The key to my research is to understand the role of the physical properties of snow and ice on global climate. I focus on critical physical processes in snow/ice-atmosphere interactions and their influence on the energy and mass balance of cold regions, including the subsequent effects on freshwater resources, ice core records and climate change, and sea ice evolution in the context of climate change. The discrepancy between modelled projections of climate variables and sea-level rise suggests that the physical processes of the cryosphere and their effects are insufficiently understood, which leads to significant uncertainties in climate projections. Improved climate projections are essential for policy and mitigation strategies to address climate change consequences for billions of people. Using newly available measuring techniques and state-of-the-art models, I strive to improve our knowledge of the physical processes of snow and ice, which has a fundamental impact on freshwater resources and the accuracy of climate projections. 

I'm currently working on snow on sea ice (Arctic and Antarctic), the effects of impurities on glacier albedo, and the physical properties of ice cores.
