I became interested into paleoclimate and global aspects of climate dynamics. In order to understand the mechanisms behind (paleo-)climatic variability I use numerical models of different complexity in combination with proxy data. My research interests include (i) stability and variability of the ocean's thermohaline circulation, (ii) orbital and tectonic forcing of climate change, (iii) climate-ice sheet interactions, (iv) changes in the hydrologic cycle, and (v) paleomonsoons.
