Activities:
Research:
My research interests focus on the ecology and ecophysiology of aquatic ecosystems. I am interested in the ecosystem scale trophic interactions, population dynamics, and early life history of fish, predator-prey interactions, and the ecology of invasive species with emphasis on mechanisms responsible for successful range expansions. I also pursue questions related to the function of essential nutrients (vitamins, fatty acids, etc.) in aquatic food webs and their role in regulating reproductive success and recruitment of fish.
