I am a Geomorphologist with wide-ranging interests including isotope geochemistry, surface processes, human-induced landscape change, and rates of erosion. I am particularly interested in working at the interface between active research, education, and science literacy at all levels -- thus my involvement in the Governor's Institutes of Vermont (a residential program for high school science students) and National Science Foundation's (NSF) Career and Distinguished Teaching Scholars (DTS) programs combining research and education.
Professor in Geology and Natural Resources
