Due largely to human activities associated with food and energy production, the world is experiencing an unprecedented mobilization of nutrients such as nitrogen (N) and phosphorus (P). A substantial portion of this mobilized N and P flows into streams and rivers, and eventually down to coastal waters. Along the way, these these nutrients alter ecosystems, biogeochemical cycling, and the balance of atmospheric greenhouse gases.
Our research group uses experimental, observational, and modeling approaches to elucidate processes governing the mobilization, transport, transformation, and ecosystem/biogeochemical impacts of land-based N, P, and other bio-active elements. Descriptions of past and ongoing research projects can be found here.
