Kathryn L. Cottingham

Academic Appointments

Dartmouth Professor in the Arts & Sciences
Professor, Department of Biological Sciences
Professor, Ecology, Evolution, Environment and Society (EEES) Graduate Program
Fellow, Ecological Society of America
Editor-in-Chief, Ecology

My research interests 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.

My teaching responsibilities reflect these interests, as my courses involve immersive, hands-on engagement with either biostatistics (Biology 29, EEES 127) or ecological research (Biology 22).
