When Mark Prausnitz talks about his work as a professor, researcher, and entrepreneur, one theme comes through clearly: collaboration. 

Prausnitz, a Regents’ Professor, Regents’ Entrepreneur, and J. Erskine Love Jr. Chair in the School of Chemical and Biomolecular Engineering, is this year’s recipient of the Class of 1934 Distinguished Professor Award. 

“While I may be the focal point, it’s not a recognition of me as an individual. It’s a recognition of everything the team has done,” Prausnitz said. “I know how to do some things, but there are many things I don’t know how to do. That’s why working with others matters. You bring people together, fill in the gaps, and solve the whole problem.” 

The “some things” Prausnitz knows how to do have led to revolutionary medical innovation over a 30-year career at Georgia Tech, where he has led transformative work in microneedle drug delivery, launching 10 companies in the process. 

During that time, Prausnitz published hundreds of peer-reviewed papers, was granted dozens of patents, and advanced his work from early laboratory studies into more than 20 human clinical trials. His research has produced multiple FDA‑approved or clinically tested technologies. 

Understanding Prausnitz’s success starts with his approach to engineering in practice. Science may begin with discovery, but engineering, as he describes it, focuses on taking something uncertain and making it work. 

“One of the things that really distinguishes engineering from science is the work of problem-solving to reach an answer,” he said. “You start with something diffuse and figure out how to put all the pieces together. That to me is a hallmark of engineering.” 

That way of thinking took shape early in his life.

Lithium-ion batteries power everything from electric cars to laptops to leaf blowers. Despite their widespread adoption, lithium-ion batteries carry limited amounts of energy, and rare overheating can lead to safety concerns. Consequently, for decades, researchers have sought a more reliable battery. 

Solid-state batteries are less flammable and can hold more energy, but they often require intense pressure to function. This requirement has made them difficult to use in applications, but new research from Georgia Tech could change that. 

The research group of Matthew McDowell, professor and Carter N. Paden Jr. Distinguished Chair in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering, has designed a new metal for solid-state batteries that enables operation at lower pressures. While lithium metal is often used in these batteries, McDowell’s group discovered that combining lithium with softer sodium metal results in improved performance and novel behavior.

McDowell and his collaborators presented their findings in the paper, “Interface Morphogenesis with a Deformable Secondary Phase in Solid-State Lithium Batteries,” published in Science on June 5.

Stackable Solution

Lithium-ion batteries have been the industry standard because they combine compact size, reliability, and longevity. However, they contain a liquid “electrolyte,” which helps lithium ions move in the battery but is also flammable. In solid-state batteries, this electrolyte is a solid material that is less flammable. The challenge is that when the battery is used, the lithium metal in the battery changes its shape, potentially losing contact with the solid electrolyte, which degrades performance. A common way to ensure the metal doesn’t lose contact is to apply high pressure to these batteries.

“A solid-state battery usually requires metal plates to apply this high pressure, and those plates can be bigger than the battery itself,” McDowell said. “This makes the battery too heavy and bulky to be effective.”

The researchers, led by Georgia Tech research scientist Sun Geun Yoon, sought a solution. The solid-state batteries would still require some pressure to function, but they found that by also using a softer metal, less pressure is required. The researchers decided to pair the commonly used lithium metal with a surprising element: sodium. 

“Adding sodium metal is the breakthrough,” McDowell noted. “It seems counterintuitive because sodium is not active in the battery system, but it’s very soft, which helps improve the performance of the lithium.”

How soft can sodium be? In a controlled environment, a person could stick their gloved finger into sodium metal and leave an imprint. 

From Biology to Battery

To understand the enhanced performance of their battery, the researchers borrowed a concept from biology called morphogenesis. This concept explains how tissues or other biological structures evolve based on local stimuli. Morphogenesis is rarely seen in materials science, but the researchers found that the combination of lithium and sodium behaves according to this concept. 

McDowell’s research group has been working on applying morphogenesis to battery materials as part of a project funded by the Defense Advanced Research Projects Agency in collaboration with several other universities. Their battery is among the first viable demonstrations of this concept — effectively, the sodium deforms readily at the low pressures needed for solid-state batteries to function. 

Battery Boon

The possibilities of a viable, smaller solid-state battery are vast. Imagine a phone battery that could last much longer or an electric vehicle that could drive 500 miles between charges. With this in mind, McDowell and his team have filed for a patent for this battery system.

While solid-state batteries still have some way to go before commercial use, results like these could mean that solid-state batteries can compete with lithium-ion. McDowell’s lab continues to experiment with other materials to further improve performance.

Chaouki Abdallah, Georgia Tech's executive vice president for Research (EVPR), has been named the new president of the Lebanese American University in Beirut.  

Abdallah, MSECE 1982, Ph.D. ECE 1988, has served as EVPR since 2018; in this role, he led extraordinary growth in Georgia Tech's research enterprise. Through the work of the Georgia Tech Research Institute, 10 interdisciplinary research institutes (IRIs), and a broad portfolio of faculty research, Georgia Tech now stands at No. 17 in the nation in research expenditures — and No. 1 among institutions without a medical school.  

Additionally, Abdallah has also overseen Tech's economic development activities through the Enterprise Innovation Institute and such groundbreaking entrepreneurship programs as CREATE-X, VentureLab, and the Advanced Technology Development Center. 

Under Abdallah's strategic, thoughtful leadership, Georgia Tech strengthened its research partnerships with historically Black colleges and universities, launched the New York Climate Exchange with a focus on accelerating climate change solutions, established an AI Hub to boost research and commercialization in artificial intelligence, advanced biomedical research (including three research awards from ARPA-H), and elevated the Institute's annual impact on Georgia's economy to a record $4.5 billion.  

Prior to Georgia Tech, Abdallah served as the 22nd president of the University of New Mexico (UNM), where he also had been provost, executive vice president of academic affairs, and chair of the electrical and computer engineering department. At UNM, he oversaw long-range academic planning, student success initiatives, and improvements in retention and graduation rates. 

A national search will be conducted for Abdallah's replacement. In the coming weeks, President Ángel Cabrera will name an interim EVPR.
