I am an assistant professor at EPITA since September 2025.
From January 2021 to August 2025, I have been an engineer at Thales Group.
From October 2019 to December 2020, I have been a postdoctoral researcher at LIX (Laboratoire d'Informatique de l'Ecole Polytechnique) and from September 2018 to September 2019 in the Symbolic Computation group at the University of Waterloo (Ontario).
From September 2015 to September 2018, I have been a Ph.D. student at Université de Lorraine, and a member in the LORIA's project-team CARAMBA, under the supervision of Pierrick Gaudry and Pierre-Jean Spaenlehauer. Meanwhile, I have also been a teaching assistant at Mines Nancy.
I defended my thesis on September 7, 2018. Here is a link to the manuscript and to the slides of the defense (both in English). Errata: in the RM case, the exponent in the complexity should be 9 instead of 8 (and the conjectured bound is then 7 instead of 6). This has been corrected in a more recent article published in the Journal of Complexity.
Currently, my work is divided into two main topics: applied (post)quantum cryptography with a view towards space applications, as well as the cryptanalysis (both classical and quantum) of multivariate signature schemes. More generally, my work aims at solving algorithmic problems for a variety of applications in Cryptology and Coding theory.
To do so, the following areas of Mathematics and Computer Science are of particular interests to me:
