Jeffrey A. Lewis

Principal Investigator
Dr. Lewis is an Assistant Professor in the Department of Biological Sciences at the University of Arkansas. He earned a Ph.D. in Microbiology from the University of Wisconsin-Madison, and a B.S. in Biological Sciences from UC-Santa Barbara. His current research focuses on understanding the regulation and diversity of microbial stress responses.

Tara Stuecker

Research Associate
Dr. Stuecker joined the lab in 2013. She earned a Ph.D. in Microbiology at the University of Wisconsin-Madison, studying post-translational regulation of bacterial metabolic pathways in the laboratory of Dr. Jorge Escalante-Semerena. Prior to that, she was a technician at NASA's Jet Propulsion Laboratory, studying microbial diversity of spacecraft assembly facilities. In the Lewis lab, she is working to understand the complex genetic underpinnings of stress cross-protection in diverse yeast strains.
