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 work sits at the interface of climate extremes, future projections, statistics, and model evaluation, driven by the overarching question: how is global climate changing and what are the implications for extremes at regional and local scales?

Much of my research focuses on temperature extremes, their impacts, and their 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 extremes in the first place. Some of the questions I’m interested in are: how can we fairly evaluate the ability of climate 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.
