I am working in the field of mathematical physics. My research focuses on the analysis of quantum many-body systems, in particular on the behaviour of dilute Bose gases.
My CV is available here
I am currently on parental leave until October 2024. From October I will be a professor for Analysis at FAU Erlangen-Nürnberg.
