About me:

I am a postdoctoral researcher in the Department of Mathematics of the University of Luxembourg, in the group of Hugo Parlier. My research is at the interface of low-dimensional topology and geometric group theory. More specifically, my work has been related to the large scale geometry of mapping class groups of surfaces and various graphs and complexes on which they act, such as the curve complex.

Previously, I was a postdoctoral researcher at the Institut des Hautes Études Scientifiques. Before that, I spent six months at the Fields Institute for the Thematic Program on Teichmüller Theory, and before that, I was a PhD student at the University of Warwick, under the supervision of Brian Bowditch.
