Research Interests

The processes that determine the hydrochemistry and biogeochemistry of high-elevation basins including the storage and release of solutes from the snowpack, biogeochemical modifications of snowpack runoff, nutrient cycling, and hydrologic pathways and residence time. Current projects include the Rocky Mountains, Ecuadorian and Bolivian Andes, and Central Asian areas of Kazakhstan, Kirghizia, and China.
