About me

profile.jpg I'm a postdoc at Inria Paris in the Prosecco Team. Previously I was a Ph.D. student under the supervision of Jean-Pierre Talpin and David Pichardie at INRIA Rennes. My research focuses on formal verification, via both dependently typed languages (mainly F*) and abstract interpretation techniques.

After a double bachelor in mathematics and computer science in France, I graduated with the master degree "Mathematical Foundation of Computer Science" at Radboud University in the Netherlands. You can find my resume here.

I like functional programming a lot: I'm a happy user of Haskell, PureScript and OCaml, occasional Coq and Idris user, and for a few years now, an F* enthusiast! I'm also a NixOS and an Emacs user.

Side projects

Here are some side projects of mine, more on my GitHub.

JS Star

A transpiler from F* code to JavaScript, written as an F* meta-program, that can run during F* typechecking phase.

F* libs

A set of F* libraries and meta programs.

Star Combinator

A tiny parser combinator library for F*.

F* Toy Static Analyser

A toy static analyser written in F*.

F* HTTP-Server

An HTTP server written as an F* meta-program, with a Elm like engine. I wrote a todo list application example in F*, that extracts as a web application.

Nix flake F*

A nix Flake for building F*, that makes it easy to deal with multiple different F* versions, with custom patches, local sources, etc.
