I have worked in the USGS New York Water Science Center since 1990 studying the effects of acidic deposition and climate change on forest and aquatic ecosystems. Before I joined the USGS, I worked at the University of Maine for three years as an assistant research professor conducting research on the biogeochemistry of lowland spruce-fir forests. I’m co-founder and chair of the Northeastern Soil Monitoring Cooperative and serve as the Technical Director of the USGS Soil and Low-Ionic Strength Water Laboratory in Troy.
I received a B.A. degree in Zoology from the University of Vermont in 1979, a M.S. degree in Environmental and Forest Biology from SUNY College of Environmental Science and Forestry in 1982, and a Ph.D. from Syracuse University in 1987. Since joining the USGS in Troy, NY, much of my work has focused on soil calcium depletion caused by acidic deposition, recovery responses of soils and surface waters to decreasing acidic deposition, nitrogen availability in the environment, and climate change effects on soils and forests.
My academic service includes advising or co-advising more than a dozen students pursing M.S. or Ph.D degrees, co-teaching a four-credit upper level/graduate course entitled “Watershed Biogeochemistry at Rensselaer Polytechnic Institute, and presenting 16 invited seminars at 13 colleges and universities. My scientific service includes serving as an associate editor for the Journal of Environmental Quality for 6 years, a science advisor for the New York State Energy Research and Development Authority for three years, a member of a CENR (Committee on Environment and Natural Resources, under the National Science and Technology Council of the Executive Branch) workgroup addressing the issue of hypoxia in the Gulf of Mexico, October 1997 – September 1999, and a co-author of the U.S.E.P.A. report entitled “ Integrated Science Assessment for Oxides of Nitrogen and Sulfur—Ecological Criteria”, written to provide the scientific basis for EPA’s decision on retaining or revising the current secondary standards for emissions of nitrogen and sulfur oxides.
