Biography:

Hello! I’m a graduate student alumni of the Ice Sheets and Climate Group at the University of Colorado Boulder. My research focused on snow accumulation at the surface of ice sheets. I developed numerical models to better understand how snow processes including wind-driven snow redistribution and densification influence measurements of ice sheet mass balance.
