Biography: 

Broadly, my research focuses on the fate and transport of chemical constituents at the land-sea interface. Recent research projects have investigated the transport of nutrients to the coastal ocean through submarine groundwater discharge and the impact on water quality and coastal ocean ecosystems. I’ve conducted this type of research all over the world, including Antarctica, North Carolina, Monterey Bay, San Francisco Bay, and the Yucatan Peninsula. I often use natural radiogenic tracers such as radium and radon to model and quantify groundwater and associated inputs. Other recent projects have utilized physical models to predict the influence of land-use practices in agricultural areas on nutrient loading in coastal environments.
