Research

I study Geometric Group Theory, more precisely the geometry of CAT(0) cube complexes and the outer space of right-angled Artin groups, supervised by Vincent Guirardel. I am also interested in Baumslag-Solitar groups and general graphs of free groups.

Untwisted McCool groups for right-angled Artin groups have Type VF, in preparation

Introductory video (in french) to the mathematics of origami:

The following images come from 3D models and can be rotated to see them from every angle.

Dupin's cyclide, a cubic surface obtained by inverting a torus at one of its points. It contains 4 real lines and each has complement fibered by circles. Flipping the object over corresponds to the automorphism exchanging the two coordinates of the torus.
