Profile

How are ice sheets responding to climate and climate change? 

What are the main processes driving this ice sheet response?

How can we improve the models that represent these processes?

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.
