PhD-project: Antarctic Ice Sheet Dynamics in the Quaternary

My main research focus is centered on the fate of the Antarctic Ice Sheet in a changing climate both in the past as well as in the future.  To improve predictions of future climate and ice sheet changes it is invaluable to take a close up look into the past. In my research I investigate the dramatic evolution of the Antarctic Ice Sheet (AIS) during the last 130.000 years and beyond, in order to shed light on the stability of the West Antarctic Ice Sheet (WAIS) in warm climates (http://onlinelibrary.wiley.com/doi/10.1002/2016GL067818/full), Antarctica’s contribution to sea level variations in the past (http://www.the-cryosphere.net/9/881/2015/tc-9-881-2015.html) and in the future, and to improve the understanding of the climate archive conserved in Antarctic ice cores.
Additionally, as a research analyst in a German science and policy think tank (German Advisory Council on Global Change, WBGU), I investigate the complex interdependencies between changes in the climate system and the future sustainability of human civilization.
