Research Abstract
Employ novel geophysical methods and satellite remote sensing techniques to understand the physical processes governing ice sheet and high mountain glacier mass balance, and the hydrologic cycle of high latitude regions, with an emphasis on time-variable gravity from the Gravity Recovery and Climate Experiment (GRACE) missions and other geophysical data (satellite altimetry, GPS, climate model outputs, in situ observations).

Study the impact of melting ice sheets and glaciers and ice caps on global and regional patterns of sea level rise using geophysical numerical methods.

Study ecosystem response to climate change and variability in terrestrial water storage combining multiple remote sensing techniques and climate model outputs.
