About me

I am a PostDoc (Akademischer Rat auf Zeit) at the University of Bonn and a member of the Topology group. Between 2016-2019 I was a PostDoc at the University of Copenhagen, and before that I obtained my PhD at the University of Bonn under the supervision of Stefan Schwede.

Research interests

I work in algebraic topology, in particular (equivariant) stable homotopy theory, chromatic homotopy theory, tensor-triangular geometry and geometric group theory.
