Research Overview
My laboratory does research on primary producers and the animals that eat them in aquatic ecosystems. I am especially interested in the two-way interactions between algal biofilms and their environment. My laboratory has projects that examine nutrient use and recycling in streams, connections between inland waters and their surrounding terrestrial landscapes, changes in biofilm ecophysiology during succession and development, and carbon stable isotope dynamics in algae. We are also beginning to study the bioenergetics and ecological stoichiometry of invasive Asian carp in an effort to predict their potential impact in the Great Lakes.
