About me

After my studies in meteorology and my successful doctorate in 2017 at the Jülich Research Centre and the Rhenish Institute for Environmental Research, I worked on the evaluation of the German emission inventory for trace gases and aerosols using four-dimensional variational data assimilation in my post-doc at the Jülich Research Centre.

I am currently leading the working group on inverse and regional modelling at ICE-3. The focus of my research is on the investigation of the predictability of forecast uncertainties. This includes the estimation of various influence factors on the accuracy of the prediction of trace gas concentrations and how to reduce them. Another focus of my work is the investigation of how changing anthropogenic emissions can favour a change in air quality and how improved air quality can be achieved most profitably.

All work in our group is carried out using the chemical transport model EURAD-IM (EURopean Air pollution Dispersion - Inverse Model).
