The focus of our research group is to study the cryospheric components of the water cycle and their response to climate forcing. In particular, we study the Greenland and Antarctic ice sheets, their contribution to sea level rise and the evolution of the Arctic water cycle in response to climate change.

We use multi-sensor geophysical techniques, especially satellite time-variable gravity (GRACE) and altimetry (ICESAT, ERS, Envisat), as well as passive microwave and GPS, in combination with in-situ data, global climate model outputs and re-analysis data.

Our work has implications for future sea level rise, Earth system modeling and global land water cycle. The impacts are not only scientific but also societal as we are working on developing tools to better predict the regional patterns of sea level rise and we are looking at changes in land ecosystems associated with changes in land hydrology.

We collaborate with other researchers in our department (ice sheet research and hydrology), and at other universities in the US and abroad. Our projects range in scale and complexity from regional-scale studies to continental-scale studies with integrated complex modeling and satellite data sets.
