My research is aimed at understanding how hydrological processes affect the transport of dissolved and suspended constituents through catchments and aquifers. Current projects include studies of how dissolved organic carbon is mobilized and transported through catchments and how the riparian zone in a coastal plain stream affects nitrogen fate and transport. The dissolved carbon project is a collaboration with researchers at Stroud Water Research center, Avondale PA and the nitrate project is with my colleagues here, Aaron Mills and Janet Herman.
