- Professor, Environmental Sciences Initiative
- Professor of Earth and Environmental Sciences, Brooklyn College
Peter M. Groffman, Ph.D. joined the Environmental Sciences Initiative in November 2015. He completed his B.A. at the University of Virginia and his Ph.D. at the University of Georgia. Groffman previously held the position of Senior Scientist at the Cary Institute of Ecosystem Studies.
Groffman’s research focuses on terrestrial biogeochemistry with a focus on nitrogen dynamics, especially gases. Projects have ranged across multiple scales from microbial/molecular scale analyses to field/ecosystem scale measurement of fluxes using geochemical and isotope approaches, to landscape and regional scale work using remote sensing, geographic information systems and simulation models. Much of his research is focused at two National Science Foundation funded Long Term Ecological Research (LTER) sites; Hubbard Brook, New Hampshire and Baltimore, MD.
During his career, he has authored over 300 publications, with more than 85 as primary author. Groffman 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). Groffman is also a professor in Brooklyn College’s Department of Earth and Environmental Sciences.
