My work

Currently, I am a group leader of the HydroScientific Development (HSD) group the HSD group. In this group, we maintain and further develop the mesoscale Hydrologic Model (mHM) and associated tools. I am currently also a visiting scientist at the European Centre for Medium-Range Weather Forecast (ECMWF) and serve as work package leader and service manager in the Ulysses project funded by the European Copernicus Climate Change program.

Further, I am interested in the representation of hydrologic processes within hydrologic and land-surface models, in particular their parametrization. I evaluate a multiscale Parameter Regionalization technique (MPR), presented first for the mesoscale Hydrologic Model (mHM), inside the state-of-the-art land-surface models.

In the past, I lead the HOKLIM project, which investigated high-resolution climate projection for Europe with a focus on different levels of global warming (i.e., 1.5° K, 2° K, and 3 °K).

In my PhD thesis, I worked on the statistical downscaling of meteorological variables (i.e. precipitation and temperature) from climate models to hydrological models. The goal is to generate synthetic high-resolution fields that have the same statistical properties as observations.
