Sasha Bontemps

Since September 2026, am a postdoc at Universität Münster in the Operator algebra team under the supervision of David Kerr.

I recently defended my thesis at UMPA, ENS de Lyon, in the Geometry, Groups and Dynamics team. I have worked under the supervision of Damien Gaboriau on the space of subgroups of Generalized Baumslag-Solitar groups. You can find the manuscript of my thesis here and the slides of the defense here.

My research interests lie in geometric group theory and topological dynamics, including groups acting on trees. I am also interested in measured group theory.

You can find my CV here.
