I am a Ph.D. student at the University of Bonn. My advisors are Catharina Stroppel and Tobias Dyckerhoff. I am currently (01.10.2019-30.03.2020) a guest of the Max Planck Institute for Mathematics.

I am interested in higher category theory, homotopical and homological algebra and their applications to representation theory, categorification and topological field theories.
