Portrait of Dr. Jake WilliamsAssociate Professor

Ph.D. Miami University, 2005

Office: SLW 1170
Research Lab: SLW 1360
Phone: (618) 650-2118

Courses Taught: Animal Physiology (BIOL 340), Physiological Ecology (BIOL 467/563), Entomology (BIOL 483).

Research Interests: My approach to research is to integrate molecular, cellular, and organismal level techniques to study how life has evolved to survive stresses associated with extreme metabolism.  In particular, my interests include determining how insects survive the metabolic depression and associated severe cold and desiccating conditions of winter and how oxidative stress may lead to functional senescence and limit lifespan in hypermetabolic insects.

Research Opportunities: Opportunities always exist for highly motivated individuals. For inquiries, please contact me.
