I was a Ph.D. student at the University of Bonn. My advisors were Catharina Stroppel and Tobias Dyckerhoff.

Since 1st of April 2020 I work as a postdoctoral researcher at the Technical University of Munich.

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