Research Interests

My research and teaching interests are focused on the processes controlling hydrologic fluxes in semi-arid regions. My research projects utilize ground-based observations, remote sensing, and computational modeling to obtain comprehensive understanding of hydrological processes; in particular the distribution of snowmelt, soil moisture and streamflow. 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.
