I am Associate Professor at Sorbonne University, where I work in the PolSys team within the computer science lab (LIP6). My main interest is on post-quantum cryptography, a new generation of cryptography that is secure against classical and quantum adversaries.

My research specialities include the design of new post-quantum post-quantum primitives and the security analysis of various cryptosystems with algebraic techniques, also known as algebraic cryptanalysis, using tools from symbolic computation such as Gröbner bases.

Post-quantum cryptography startup

I am the co-founder of Cryptonext Security, a spin-off from Sorbonne University, CNRS and INRIA. Created in 2019, together with Jean-Charles Faugère, CryptoNext Security is the french pioneer and the european leader of post-quantum cryptography.
