Sam Simkin is an ecologist with wide-ranging interests. He earned his BA in Biology from Earlham College, followed by an MS in Conservation Ecology and Sustainable Development from the Institute of Ecology at the University of Georgia. In his MS research he studied plant responses to fire and soil disturbances created by pocket gophers. In subsequent work at the Cary Institute of Ecosystem Studies he studied landscape patterns of nitrogen and sulfur deposition. He earned his PhD from the Natural Resources Department and the Biogeochemistry Program at Cornell University, studying wetland plant responses to sulfur biogeochemistry in wetlands fed by groundwater (fens). Most recently, in his post-doctoral research at the University of Colorado he examined continental scale patterns of plant diversity with respect to atmospheric nitrogen deposition, climate, and soil chemistry.
