“My studies at the University of Kentucky gave me a good foundation in soil and environmental sciences for understanding small watershed biogeochemistry that has underlain most of my professional work experience.”

I am a research hydrologist with the U.S. Geological Survey's Maine Water Science Center. In recent years my research has focused on hydrologic responses to climate change, carbon cycling at larger river basin scales, and on denitrification in wetlands. I have studied hydrologic responses to climate change at a variety of spatial and temporal scales. Together with colleagues in the U.S. Geological Survey I have studied trends in lake and river ice dynamics, stream flow timing, snowfall, and stream water temperature. My experience in this area includes both time series analysis of historical data and projections for changes in hydrologic conditions during the 21st century. I am particularly interested in studying the processes by which climate change influences carbon cycling in terrestrial systems.
My studies at the University of Kentucky gave me a good foundation in soil and environmental sciences for understanding small watershed biogeochemistry that has underlain most of my professional work experience. Studying plant and soil sciences from an agricultural perspective has given me an appreciation for how anthoropogenic modifications of the landscape influence water resource quality and quantity that has been valuable in my professional career.
My advisors and the faculty in Plant and Soil Sciences provided the interdisciplinary professional preparation that gave me the confidence to pursue a career using a foundation in soil, plant, and environmental sciences.
Some of my best experiences were interactions with other graduate students both in and outside of academia. I am grateful for the experiences that I had interacting with my faculty advisors as part of my doctoral field work in the Dominican Republic.
2007 - expert reviewer for the Intergovernmental Panel on Climate Change's Fourth Assessment Report (IPCC AR4) Working Group II for which Rajendra Pachauri (Chair of the IPCC) in receiving his share of the 2007 Nobel Peace Prize acknowledged that all (ca. 3000) contributing authors, co-authors and expert reviewers shared in the award.
