What I do
A major focus of my research is analyzing the performance of hydrological models and improving seasonal forecasting for various hydrometeorological variables.
I specialize in clustering extreme events, inundation regions, or simultaneous events using machine-learning methods. Throughout my career, I have been coding to determine to what extent floods or droughts are interconnected.
As part of the work at the UFZ, I am involved in the ULYSSES project, which seeks to develop better seasonal prediction systems. The description of the project can be seen here.
