BiographyStephen is a catchment scientist whose research focuses on how hydrological and biogeochemical processes interact in ecosystems. He earned a BS degree from Susquehanna University, an MS degree from Cornell University, and a PhD degree from the State University of New York College of Environmental Science and Forestry. He started as a research hydrologist with the Northern Research Station of the USDA Forest Service in Grand Rapids, MN in 2007. He researches the effects of nitrogen pollution on ecosystem functions, carbon cycling, sources of Hg in the landscape, understanding how climate variability affects hydrological processes in forests, and quantifying the effects of landscape disturbance on yields of water and solutes from ecosystems across a range of settings in the USA and abroad. He is adjunct faculty at the University of Minnesota, Michingan Technological University, and Bedmidji State University.
