Welcome

I am a climate scientist in the Cluster of Excellence Climate, Climatic Change, and Society (CLICCS) and a member of the Earth and Society Research Hub (ESRAH) at the University of Hamburg. My research bridges the scales from global climate change to its implications for extremes at regional and local scales. I am working with the latest observational and climate model data and apply novel statistical and machine learning methods to better understand the physical mechanisms driving extremes and to translate this knowledge into actionable climate information.

Much of my research focuses on temperature extremes, their description, impacts, and drivers: from the representation of extremes in global climate models to their impact on society at local scales, from the large-scale atmospheric patterns that set the stage for heatwaves to the way we define them in the first place. Some of the questions I’m interested in are: how can we fairly evaluate the ability of models to simulate mean and extreme climate, how can we quantify the uncertainty in future projections, and what can new kilometre-scale models add to the representation of extremes and their impacts? Have a look at my publications for more details.

I am eager to work across disciplines and connect my research to other fields in order to address the complex challenges posed by the climate crisis. I am an enthusiastic advocate of open-access publishing, shared code, and FAIR data (see my open science statement). I equally enjoy taking climate science beyond academia through outreach: talking with the public, contributing to formats like the European Forum Alpbach, and working with schools to spark curiosity about our changing climate.
