Kathryn L. Cottingham

Professor of Biological Sciences
Professor and Co-Chair of the Ecology and Evolutionary Biology Graduate Program

My research interests are very broad and include the dynamics of lake plankton communities, linkages between terrestrial and aquatic ecosystems, and the applications of ecological principles to public and environmental health.  Lab members typically work collaboratively on topics of mutual interest using observations, experiments, and models.  Our work often has a strong statistical component.
