Biography
My research focusses on the interaction between the ice and snow in the polar regions and the remainder of the global climate system. With my background in meteorology, I am strongly interested in the processes that drive this change, especially in the atmosphere (large-scale atmospheric circulation, atmospheric warming), but also in the snow and ice (surface melt, runoff) and especially these processes that are a combination of the two (albedo-melt feedback, drifting snow, polar clouds, etc.). My tools are climate models that I try to understand & improve by combining observations (in-situ, remote sensing) with knowledge on the physical processes. I am a NWO Veni Grant laureate (2015-2017) and am strongly involved in the Water, Climate & Ecosystems (WCE) initiative as part of the UU strategic theme Sustainability (scientific coordinator). I am an active member of the Land-Ice Working Group of the Community Earth System Model. I am laureate of the InBev-Baillet Latour Antarctic Fellowship (2014-2016) that finances two fieldwork seasons to East Antarctica to measure surface melt on an ice shelf.
