Welcome
I am a CNRS researcher in the Love team at the LIPN. Here's a 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).
