Our research interest lies in the field of watershed biogeochemistry. Current projects focus on environmental problems including the impact of nutrients and climate change on aquatic ecosystems. These projects most often require a multi-disciplinary approach which brings to our team specialists in geochemistry, hydrology, stratigraphy, and ecology. Personal special interests include the development and use of isotopic tools (stable and radioactive) and other tracers to supplement the more traditional geochemical techniques utilized in watershed studies.
