Jud Ready first visited Beaverbrook Park for an adopt-a-stream event as a graduate student. When he moved to the northwest Atlanta neighborhood, he got involved with improvement efforts at the park. 

“It was a muddy mess back then. Over time, we added an exercise trail, playgrounds, a gazebo, and ball fields, but we didn't have a place where you could just walk through the woods,” Ready said. The problem? A creek prevented easy passage, and the park lacked a bridge to cross it.

Despite receiving a grant from Park Pride, a nonprofit that helps residents improve their parks, Ready realized it wasn’t nearly enough money to build a bridge over the rushing waters. Then Ready, a principal research engineer at the Georgia Tech Research Institute with a joint appointment in the School of Materials Science and Engineering, learned that one of his colleagues was using decommissioned wind turbine blades for bridges.

For eight years, Russell Gentry, a professor in the School of Architecture and a member of the Re-Wind Network, has explored how to upcycle wind turbine blades into functional infrastructure. Re-Wind, an international organization, has constructed two bridges in Ireland, where wind energy is more prevalent. The Beaverbrook bridge is the first in the U.S., but building it hasn’t been a simple copy-and-paste process from across the Atlantic Ocean.

“It's not recycling because we're not taking the material back to its original state; it's really adaptive reuse,” explained Gentry. “Think of it as the difference between wood and paper. You can take a tree and grind it up finely for paper, but if you leave it in its original form, you have wood. It’s a much more capable material from a structural perspective.” 

Like almost everything in America, the blades are bigger than their European counterparts.  The 15-meter blade weighs around 7,000 pounds, so moving it from its first home in a Colorado wind farm to a Georgia public park was no easy feat. With funding from the National Science Foundation, the Department of Energy, and wind turbine manufacturer Siemens Gamesa, Ready and Gentry established a team of a dozen Georgia Tech students, researchers, and alumni to bring the blade to Beaverbrook Park. 

Cayleigh Nicholson (architecture), Sakshi Kakkad (computing and architecture), who both graduated in 2024, and fourth-year civil engineering student Gabriel Ackall made sure the bridge was engineered well and that it complied with city regulations. Nicholson spent a semester surveying Beaverbrook to determine the best path and placement of the bridge. Kakkad developed software to better understand the geometry of the blade and position it in the bridge. Ackall was involved in the design process, working with the foundation contractor, Cantsink, to calculate stresses and deflections in the BladeBridges.  

“We’ve essentially had to design the entire structural system of the bridge from scratch, as existing building and bridge codes do not have much information about either the composite materials used in wind turbine blades or in adaptive reuse for new construction,” Ackall noted. “We used advanced modeling software combined with the knowledge we’ve gained from over a half dozen years of wind turbine blade testing and prototyping to make the bridge a reality and ensure their safety.” 

Even alumnus Tierson Boutte, CE 2002, who owns the tree company Boutte Tree, helped make the installation possible. “We’re grateful to be able to give back to the community by pruning the trees for the crane to be able to lift the turbine blades,” he said. 

On a sunny day in mid-March, the bridge was installed with a combined crew of 16 from Chappell Construction, led by alumnus  Wade Chappell, IE  2000; Williams Erection Company, owned by alumnus Art Williams, CE 1983; and ironworkers from Local 387. Finally, with a little help from an unusual source, a neighborhood can fully enjoy its park.

In late February, the Brook Byers Institute for Sustainable Systems (BBISS) hosted the Sustainability Showcase in the Scholars Event Theater in Georgia Tech’s Price Gilbert Library. The two days of panel discussions, keynote speeches, and lightning talks were themed around community, ecosystem, and infrastructure resilience. Researchers, faculty, students, staff, and partners demonstrated how they are innovating and collaborating to build a more resilient future as the world rapidly changes.

The first day's morning session framed the discussion with three panels. The first focused on Georgia Tech’s resilience plan, discussing institutional strategies to ensure campus operations and support for the Georgia Tech community in the face of external disruptions. The second panel broadened the discussion to explore resilience strategies for the city of Atlanta. The third panel further expanded the scope to consider the resilience of the southeastern United States.

One of the highlights of the showcase was the alumni keynote address by Laura Solomon, ISyE 2000, co-founder of Tybee 

Oyster Company. Solomon told her inspiring story about the recent origins of the ocean aquaculture industry in Georgia and the connection between oyster aquaculture, local community engagement, education, and bolstering a thriving and resilient coastal ecosystem. She emphasized the importance of her company’s sustainable practices and shared her experiences in pioneering Georgia's first floating oyster farm. Solomon also underscored the importance of oysters in helping Georgia’s coasts become more resilient against storms, sea level rise, erosion, and poor water quality.

A mainstay of the Sustainability Showcase are the lightning talks, where students, campus organizations, and researchers can bring attention to their sustainability initiatives and research.  Lightning talk sessions were interspersed throughout both days of the event and helped to bring a broader contingent of the sustainability community together to learn about each other’s work and make valuable connections.

The last panel discussion of the day, on ecosystem resilience, was moderated by Jenny McGuire, associate professor in the School of Biological Sciences. “A better understanding of ecosystem resilience not only helps us to preserve species for future generations,” she said, “but gives us perspective on how we can better inhabit the ecosystems we rely on for our own well-being.” The day concluded with a networking reception.

The second day began with a panel on infrastructure resilience, which explored the links between infrastructure elements in the built environment, how they interact with each other, and how our communities can recover from disruptions to infrastructure functions.

The event wrapped up with a visioning “unconference” session, where members of the Georgia Tech sustainability community gathered to share their thoughts on how the concept of resilience blends with sustainability, and how Georgia Tech can advance research and education to prepare our communities for the upcoming challenges facing us. It is anticipated that the participants in the unconference will collaborate on a white paper to document what was learned and shared at this final session. 

"The Sustainability Showcase exemplified Georgia Tech's commitment to resilience at every level,” said BBISS Interim Director Beril Toktay. “By bringing together diverse perspectives from our campus, city, and region, we created a space for both innovative thinking and practical collaboration. As we navigate increasingly complex sustainability challenges, this collective approach will be essential in building the resilient communities and systems our future requires."

The 2025 Southeastern Energy Conference, Georgia Tech’s annual student-led energy and sustainability conference, took place from Feb. 28 to March 1, 2025.

Students in Matthew Oliver’s economics of environment and international energy markets classes likely don’t have a clue about his unusual journey to the lectern: “I was bent on being a rock and roll musician from the time I was 16, and so I ended up dropping out of the University of Memphis after just three semesters,” says Oliver, an associate professor in the School of Economics at the Georgia Institute of Technology. “I was on tour for eight years — and I was starting to feel burned out.” 

At a crossroads, Oliver decided to end his musical career — a choice he credits with launching him into academia. “I was 28 and wondering what to do with my life, so I reenrolled in college and discovered economics.”  With a longtime love of the environment and growing concern for the climate, says Oliver, “I grew fascinated with solar power and other renewables and the new markets emerging around them.”  

Today, his work in energy and environmental economics has implications for policies shaping the energy transition, from subsidies for rooftop solar to the expansion of battery storage. 

“The current frontier of energy economics is electricity and renewables, and these are areas I am passionate about,” he says. 

PVs and amped up electric use 

One of Oliver’s core research thrusts is the solar rebound effect (SRE). This phenomenon involves a quirk of human behavior: When people install solar photovoltaic (PV) panels on the roofs of their homes, they often consume more electricity. “The introduction of solar energy does not perfectly displace grid-supplied energy, but instead reduces demand for grid-supplied energy on a less than one-for-one basis, because the household increases its total electricity consumption,” says Oliver. The bottom line: Solar PV systems may not lead to as much carbon emission reduction as anticipated.

Chemical and biomolecular engineers at Georgia Tech have developed a plug-and-play platform for detecting protein biomarkers of disease that’s simple, flexible, and easy to use without costly lab equipment.

Their work could unlock a new wave of at-home testing options and provide new diagnostic capabilities in parts of the world where medical resources are scarce.

The testing platform fills a gap in using cell-free synthetic biology for disease detection. Existing cell-free tools have proven effective at measuring DNA, RNA, and other small molecules, but not proteins. That’s an important advance because proteins in viruses or bacteria tend to change less than the DNA or RNA sequences that encode those proteins. They’re also easier to detect since they can be found on the outside of cell walls or free-floating in biofluids. 

“Diagnosing disease and democratizing medical care by putting it into the public's hands has great potential. You can have a big impact on a lot of people,” said Mark Styczynski, William R. McLain Endowed Professor in the School of Chemical and Biomolecular Engineering.

“I think about that a lot in terms of the developing world, but also there's a lot of healthcare inequality even in the United States. Studies have shown your ZIP code can determine your life expectancy. You can think about people in sub-Saharan Africa or people in rural Appalachia all benefiting. They’re among those who need more access to low-cost tools.”

Styczynski and a group of researchers led by former Ph.D. student Megan McSweeney presented their test in late February in the journal Science Advances.
