From September 2015 to August 2018, I was a PhD student in algebraic topology at the University of Copenhagen. My PhD advisor is Jesper Grodal. Starting in October 2018, I will be a postdoc at the University of Bonn.

See my CV (last updated: September 2018).

Research Interests

My main mathematical interests lie in unstable and stable equivariant homotopy theory, their relationship, and the interplay with additional algebraic structure such as ring or module structures. Moreover, I am interested in the theory of finite groups and compact Lie groups, their representation theory, tensor-triangulated geometry, and equivariant structures in commutative algebra (e.g. Mackey and Tambara functors). I also have an outside interest in the G-infinity categories of Barwick et al., chromatic and motivic homotopy theory.
