About Me

Undergraduate research is an important modality in biology education. I enjoyed doing senior thesis work as an undergraduate at St. Louis University so many years ago. I continue to enjoy engaging students in the lab today.

Research Interests

I examine muscle function during locomotion and feeding. Employing fish as model species, my students and I use integrated research approaches, from whole animal performance to tissue function to gene expression. Currently, my lab is focused on how a small, coastal fish, the rainbow smelt, is able to swim and feed during the extreme cold of the North Atlantic winter.
