I am a Professor at the City University of New York Advanced Science Research Center and Brooklyn College Department of Earth and Environmental Sciences, and a Senior Research Fellow at the Cary Institute of Ecosystem Studies. I have research interests in ecosystem, soil, landscape and microbial ecology, with a focus on carbon and nitrogen dynamics. Specific recent research efforts 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.
I currently serve on the Scientific and Technical Advisory Committee of the National Ecological Observatory Network (NEON) and was chair of the Science Council of the U.S. National Science Foundation funded Long-Term Ecological Research (LTER) network from 2015 – 2019. He is a participant in LTER projects in Baltimore (urban) and New Hampshire (northern hardwood forests).
I 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).
