My research interests evolve in time, but at the heart of my work is the desire to understand how ice sheets behave, interact with the Earth’s climate, and their impact on sea level. My work is captured by this word cloud. I use a combination of tools that range from mathematics, models and observations. Models are amazing as they allow to test “what if” questions and put together pieces of the puzzle that ice sheets represent. I work with simple models, but also more complex models for continental ice sheets and climate models.

My favorite projects are community efforts such as the Sea level Response to Ice Sheet Evolution (SeaRISE) and its follow-on effort: the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6). ISMIP6 brings together a consortium of international ice sheet models and coupled ice sheet-climate models to explore the sea level contribution from the Greenland and Antarctic ice sheets. ISMIP6 is a collaboration between ice sheet and climate modelers, along with remote sensing experts for the polar regions. Check out ISMIP6 wiki for a description of the framework, participants and publications.
