My research fields are: Cryptography, Applied Mathematics, Computer Algebra, and Computer Science.
In particular, I work on Algebraic Attacks against Post-Quantum cryptosystems.
In order to study the security of these cryptosystems, I evaluate the complexity of computing Gröbner bases of systems of multivariate polynomials over finine fields.

I am one of the authors of the current best attacks against the Rank Decoding and MinRank problems; these two problems are at the core of rank and multivariate-based cryptography.

I am part of the RQC team; Rank Quasi-Cyclic (RQC) is a rank-based cryptosystem which made it to the 2nd Round of the NIST Post-Quantum Standardization Process.

I am one of the scientists who introduced the SquareSpace problem in 2022. This problem relies on the factorization of vector spaces, and we used it to design new post-quantum signature and encryption schemes.
