The National Science Foundation (NSF) awarded a syndicate of eight Southeast universities — with Georgia Tech as the lead — a $15 million grant to support the development of a regional innovation ecosystem that addresses underrepresentation and increases entrepreneurship and technology-oriented workforce development. 

The NSF Innovation Corps (I-Corps) Southeast Hub is a five-year project based on the I-Corps model, which assists academics in moving their research from the lab to the market. 

Led by Georgia Tech’s Office of Commercialization and Enterprise Innovation Institute, the NSF I-Corps Southeast Hub encompasses four states — Georgia, Florida, South Carolina, and Alabama. 

Its member schools include:

• Clemson University 
• Morehouse College 
• University of Alabama 
• University of Central Florida 
• University of Florida 
• University of Miami 
• University of South Florida 

In January 2025, when the NSF I-Corps Southeast Hub officially launches, the consortium of schools will expand to include the University of Puerto Rico. Additionally, through Morehouse College’s activation, Spelman College and the Morehouse School of Medicine will also participate in supporting the project. 

With a combined economic output of more than $3.2 trillion, the NSF I-Corps Southeast Hub region represents more than 11% of the entire U.S. economy. As a region, those states and Puerto Rico have a larger economic output than France, Italy, or Canada. 

“This is a great opportunity for us to engage in regional collaboration to drive innovation across the Southeast to strengthen our regional economy and that of Puerto Rico,” said the Enterprise Innovation Institute’s Nakia Melecio, director of the NSF I-Corps Southeast Hub. As director, Melecio will oversee strategic management, data collection, and overall operations​. 

Additionally, Melecio serves as a national faculty instructor for the NSF I-Corps program. 

“This also allows us to collectively tackle some of the common challenges all four of our states face, especially when it comes to being intentionally inclusive in reaching out to communities that historically haven’t always been invited to participate,” he said. 

That means bringing solutions to market that not only solve problems but are intentional about including researchers from Black and Hispanic-serving institutions, Melecio said. 

Keith McGreggor, director of Georgia Tech’s VentureLab, is the faculty lead charged with designing the curriculum and instruction for the NSF I-Corps Southeast Hub’s partners. 

McGreggor has extensive I-Corps experience. In 2012, Georgia Tech was among the first institutions in the country selected to teach the I-Corps curriculum, which aims to further research commercialization. McGreggor served as the lead instructor for I-Corps-related efforts and led training efforts across the Southeast, as well as for teams in Puerto Rico, Mexico, and the Republic of Ireland. 

Raghupathy “Siva” Sivakumar, Georgia Tech’s vice president of Commercialization and chief commercialization officer, is the project’s principal investigator. 

The NSF I-Corps Southeast Hub is one of three announced by the NSF. The others are in the Northwest and New England regions, led by the University of California, Berkeley, and the Massachusetts Institute of Technology, respectively. The three I-Corps Hubs are part of the NSF’s planned expansion of its National Innovation Network, which now includes 128 colleges and universities across 48 states. 

As designed, the NSF I-Corps Southeast Hub will leverage its partner institutions’ strengths to break down barriers to researchers’ pace of lab-to-market commercialization. 

"Our Hub member institutions have successfully commercialized transformative technologies across critical sectors, including advanced manufacturing, renewable energy, cybersecurity, and biomedical fields,” said Sivakumar. “We aim to achieve two key objectives: first, to establish and expand a scalable model that effectively translates research into viable commercial ventures; and second, to address pressing societal needs.

"This includes not only delivering innovative solutions but also cultivating a diverse pipeline of researchers and innovators, thereby enhancing interest in STEM fields — science, technology, engineering, and mathematics.”

U.S. Rep. Nikema Williams, D-Atlanta, is a proponent of the Hub’s STEM component. 

“As a biology major-turned-congresswoman, I know firsthand that STEM education and research open doors far beyond the lab or classroom.,” Williams said. “This National Science Foundation grant means Georgia Tech will be leading the way in equipping researchers and grad students to turn their discoveries into real-world impact — as innovators, entrepreneurs, and business leaders. 

“I’m especially excited about the partnership with Morehouse College and other minority-serving institutions through this Hub, expanding pathways to innovation and entrepreneurship for historically marginalized communities and creating one more tool to close the racial wealth gap.” 

That STEM aspect, coupled with supporting the growth of a regional ecosystem, will speed commercialization, increase higher education-industry collaborations, and boost the network of diverse entrepreneurs and startup founders, said David Bridges, vice president of the Enterprise Innovation Institute. 

“This multi-university, regional approach is a successful model because it has been proven that bringing a diversity of stakeholders together leads to unique solutions to very difficult problems,” he said. “And while the Southeast faces different challenges that vary from state to state and Puerto Rico has its own needs, they call for a more comprehensive approach to solving them. Adopting a region-oriented focus allows us to understand what these needs are, customize tailored solutions, and keep not just our hub but our nation economically competitive.”

If you’ve ever watched a large flock of birds on the wing, moving across the sky like a cloud with various shapes and directional changes appearing from seeming chaos, or the maneuvers of an ant colony forming bridges and rafts to escape floods, you’ve been observing what scientists call self-organization. What may not be as obvious is that self-organization occurs throughout the natural world, including bacterial colonies, protein complexes, and hybrid materials. Understanding and predicting self-organization, especially in systems that are out of equilibrium, like living things, is an enduring goal of statistical physics.

This goal is the motivation behind a recently introduced principle of physics called rattling, which posits that systems with sufficiently “messy” dynamics organize into what researchers refer to as low rattling states. Although the principle has proved accurate for systems of robot swarms, it has been too vague to be more broadly tested, and it has been unclear exactly why it works and to what other systems it should apply.

Dana Randall, a professor in the School of Computer Science, and Jacob Calvert, a postdoctoral fellow at the Institute for Data Engineering and Science, have formulated a theory of rattling that answers these fundamental questions. Their paper, “A Local-Global Principle for Nonequilibrium Steady States,” published last week in Proceedings of the National Academy of Sciences, characterizes how rattling is related to the amount of time that a system spends in a state. Their theory further identifies the classes of systems for which rattling explains self-organization.

When we first heard about rattling from physicists, it was very hard to believe it could be true. Our work grew out of a desire to understand it ourselves. We found that the idea at its core is surprisingly simple and holds even more broadly than the physicists guessed.

Beyond its basic scientific importance, the work can be put to immediate use to analyze models of phenomena across scientific domains. Additionally, experimentalists seeking organization within a nonequilibrium system may be able to induce low rattling states to achieve their desired goal. The duo thinks the work will be valuable in designing microparticles, robotic swarms, and new materials. It may also provide new ways to analyze and predict collective behaviors in biological systems at the micro and nanoscale.

Nature doesn’t waste energy, and nature finds ways to adapt to a changing world. Understanding those two principles led David Frost to his interest in bio-inspired design. Frost, the Elizabeth and Bill Higginbotham Professor in Georgia Tech’s School of Civil and Environmental Engineering, has spent the last dozen years searching for ways to use nature’s efficiency and ingenuity to improve the civil engineering field. His efforts are paying off. In the last year alone, research from his lab has resulted in multiple patent filings, licensing agreements, and product launches — all of which take their inspiration from the biological world.

Many of those research projects have been the subjects of doctoral research by Frost’s students, with support and advisement from Michael Helms, co-director of Georgia Tech’s Center for Biologically Inspired Design (CBID) and the Brook Byers Institute for Sustainable Systems lead for biologically inspired design. The CBID mandate is to encourage researchers to find inspiration in the biological world, where design solutions have been in development for three-and-a-half billion years as life has on Earth has evolved. Building on the concept that nature isn’t wasteful, one of the goals of bio-inspired design is to develop products that are both energy and materially efficient, and therefore more sustainable.

As the subsurface exploration and excavation thrust leader for the National Science Foundation (NSF) Center for Bio-mediated and Bio-inspired Geotechnics (CBBG), Frost focuses on what’s going on below the planet’s surface. His inspiration comes from things like tree roots, earthworms, spider webs, and ant colonies. In fact, ants are what first got him interested in bio-inspired design.

“There are many organism systems that have not been thought of as necessarily the most intelligent systems. But in fact, they are following a set of rules, approaches, or guidelines and are producing things that, in the end, are both energy- and resource-efficient and adaptive,” said Frost. “One of these is ant colonies. We see the hills above ground, but what’s going on below the ground, with the tunnels and chambers, is fascinating.”

Early in his time with CBBG, Frost came across a Florida artist who made metal castings of ant colony structures. Frost acquired some, made more castings of his own, and then built digital models of ant colonies to understand how the structures maintain their strength. He also studied exactly how ants build such complex structures so efficiently.

“They take advantage of capillarity, arching effects, and the strength of spirals,” explained Frost.

Ants dig by carefully and quickly probing each grain of sand or dirt, in the same way a human might test a Jenga piece, before deciding whether it can be safely removed without damaging the tunnel. As a result, ants are extremely energy efficient as they dig, continually removing the least encumbered pieces of material. Based on this information, Frost and his team are exploring ways to improve the effectiveness and energy usage of tunnel-boring machines.

Other bio-inspired projects from Frost’s research that are further along in the development process include building anchors inspired by tree roots, a ground heat-exchange system based on spirals and plant xylem, a geogrid (or stabilization mesh) design based on spiderwebs, a worm-inspired soil probe, and another probe design influenced by a vortex and centipedes that would displace a minimum amount of soil.

“I'm convinced that just about any system in nature we look at will help us think about analogs for things that, as human engineers, we’d like to do — and do better,” said Frost. “The opportunities for inspiration and improvement are endless.”

Take the Root-Inspired Ground Anchor (RIGA), for example. Anchors are an essential element in construction, stabilizing retaining walls and other foundation structures. Traditionally, anchors are straight poles inserted into the ground. Looking at tree roots, Frost wondered if there was a better way. That thought led him to inventing an anchor that can be driven into the ground and then expanded under the surface, similar to the structure of tree roots. The expandable anchor improves load capacity by up to 75% and is about two-thirds as long as a conventional anchor. After years of refinement, the device has been patented, licensed, and is the basis of a startup founded by Ph.D. student John Huntoon.

Frost takes the most pride in the real-world impact of his bio-inspired designs. Since 2023, Georgia Tech has filed, or is in the process of filing, utility patents for five of them. Like the RIGA system, those patents will be available for licensing for commercial use. Companies have already contacted Frost about his heat-exchange and geogrid concepts.

“Civil engineering doesn’t traditionally have a culture of patent-producing research,” noted Frost. “It’s exciting to see these filings and how they can generate energy and enthusiasm for studying natural systems and using what we learn to improve the world. Practical application has always been very important to me.”

Frost is finding that practical application also appeals to the next generation of civil engineers — specifically K-12 students interested in the profession who tour the CBID affiliated labs on campus. The students study nature’s designs and figure out how to apply them, rather than learn traditional construction methods.

“Ants, spiders, and worms are immediately relatable for middle- and high-school students,” Frost said. “They think engineering is all math and science, and that doesn’t sound fun to them. Instead, we show them they can be inspired by anything and then use that to make it about conservation and adaptation and energy minimization. Those are things they are interested in.”

Frost is hopeful that the students of today and tomorrow will continue to take inspiration from nature, enabling humans to adapt to a changing world as effectively as nature has.

Whether it’s developing new products, reducing costs, or increasing accessibility, innovations in manufacturing stand to improve the lives of companies and consumers alike. Georgia Tech recently took another step toward ensuring those innovations make it from lab to market with the launch of a Modular Pilot Scale Roll-to-Roll Manufacturing Facility. 

“As researchers develop new materials, one of the key aspects we’re missing is how to make them at scale. This is a major oversight because if we can’t make them at scale, we can’t transition from basic research to commercialization,” said Tequila Harris, a professor in the George W. Woodruff School of Mechanical Engineering. “With this new facility, we can prove our discoveries beyond lab-scale studies — and can go from materials innovation to product development at scale.”

Led by Harris, the new facility is the result of a partnership between the Georgia Tech Manufacturing Institute(GTMI), the Strategic Energy Institute, and the Woodruff School. As a pilot facility, it will serve as a testbed for scaling up manufacturing research open for Georgia Tech researchers as well as academic, government, and industry partners around the world.

“The larger vision I see at Georgia Tech involves innovation in manufacturing for large-scale industries,” said Georgia Tech’s Interim Executive Vice President for Research Tim Lieuwen at the facility’s unveiling event on Sept. 19. “It’s crucial that we’re innovating in basic science and technology, but we also need to be innovating in large-scale manufacturing.”

Roll-to-roll (R2R) manufacturing transforms flexible rolls of substrate materials, such as paper, metal foils, and plastics, into more complex, transportable rolls upon coating the surface with one or more fluids, such as inks, suspensions, and solutions, which are subsequently dried or cured on the base substrate. Its high yield and efficiency make R2R an ideal method for the sustainable, large-scale production of components for solar cells, batteries, flexible electronics, and separations — all industries that have expanded in Georgia in recent years.

“As a state institution, we’re ultimately here to serve our state,” said Lieuwen, who is also Regents’ Professor and David S. Lewis Jr. Chair in the Daniel Guggenheim School of Aerospace Engineering. “We’re seeing Georgia emerge as the national leader in terms of recruiting corporate investments in this space and in industries that will be served by this facility.”

Roll-to-Roll Innovations

The R2R process is similar to the production of newspapers, where a large roll of blank paper goes through a series of rollers printing text and photos. “The roll-to-roll aspect is the process of using a specialized tool to force fluid onto a moving surface,” says Harris. It’s one of the fastest-growing methods for producing thin film materials — photovoltaics used in solar cells, transistors in flexible electronics, and micro-batteries, for example — at a large scale. 

Harris’s group works to develop novel manufacturing tools, with a particular focus on understanding and improving the dynamics of thin film manufacturing to increase efficiency and minimize waste. Her group is particularly interested in slot die coating, an R2R technique where a liquid material is precisely deposited onto a substrate through a narrow slot. With the new pilot facility, researchers like Harris will be able to take their work to the next level.

“Slot die coating on a roll-to-roll can handle the broadest viscosity range of most coating methods. Therefore, you can process a lot of different materials very quickly and easily,” says Harris. “It’s one of the fastest-growing technologies in the U.S. — and currently, this is the most advanced modular pilot scale facility at an academic university in the United States.”

“Georgia Tech is way ahead of the curve in terms of our facilities,” says GTMI Executive Director and Regents’ Professor Thomas Kurfess. “This will grow our capability in the battery area, membranes, flexible electronics, and more to allow us to support the development of new technologies.”

“As technologies around cleantech continue to advance at an unprecedented pace, pilot manufacturing facilities provide a critical bridge between innovative benchtop research and commercial-scale production and manufacturing,” says Christine Conwell, interim executive director of the Strategic Energy Institute. “We are excited about the opportunities this R2R facility will provide to the Georgia Tech energy community and our industry partners.”
