INSTAAR Directorate Members

Specialty: Alpine biogeochemistry, hydrology, and snow hydrology.

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.

Outstanding Awards : CU-Boulder Faculty Fellowship, 1999-2000; Fulbright Research Fellowship, 1999; EPA Region VIII Outstanding Environmental Achievement Award, 1998.
