About me

Since March 2021, I am working as a Machine Learning Engineer at Paradox Cat GmbH , developing prototypes for the automotive industry at BMW BetaLabs in Munich.

My background is in Space Science, in which I got my PhD in the Extraterrestrial Physics Group at Kiel University. During my PhD studies, I have been part of the scientific team of the RAD instrument on the Curiosity rover on Mars, and the Solar Orbiter Energetic Particle Detector . You can find links to my scientific publications and presentations on this website.
