I am a post-doctoral researcher in the Global Circulation and Climate group, working within the EU-funded TerraDT project. I am a geophysicist by training, but have worked in the field of climate research since my PhD. In my current position, I am contributing to the integration of an interactive ice sheet model into a coupled high resolution ICON setup. Previously, I have worked on simulating the climate, ocean circulation and carbon cycle after the Marinoan snowball Earth with a fully integrated coarse resolution ESM setup of ICON. Furthermore, modelling sea-level rise and its impacts on coastal communities has become one of my major research interests, while working on the development of a new feedback-based integrated assessment model in the WorldTrans project.
Research interests
- Ice sheets and their contribution to sea-level rise
- Coastal impacts of sea-level rise and possible adaptation pathways
- Feedback-based integrated assessment modelling
- Drivers of ocean carbon uptake and release
- Future ocean carbon uptake in overshoot scenarios, such as SSP1-1.9 and SSP5-3.4-over
- Global climate and carbon cycle dynamics of a snowball Earth

Research Highlights
In my Phd Thesis, I have shown that the ocean plays a major role in the aftermath of the Marinoan snowball Earth. It's dynamic circulation removes any freshwater stratification within a few thousand years. At the same time, the ocean's chemical composition determines the evolution of the supergreenhouse climate, with possible scenarios ranging from a rapid decline to an intensification of the extreme greenhouse conditions.
