Raphaël Monat

Research Scientist (he/him)

Inria & University of Lille

I am a research scientist in the SyCoMoRES team at Inria Lille. I hold a Ph.D in computer science, advised by Antoine Miné, during which I worked on the static analysis of Python (and Python+C) programs within the ERC MOPSA project. I have designed with Denis Merigoux a modern compiler for the French tax code, which is being transferred to the French tax administration.

The aim of my research is to improve the quality of software through the field of formal methods, and mainly automated program verification. I aspire to develop and apply methods to the most realistic systems possible. I have a particular interest in implementations of computational laws (taxes, benefits).

These days, I am exploring

  • ways to facilitate the adoption of static analysis tools,
  • developing formal methods tools for Catala, a domain-specific language for the implementation of legislative texts. This is a joint research project with Aymeric Fromherz.
  • static analysis of binary code following previous works of my team.

I am also one of the maintainers of the Mopsa static analyzer.

I am looking for motivated interns, PhD students, postdocs & collaborators. Applicants from all backgrounds, horizons, genders and ages are encouraged to apply. Informal inquiries are welcome, do feel free to send me an email!

Software

I strongly believe that academic prototypes accompanying research papers are important to show that a proposed technique works. I care about improving these prototypes to make them usable tools accessible to others, although it takes a lot of effort.

I am proud to be one of the core contributors of the following software:

Mopsa

Mopsa is a framework to write static analyses by abstract interpretation.

Mlang

Mlang is a new compiler for M, the domain specific language used by the French Tax Administration to compute the income tax. This is joint work with Denis Merigoux.

Notes on applying to CS faculty positions in France

These are a few notes regarding the application to CS faculty positions in France, based on my experience applying during the academic year 2021–2022. Please note: this is still valid in 2024 but may get outdated later on, this concerns early-career positions, there are also full professor or research director positions.
