Peter Groffman

Peter has research interests in ecosystem, soil, landscape and microbial ecology, with a focus on carbon and nitrogen dynamics. He is chair of the Science Council of the U.S. National Science Foundation-funded Long-Term Ecological Research (LTER) network and a participant in LTER projects in Baltimore (urban) and New Hampshire (northern hardwood forests).  Specific recent research efforts from his group include studies of nitrogen dynamics in urban watersheds, lawns, riparian zones and forests, winter climate change effects on nutrient cycling in forests, calcium/nitrogen/carbon interactions in forests, and the effects of exotic earthworm invasion on soil nitrogen and carbon cycling. Peter was a Convening Lead Author for the 2013 U.S. National Climate Assessment Chapter on Ecosystems, Biodiversity and Ecosystem Services and a lead author for the Second (Wetlands) and Third (North America) Assessment Reports of the Intergovernmental Program on Climate Change (IPCC).
