My research and teaching interests are focused on the processes controlling hydrologic fluxes in mountainous regions and within the greater Earth system. Improved understanding of these processes is essential for sustainable management of natural resources and for making informed environmental policy decisions. My research projects utilize ground-based observations, remote sensing, and computational modeling to obtain comprehensive understanding of hydrological processes; in particular the distribution of snow and vegetation. Additional projects aim at developing techniques for scaling hydrological processes and for designing ground-based observation networks tailored for integration with remote sensing and modeling. Studies relating fluxes of water, carbon, and nitrogen are also a focus of my current projects - in particular the feedbacks between water availability and carbon cycling in montane forests.
