I work as maître de conférence at Université Paris-Sud, in the Numerical Analysis and Partial Differential Equations team.

I was a PhD student at the University of Cergy-Pontoise. My advisor was Mathieu Lewin. I defended my thesis on december, 12th 2013. 

From october, 2013 to march, 2014, I was in Caltech for a research stay, in collaboration with Rupert Frank.

You can download my thesis here

You can download my Curriculum Vitae here.

Research interests:

- Nonlinear Analysis;
- Variational Methods;
- Dispersive Partial Differential Equations, Strichartz estimates;
- Spectral Theory;
- Mathematical Physics, Relativistic Quantum Mechanics, Electron-Positron Pair Production.
- Harmonic Analysis.
