Paul D. Frymier

Associate Dean for Faculty Affairs and Engagement, and Professor


Paul Frymier earned his BS degree Magna Cum Laude (1985) and his MS degree (1987) in Aerospace Engineering from North Carolina State University. Following his MS degree, he served in the US Peace Corps in the Gambia, West Africa until 1989.  He earned his PhD in Chemical Engineering from the University of Virginia in 1995.  His dissertation research included experimental studies and theoretical modeling of subsurface migration and substrate degradation by chemotactic bacteria.

In 1995, Frymier joined the University of Tennessee as an Assistant Professor of Chemical Engineering and was promoted to Associate Professor in 2001. His research projects have included the development of whole cell and enzyme-based biosensors, modeling and reactor design for the bioproduction of commodity chemicals, real-time environmental toxicity monitoring, and cell migration and chemotaxis. His current research interests include the study of microbial fuel cells and biological systems based on algae and cyanobacterial photosynthetic and electron transport systems for the production of electricity and hydrogen.
