A Multilanguage Static Analysis of Python/C Programs with Mopsa

Mopsa is a conservative static analysis platform, independent of language and abstraction choices. Developers are free to add arbitrary abstractions (numeric, pointer, memory, etc.) and syntax iterators for new languages. Mopsa encourages the development of independent abstractions which can cooperate or be combined to improve precision.

Formal methods for realistic systems: a study of two cases

The goal of my research is to improve the quality of software. I use for that the field of formal methods, in order to define precisely the behavior of programs. This allows to reason rigorously about these behaviors (to detect dangerous states for example).

Static Type and Value Analysis by Abstract Interpretation of Python Programs with Native C Libraries

We aim at designing both theoretically and experimentally methods for the automatic detection of potential bugs in software – or the proof of the absence thereof. This detection is done statically by analyzing programs' source code without running them.

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:

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.

Mopsa

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

Internships

Master Internship #3: Static Analysis by Abstract Interpretation: Collecting Types of Python Programs

From March to August 2018, I worked under the supervision of Antoine Miné at the LIP6 laboratory, in Paris, France. I designed a static analysis by abstract interpretation that detects potential type errors in Python programs.

Master Internship #2: Formal Verification of a Static Analyzer

From February to June 2017, I worked under the supervision of Eva Darulova at the Max Planck Institute for Software Systems (MPI-SWS), in Saarbrücken, Germany. I worked on a static analyser of floating-point programs called Daisy.

Master Internship #1: Black-box Variational Inference in Probabilistic Programs

From May to July 2016, I worked with Hongseok Yang at the University of Oxford, United Kingdom, on “Variational Inference in Probabilistic Programs”. During this internship, we expressed probabilistic programming languages into probabilistic transition systems.

Bachelor Internship: BATMAN, a BAsic Thread-Modular ANalyzer

From June to July 2015, I worked under the supervision of Antoine Miné at the École Normale Supérieure, France, on static analysis by abstract interpretation of concurrent programs. I learned how to use the Abstract Interpretation framework to develop, implement and test new methods to analyze concurrent programs more precisely.
