Our group focuses on the physics of glacier ice and how Greenland and Antarctica respond to climate change. Ice sheets play a central role in the climate system: they store significant amounts of fresh water and are the conveyor belts for transporting snow that accumulates inland back into the oceans. If the current warming of the climate continues, the ice sheets will respond at a yet unknown rate, with unknown consequences for the rest of the climate system. A better understanding of the processes driving these changes is critical to improve projections of sea level rise.

We combine high-resolution numerical modeling with remote sensing and in situ data to improve our understanding of ice dynamics, determine how much Greenland and Antarctica will contribute to sea level over the coming centuries, and how they interact with the rest of the climate system. We use and develop the Ice-sheet and Sea-level System Model (ISSM) to address these questions. Click here for more information about our current projects.
