My research focusses on regional climatic changes and approaches to assess these. I am particularly interested in extreme precipitation, its natural variability and its response to global warming. In parallel I have been working on the evaluation of regional climate models. More recently I have become interested in researching how future weather might manifest: will the character of storms, precipitation or droughts change, and what are the underlying processes?
Beyond the purely scientific basic research I collaborate with stakeholders in politics and administration and transfer my knowledge to the general public. I have contributed as lead author to the recent 6th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), and I am a member of the scientific steering group of the Lighthouse Activity My Climate Risk of the World Climate Research Programme. A ranking of Stanford University and Elsevier lists me among the 2% top scientists.
In the BSc and MSc programmes on Environmental System Sciences and Atmospheric Physics and Climate I teach Climate and Atmospheric Dynamics, Climate System and Climate Change, Regional Climate Change, Cloud Physics and Climate Modeling. I coordinate the new MSc programme Climate Change and Transformation Science.
