Bio

Starting October 2025, I will be a Bonn Junior Fellow (temporary W2 Professor) at the University of Bonn
Currently, I am a postdoc at the Institut de Mathématiques de Jussieu - Paris Rive Gauche (IMJ-PRG) with mentorship by Bernhard Keller. I am supported by the MathInGreaterParis Fellowship Programme, which is a COFUND Marie Skłodowska-Curie Action.
Before that, I obtained my Ph.D. from the University of Hamburg in 2023 under the supervision of Tobias Dyckerhoff.

Research interests

Higher category theory, representation theory, noncommutative algebraic geometry. See Research for more details.
