Winter 2018-2019 I taught a course on nonpositively curved manifolds.

December 2019 I taught a minicourse on Lens spaces, examples of group actions and (a drop of) surgery.

December 2021 I taught a minicourse on L^2-invariants, homology growth and embedding theory. 

Summer 2024 I am teaching a course on the topology of 2-complexes.
