Researcher Profile:

I work on a variety of basic and applied questions within aquatic ecology. My primary focus is currently on the influence of biophysical and anthropogenic factors on ecosystem dynamics in the Great Lakes. This includes ongoing projects exploring 1) harmful algal blooms and hypoxia in Lake Erie, 2) early life history and recruitment dynamics of fish, and 3) ecosystem trends and their drivers using long-term monitoring data (integrated ecosystem assessment). I also am interested in the role of predator-induced phenotypic plasticity and chemical communication in aquatic ecosystems. I believe in using a variety of empirical, modeling, and statistical approaches across subdisciplines to gain a strong mechanistic understanding of ecosystems, so most of my research is collaborative.
