Glaciology, ice-sheet modeling, climate modeling, sea level change


PhD, Theoretical Glaciology, University College London, 2007

Research Interests

My research interest lie in the broad field of ice sheet and sea level. I study how ice sheets interact with the global climate system and in particular affect sea level change, using a combination of applied mathematics, remote sensing observations and numerical modeling. The numerical models that I use span the spectrum of idealized models to large-scale continental ice sheet models. Key to my work are climate models, since they are key for providing forcing for ice sheet model, such as the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6).
