I am a plant ecologist interested in the effects of climate change on forest communities.
I teach BIOL 0140 (ecology and evolution), BIOL 230 (global change biology), BIOL 323 (plant community ecology), as well as a variety of first-year and senior seminars that explore ecological history, climate change, and land-use change in Vermont. In my research, I use tree rings to understand how changes in climate affect the growth and population dynamics of tree species in Alaska and Siberia. I have collaborated with numerous Middlebury students over the years to study how changes in disturbance regime have affected an old-growth hemlock forest, the Battell Research Forest, in central Vermont. Follow this link to read more about my research in Vermont and Alaska.
