Welcome! I am an ecosystem ecologist at Dartmouth College interested in human influence on biogeochemical cycles in terrestrial systems. My emphasis is on understanding how climate change alters plant-soil interactions and the ecology, biodiversity and functioning of soils.
My current research examines carbon and nitrogen cycling in the polar deserts of Antarctica and tundra ecosystems in western Greenland. I am also interested in the relationships between the disciplines of ecology, ecosystem science and environmental law.
Currently, I am a co-principal investigator on the McMurdo Dry Valley Long Term Ecological Research Program. I also serve as the Director of the Dickey Center's Institute of Arctic Studies and their NSF funded graduate program in polar environmental change - the Integrative Graduate Education and Research Traineeship (or IGERT).
