Research Interests
I am a physiological ecologist and an aquatic toxicologist. My principle research focuses on fishes living in contaminated environments. Much of my research focuses on agrichemical contaminants, and fish living in Nebraska. The Elkhorn River watershed is of particular interest to me.

The use of fish as environmental sentinel organisms interests me, as aquatic organisms can tell us a lot about water quality. I like mechanism, how things work, and that's the approach we take toward scientific inquiry. I am always looking for student help in my lab, on an undergraduate, M.S. and Ph.D. level, so if these projects appeal to you, contact me!
