LAS Chemistry associate professors awarded grant for promising and creative new research

September 1, 2023

Two associate professors and their research teams have been awarded the Frontier Science Fund in the College of Liberal Arts and Sciences (LAS) for notable scientific research. Brett VanVeller, associate professor of chemistry, specializes in chemistry peptides, and Wei Le, associate professor of computer science, researches how AI and new technology can be used in the medical research world.

The Frontier Science Fund was created in 2021 to allow LAS scientists to pursue new avenues of high-risk, high-reward research that results in positive societal consequences. The fund was established by alumni Tom (’68 geology, MS ’71) and his wife Evonne (’68 textiles and clothing) Smith.

Developing New Ways to Discover Antibiotics

VanVeller and his research team, including Dr. Krishna K. Sharma as co-principal investigator on the project, are developing ways to modify peptide biomolecules in novel ways. With one senior research scientist, seven graduate students, and two undergraduate students, they have been working on this research for nearly seven years.

VanVeller’s research uses medical chemistry and drug discovery to address the threat of antimicrobial resistance.

“What we are trying to do is invent new ways of making molecules that have never existed before. These new approaches open up classes of molecules with unexplored applications as drugs and therapeutics,” VanVeller said.

With this research, VanVeller and Sharma, an expert in drug design and discovery, are trying to use this new chemistry to address the ever-growing threat of antimicrobial resistance, wherein infections become increasingly difficult to treat because microbes no longer respond to existing therapies. The research presents exciting implications for things such as medical chemistry and drug discovery.

“At first you think ‘OK, this is going to work out’ and then you test the experiment, and it suddenly fails. You have to go back and discover why it’s failing and try to address those failures and come up with a new idea to solve the same problem,” Sharma said.

VanVeller and Sharma are excited about the potential of their research. The Frontier Science Fund will allow them to test out several drug designs that have never been attempted before to generate new hypotheses to target bacterial infection.

“Funding like this is important because a lot of the time big ideas start from small ideas,” VanVeller said. “It’s an important area of research and we’re hoping we can make an impactful contribution.”
