Background
Valentin worked at Inria on the formally-verified compiler CompCert during his undergraduate studies, where he implemented the first mechanically-verified alias analysis, and worked on checking the assembly and linking process for the PowerPC target architecture. He also authored the French translation of Learn You a Haskell (http://lyah.haskell.fr/). During his PhD at UC San Diego, he developed PeaCoq, a tool to make interactive theorem proving more user-friendly, and Chick, a tool to help in refactoring dependently-typed functional programs.
At Galois, Valentin has been working on automated translation of Cryptol code to Coq, and on a software provenance analysis tool based on the Nix package manager.
