What drives ice sheet change?  

how do we reduce uncertainty in predictions of Sea-level rise?

WHAT IMPACTS DO CHANGES IN ICE SHEETS HAVE ON OTHER NATURAL SYSTEMS?

Our group works on understanding ice sheet and glacier changes that arise from both natural and forced variability.  Our approach is observation-driven and aimed at unravelling the physical processes that control ice motion and change.  We using a suite of techniques to pursue these goals including ground-based geophysical techniques, remote-sensing observations and numerical models.
