Bio

I am a Professor (Bonn Junior Fellow, temporary W2) in the Mathematical Institute at the University of Bonn.
Previously, I was a postdoc at the Institut de Mathématiques de Jussieu - Paris Rive Gauche (IMJ-PRG) with mentorship by Bernhard Keller.
Before that, I obtained my Ph.D. from the University of Hamburg under the supervision of Tobias Dyckerhoff.

Research interests

Higher category theory, representation theory, noncommutative algebraic geometry.

Upcoming

Masterclass on Interactions between homotopy theory and representation theory in Copenhagen. 10-14 November 2025.
I will give a mini-course with the title "A gentle introduction to sheaves of stable ∞-categories". Link.
