” approaches reflect a broader strategy to scale tangible solutions across regional ecosystems by connecting researchers and partners with community stakeholders.

“Together, we hope these projects will demonstrate that genetic rescue is a powerful lever for the blue carbon ecosystems that underpin both ecological and human communities in the face of climate change,” said Liv Liberman, Director of Ocean and Climate at Revive & Restore and program manager for the Climate Resilience Fund.  

The efforts reflect GT²’s goal of creating pathways from research to implementation, working across sectors to deliver measurable outcomes for the southeastern environment and its communities.

“This award recognizes the kind of integrated, real-world research that GT² is built to deliver,” says Kostka. “We’re bringing together researchers, agencies, and community partners to move from science to scalable solutions — especially along southeastern coasts, where the need is urgent and the opportunities are significant.”

The Georgia Tech Master of Science in Human-Computer Interaction (MSHCI) program has another reason to celebrate as it prepares to mark its 30th anniversary later this year.

The Board of Regents of the University System of Georgia awarded the program the 2026 Teaching Excellence Award for Department or Program.

MSHCI program director Dick Henneman and assistant director Carrie Bruce received the award on May 12 during a Board of Regents (BOR) meeting.

Henneman has served as director of the program since 2015, and Bruce has served as assistant director since 2014. The program began in 1996 and has since expanded to be offered by four Georgia Tech schools:

• Interactive Computing
• Industrial Design
• Literature, Media, and Communications
• Psychology 

“As we put our award submission together, it was nice for us to reflect on all our hard work and to understand the impact this program has had on students,” Bruce said. “We recently surveyed alums, and so many said they were thankful for the way this program shaped their careers.”

Under the leadership of Henneman and Bruce, the program has achieved a 99% graduation rate, with about 60 graduates per year, up from about 30 since 2015. Henneman said the program has become one of the most competitive of its kind in the world, with an admission rate under 10%.

“We have some incredibly qualified students who are a part of the program,” he said. “We’ve had a number of graduates move into design management positions, and some have started their own companies.”

Henneman and Bruce said that one thing that distinguishes Tech’s MSHCI program is its close partnerships and alignment with industry. The program has an industry advisory board that keeps students informed about the skills companies value.

“We adapted our core classes quite a bit to ensure that they weren’t just getting the academic version of HCI methods,” Bruce said. “Our program is practical and focuses on what they are going to do when they get into industry.”

Though the program continues to grow, Henneman says it has maintained a sense of community among students, which he says is another thing that sets it apart. Many alumni keep in touch and return to offer industry advice, critique resumes, and conduct mock interviews with current students.

“A lot of times graduate school can be all about the individual,” he said. “As we prepare students to go work in industry, it’s all about collaboration and the people you’re working with and learning how to work on teams.”

Georgia Tech had 21 faculty and researchers recognized in the 2026 Regents Awards. From the College of Computing, Santosh Vempala was named a Regents’ Professor, while Srinivas Aluru and Ellen Zegura had their Regents’ titles renewed.

Researchers have come close to simulating space environments in Earth labs, but the combination of extreme thermal swings, complex cosmic radiation, and sustained microgravity that spacecraft experience make it impossible to capture the real thing perfectly.

Now, in a project led by the Georgia Tech Research Institute (GTRI) in collaboration with the Georgia Institute of Technology (Georgia Tech) researchers are closing the gap between Earth-based simulations and the true space environment by sending experimental materials to the International Space Station (ISS) for several months of in-orbit exposure. In a rare chance for space research, where most hardware is either left in orbit or burns up on reentry, they are getting those samples back for detailed analysis on Earth.

The materials are set to launch to the ISS in the near future as part of the Materials International Space Station Experiment 22 (MISSE-22), a testbed attached to the outside of the station. Mounted on the forward-facing side of the ISS to ensure predominant exposure to highly corrosive atomic oxygen, the test samples will spend several months enduring the extreme temperatures, radiation, and reactive environment of low Earth orbit. The team is testing a selection of lightweight, research-grade polymers designed to survive these harsh conditions. Once the samples return to Earth, engineers will examine how they held up and use that data to enhance the strategic of future satellite constellations.

This project represents a collaboration across government, academia, and industry, bringing together GTRI, Georgia Tech, the Air Force Research Laboratory (AFRL), the University of Texas at El Paso (UTEP), a California-based R&D firm Hedgefog Research Inc., and DuPont de Nemours, Inc. The research is also supported by Aegis Aerospace, which owns and operates the MISSE Flight Facility platform aboard the ISS.

Why Space is So Hard on Satellites 

Harsh conditions in low Earth orbit — the region of space extending from approximately 100 miles to over 1,000 miles above Earth, where many satellites and the ISS travel — can darken, roughen, and weaken spacecraft surfaces over time. That damage shortens satellite lifetimes and requires engineers to add extra layers of protection, increasing overall logistical burden and mission costs. 

Optimizing material durability is a strategic necessity, explained Elena Plis, a GTRI senior research engineer and principal investigator for the project, because every additional unit of shielding increases the cost of getting to orbit. To design lighter, more resilient materials, researchers need to examine how they degrade in a true space environment. However, most hardware is built for a one-way trip — designed to operate in orbit and then burn up on reentry, taking that valuable material data with it.

“The beauty of this type of experiment is that the materials return to Earth,” said Plis, who is also an affiliate of the Georgia Tech Space Research Institute. “For many missions, stuff is sent up and never seen again. Being able to test returned samples from real space conditions is unique, and I can’t stress enough how exciting that is for us.”
 

A New Generation of Polymers Head for Space

Instead of relying on familiar spacecraft materials like DuPont’s Kapton — a tough, heat-resistant polyimide plastic film that has coated spacecraft exteriors since the Apollo era — the team is sending up a set of new, lightweight, research-grade polymers. These materials are designed to improve the survivability of assets against space’s unforgiving elements.

Plis and her collaborators started with dozens of candidate materials they developed. To earn a spot on the MISSE-22, a sample has to be transparent or translucent, so light can pass through it, and researchers can examine how its optical properties change in orbit. The materials also have to be tough enough to withstand intense atomic oxygen exposure without fragmenting, which would create debris near the ISS. In the end, only a select number of the team’s materials made the cut.

The MISSE-22 testbed holds multiple experimental polymers. Instead of standard illumination, the team constructed a custom on-orbit polariscope: LEDs beneath each sample shine polarized light up through the material. A small camera system then slides over the top to capture these highly specific optical changes on a set schedule over the course of several months in space.

Using Light to Reveal Space Strain

Using polarized light and machine learning to rapidly analyze color patterns in the images they receive from orbit, the researchers can track how stress inside each sample changes over time. Periodically, the system will cycle through the materials, and the images will be downlinked to Earth.

When the extended mission ends and the samples return, the team will compare those in-orbit measurements with detailed lab tests on the actual pieces that flew. Without returned materials, they would only have images and sensor data to work from. By testing the same samples in the lab, they can check how accurate the remote measurements really are and refine their methods.

If the materials perform as expected, the results could help engineers design satellites that last longer in orbit without carrying so much protective weight —providing a significant technological advantage in space domain awareness and asset longevity.

Sleep-related breathing disorders, including sleep apnea, affect millions of people worldwide but frequently go undiagnosed. One major barrier to diagnosis is the test itself.

Traditional sleep monitoring systems often rely on bulky equipment and nasal cannulas — small tubes inserted into the nostrils to measure airflow. While effective, these systems can be uncomfortable, intrusive, and difficult to tolerate overnight, limiting their use for long-term monitoring at home.

Now, researchers led by W. Hong Yeo, Peterson Professor in Pediatric Research at the George W. Woodruff School of Mechanical Engineering, have developed a soft, wireless nasal patch that could offer a more comfortable alternative for monitoring breathing during sleep.

The technology, described in a recent study published in Proceedings of the National Academy of Sciences (PNAS), uses ultrathin, skin-like wearable electronics to detect subtle movements of the nose caused by breathing without tubes, wires, or direct airflow measurements.

In the summer of 2019, Caroline Howell came to Georgia Tech for the first time to participate in the NNCI Research Experience for Undergraduates (REU). As a student at Troy University in Alabama, Howell was looking to broaden her research horizons.

“I went to a smaller university because I came from a very, very small town,” she said. “I did some research there, but we didn’t have a lot of equipment or resources.”

During the 10-week program, undergraduate students live on campus and conduct research in faculty labs with mentorship and access to advanced facilities. The program also prepares students for graduate studies and STEM careers through professional development, research communication training, and opportunities to present their work.

“I applied to the REU at Georgia Tech. And when I got in, I was super excited because Georgia Tech is a big deal,” she said.

That summer didn’t just expand her lab experience; it reshaped her career trajectory.

As a physics major, Howell had never been exposed to materials science, nanotechnology, or cleanroom environments before arriving in Atlanta. That summer marked her first time using advanced equipment, including scanning electron microscopes (SEMs), and working hands-on in Georgia Tech’s cleanroom facilities. 

Her project focused on aluminum alloys, testing their strength and fracture behavior under simulated harsh conditions such as saltwater and heat. The research explored how lightweight, affordable materials like aluminum could be made stronger for applications such as shipbuilding. 

The experience opened a door for Howell. 

“It inspired me to go to grad school for materials science,” she said. 

After completing her undergraduate degree at Troy University, Howell pursued graduate studies in materials science at the University of Colorado Boulder, where she earned her master’s degree. 

Her REU experience gave her a technical advantage early in her career.

“In my first job, I worked with the same machines I used at Tech because I already had experience with them,” she said. 

Today, Howell is back at Georgia Tech. This time not as a student, but as an industry researcher using the Institute’s cleanroom facilities as part of her full-time job. 

She conducts advanced lithography and SEM analysis in the same facilities, expanding far beyond what she was able to do as an undergraduate. Still, she credits the REU with giving her a strong foundation.

“I came in already knowing how to do some things, and it’s just kind of cool to be back in the same space I was in years ago,” Howell said. 

In a full-circle moment, the place that first introduced her to materials science is now part of her professional experience.

For Howell, the impact of the REU extended well beyond lab work. The REU provided her technical training, exposure to a new discipline, and the confidence to pursue graduate education. It connected her with mentors who supported her next steps and introduced her to equipment she would later use professionally.

For students considering an REU, her advice is simple:

“Do it.” 

Sometimes, a single summer can shape an entire career — and even bring you right back to where it all began.
