I have been a hydrologist with the U.S. Geological Survey since 1985. I hold B.A. and M.S. degrees in geology from the State University of New York College at Geneseo and Ohio State University, respectively. I began my career at the New York subdistrict office on Long Island, where I authored reports on the chemical characterization and movement of a ground-water plume of treated wastewater and on point sources that affect shallow ground-water quality. I have worked at the New York district office since 1989, and have conducted water-resource investigations within Greene, Saratoga, Westchester, Delaware, and Putnam Counties. My pricinpal interests include conceptualization of hydrogeologic systems using a multidisciplinary approach (water chemistry, geophysical techniques, and remote sensing) and ground water/surface water relationships, including the effects of land use on the baseflow chemistry of streams.
