Since September 2016, I am maître de conférence in Dijon.
In the academic year 2018/19 I will be working at Lille (délégation at INRIA and Laboratoire Paul Painlévé).

At the present moment I am studying groups of circle diffeomorphisms that could be considered as geometrically finite
inside \(\mathrm{Diff}(\mathbf{S}^1)\).
