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

Research
At the present moment I am studying groups of circle diffeomorphisms that could be considered as lattices
inside \(\mathrm{Diff}(\mathbf{S}^1)\) (even if the notion of lattice is unclear).
In preparation:

Sharp differentiable rigidity of Fuchsian groups,
in preparation (joint work with
Bertrand Deroin and
Victor Kleptsyn).

Markov partitions and locally discrete groups of realanalytic circle
diffeomorphisms,
in preparation (joint work with
Sébastien Alvarez, Pablo Barrientos, Dmitry Filimonov,
Victor Kleptsyn,
Dominique Malicet, and
Carlos Meniño).
Publications and preprints:

Hyperbolicity as obstruction to smoothability for onedimensional actions,

Christian Bonatti and Yash Lodha)

Groups with infinitely many ends acting analytically on the circle,
