Welcome to my personal webpage


Since September 2016, I am maître de conférence in Dijon.

Séminaire GSD: Avec Frédéric Déglise je suis le responsable du séminaire de Géométrie et Systèmes Dynamiques.

Groupe de travail: J'organise aussi un groupe de travail plus ou moins régulier « Dynamique des actions de groupes».

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

In preparation:
