The following keywords recap my main research interests:
- formal methods: formal proof assistants (Coq, SSReflect, PVS), formalization of mathematics, type theory, proof theory, classical and intuitionnistic logics, formal specifications, formal verification, certificates;
- numerical methods: computer arithmetic, floating-point arithmetic, correct rounding, certified polynomial approximation, interval arithmetic, global optimization, computer algebra;
- game theory: formal proof for game theory: formalization of Boolean games, determinacy, games in normal form...
- software engineering : CI/CD, automating tests, V&V or continuous deployment...
Current Research Activities
My research activities focus on the applications of interactive formal proof, in particular for the formal verification of results in computer arithmetic and game theory.
I am also interested in designing methods to increase proof automation within formal proof assistants, as well as automating tests in general and specifically around the tooling of projects in the OCaml and Coq community.
Since the 1st September 2014, I am Associate Professor (Maître de Conférences) at the Université Toulouse III – Paul Sabatier and I do my research in the ACADIE team of the IRIT research lab.
Previously, I was a postdoc in the VALS/Toccata team of LRI (UMR 8623 CNRS & Université Paris-Sud) at Inria Saclay - Île-de-France and was involved in the VERASCO project of the French ANR.
Before that, I was a postdoc in the Marelle project-team at Inria Sophia Antipolis, and was involved in the TaMaDi project of the French ANR.
I defended my PhD thesis on the 26th September 2012 in ENS de Lyon, where I worked in the AriC project-team (formerly known as Arénaire) of the LIP research laboratory, under the joint supervision of Jean-Michel Muller and Micaela Mayero.
My PhD manuscript and my PhD defense slides are available online.

Internship proposals (2022-2023)
If you are strongly interested in one of the research topics that I mention, but no internship proposal about it appears at the time, feel free to contact me and send me a CV+cover-letter, to discuss a possible internship supervised by me within the ACADIE team.
||In particular, I belong to the steering committee of the Master DL for which I do most of my teaching activities.
