I lead the Watershed Process and Estuary Sustainability Research Group (WPES) in the School of Earth and Climate Sciences. WPES is involved in multiple research projects, including several multi-institutional projects administered by the Sen. George J. Mitchell Center for Sustainability Solutions.
IN THE NEWS….
Coastal Pollution Research Grant awarded (Spring 2019) WPES affiliates have been awarded a new grant from the Maine Water Resources Research Institute to conduct research for development of decision tools related to coastal bacteria pollution. The project builds on previous research led by the Mitchell Center focused on the scientific basis for decisions governing closures of shellfish harvesting areas and beaches in response to bacteria pollution problems. The new work will focus on land-sea connections and estuaries on the Maine coast.

Research Focus and History
My teaching and research focuses on watershed geomorphology with attention to processes that influence the morphology and stability of hillslopes and waterways, and that govern the flux of water, sediment and nutrients in the contemporary landscape. Topics of my past and present research include stream channel morphology and stability, surface flow patterns in headwater drainage basins, watershed sediment budgets, and modern watershed best management and rehabilitation practices. I am particularly interested in projects seeking to identify, quantify and explain changes to landscapes caused by human activities.
My work is inspired by interests in advancing the measurement, description and prediction of environmental impacts across spatial scales ranging from single hillslopes to large watersheds and time scales spanning from a single rainfall event to millennia. I have extensive experience working in the Mid-Atlantic region of North America in collaboration with partners involved with the USEPA Chesapeake Bay Program. I have a joint appointment with the Senator George J. Mitchell Center for Sustainability Solutions and affiliation with the Maine Agricultural and Forest Experiment Station (MAFES).
