Summary

My prime research interest is understanding how global warming affects the number and intensity of extreme weather events like heat waves, heavy rainfall and persistent droughts. I use a variety of methods, including advanced statistical analyses, climate models and novel machine learning techniques, to gain new insights. Working with high-level stakeholders (e.g. the World Bank) ensures that my research focusses on the most relevant extremes, i.e. those with the highest risks for society. I have authored over 40 peer-reviewed publications, with several in top-ranking journals, the IPCC 5th Assessment Report, 3 World Bank reports and several book chapters.

Recent projects

  1. Globally Observed Teleconnections and their role and representation in Hierarchies of Atmospheric Models (GOTHAM). With an international consortium consisting of seven leading climate institutes, including University of Oxford, IPSL (France) and the Indian Institute of Tropical Meteorology, GOTHAM represents an ambitious research program to gain robust and relevant knowledge of past, present and future climate extremes and variability in vulnerable areas as identified by the Intergovernmental Panel on Climate Change.
  2. Atmospheric circulation and its relation to extreme weather (Sacre-X). Shifts in large-scale circulation patterns can strongly alter the frequency and/or intensity of extremes and can thus have severe humanitarian impacts. Climate change over the last century has already altered some large-scale circulation patterns but the uncertainties are large. This project aims to reduce these uncertainties by providing fundamental insights in atmospheric circulation, its modes of variability, and the link to weather extremes.
