Welcome
I am a CNRS researcher in the Love team at the LIPN.
Previously, I was post-doc with Assia Mahboubi, at Inria Gallinette. Before that, I did my PhD thesis at the IRIF, under the direction of Thomas Ehrhard.
Here's a short CV.
My research is motivated by the gap between the theory programming languages and the applications of programming languages to continuous mathematics. It lies at the interface of Logic, Formal Proofs and Functional Analysis. I am a happy participant to the Math-Comp Analysis project. I am a member of the ANR ∂IFFERENCE (starting in 2020) and Nuscap (starting in 2021).

News:
- I will give an invited talk at the AIPLANS workshop, colocated with NeurIPS 2021, on Dec. 14th.
- Jean-Simon Pacaud Lemay came to the LIPN lab for a 10 day research visit (october 2021).
- Valentin Maestracci started a 6 month internship on *-autonomous differential categories (October 2021).
- Simon Mirwasser ended his M2 internship on an indexed Differential Logic, co-supervised by Flavien Breuvart and I (August 2021).
Students and Interships
I am always happy to work with students. If you have a taste for logic and love to open analysis books, please do not hesitate to contact me !
I'm also happy to supervise formalizations projets in Coq.
