My research interests fall into the area of geometric group theory. That is, I study groups as coarse geometric objects. I am particularly interested in lattices on buildings, such as arithmetic groups and Kac-Moody groups. Other classes of groups I am interested in are relatives of Thompson's groups F, T and V and Artin groups. Many of these groups act on non-positively curved spaces, although often not cocompactly.

I'm a postdoc at in Bielefeld where I obtained my habilitation in 2017. Before I was a postdoc in Münster. I did my PhD in Darmstadt.

In 2019 I will work at École Polytechnique as a Feodor-Lynen Fellow of the Humboldt Foundation. When I return I will be member of the DFG Heisenberg Programme.

My student Eduard Schesler works on Sigma-invariants of S-arithmetic subgroups of Borel groups.

I am funded through the DFG via the project WI 4079/2 and am member of the SPP 2026.

I was one of the organizers of the conferences Topological and Homological Methods in Group Theory and Topological and Homological Methods in Group Theory 2018.
