I am interested in how the flow of both water and sediments is impacted by dams and climate change. Therefore, my research focuses on watershed processes, with projects spanning a variety of spatial scales, from chemically tagging sediment sources in the smallest headwater catchments to floodplain processes on major rivers. Current projects include (1) efforts to better predict and understand the impacts of high flow events on water quality in New York City's water supply and (2) plan for the cumulative effects of small dam removals on downstream estuarine systems.
