Research Interests

My general research interests focus on the behavioral and physiological ecology of fishes. In particular, I am interested in how physiological or behavioral adaptations to local environmental conditions arise, are maintained, and their consequences in a conservation and management perspective. I am also interested in the reproductive behavior of fishes and incorporating behavior, reproductive or otherwise, into conservation and management strategies. My current research is based primarily around two very broad questions: how does the interaction between local adaptation and connectivity effect population structuring in aquatic systems and how does behavior and habitat interact to affect reproductive success in fishes?
