I am a CNRS researcher at IRMAR (Rennes, France).

- 2018-2021: PhD under the supervision of Patrick Gérard at the Laboratoire de Mathématiques d'Orsay (LMO).

- 2021-2022: Institute postdoc at ICERM (Brown University)

- 2022-2023: postdoc at the University of Basel with Enno Lenzmann

I am interested in the long time behavior of solutions to dispersive nonlinear PDEs. I mainly focus on PDEs with wery weak dispersion (for instance, the Schrödinger equation on the Heisenberg group) and on integrable PDEs (for instance, the Benjamin-Ono equation on the torus). Here is a lay summary of the zero-disperion limit problem for the Benjamin-Ono equation on the torus.

Here is my PhD manuscript entitled "Long-time behavior of solutions to nonlinear PDEs: orbital stability of traveling waves, dispersion, integrability, damping".
