Specialty: Mountain biogeochemistry, snow hydrology, and surface/groundwater interactions.

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 times, particularly surface/groundwater interactions. Current and past projects include the Rocky Mountains, Andes, Central Asian areas of Kazakhstan, Kirghizia, and China, European Alps, and Himalayas. Mark is the PI of the NWT LTER project and a member of a National Research Committee evaluating Himalayan glaciers, climate change, and water security..

Recent Awards: 2008: Denali Award for Recent Outstanding Recent Achievement in Mountain Geography, Mountain Geography Specialty Group (MGSG) of the American
Association of Geographers; 2007-2006: Faculty Fellowship, CU-Boulder; 2006: Residence Life Academic Teaching Award, CU-Boulder; 2006: National Park Service, Intermountain West Annual Award for Research to Support Park Service Resource Management by a non-federal scientist; 2004: ARCUS visiting speaker, Fairbanks and Juneau, Alaska.
