I am a Professor in the Department of Natural Resources and Environmental Sciences at the University of Illinois at Urbana-Champaign.

The research in my lab can be defined as 'ecological physiology' as I combine laboratory and field studies to determine the ecological and physiological mechanisms that control abundance and distribution in freshwater aquatic organisms.

While my research is grounded in basic biology, many of my projects work to generate novel conservation strategies to protect freshwater ecosystems. Freshwater fishes are an ideal model system for this research because their diversity and abundance provides me with opportunity to examine these issues while considering evolutionary and trophic relationships.
