Interests/Description:

My research interests are interdisciplinary and center on mountain and snow hydrology, light absorbing particulates in snow and snow energy balance, remote sensing of the cryosphere, and cryosphere-climate interaction. My research methods combine numerical modeling with laboratory analysis and field/remotely sensed observations. One of my main research trajectories is investigating the impacts of mineral dust and black carbon deposition on snow. In this emerging field my research has focused on filling knowledge gaps in the Western US, where increased dust emission and deposition is relatively new process and changing snowmelt patterns have important implications for water security. A related research trajectory is applying my understanding of snow physical and optical properties to remote sensing retrievals, and I am currently a science team member of NASA-JPL's Airborne Snow Observatory. This work is motivated by the belief that advancing remote sensing technology offers the only practical solution to accurately quantify spatial snow water equivalent and monitor spatial snowpack trends over the complex terrain of mid-latitude mountain snow cover.
