Since 2006 my position is Maître de Conférences in UPMC (Paris 6
University). I joined the project-team INRIA/UPMC LIP6 POLSYS in 2008
(formely SALSA). My research activity focuses on computer algebra. More
precisely, I am interested in problems which are in the intersection
between computer security and polynomial systems solving.
In particular, one of my goals is to use intrinsic structures (e.g. symmetries) of polynomial systems in order to solve efficiently problems related to cryptology. A large part of the problems I try (and, fortunately sometimes succeeded) to solve are related to the cryptanalysis of number theory based cryptosystems as RSA and ECC.
From 2011 to 2016, I designed then took the co-responsibilities of a master program named Sécurité, Fiabilité et Performance du Numérique. I was the main responsible for the computer security part of this program.
From the beginning of 2017, I am détaché in ANSSI the French national authority in the area of cyberdefence and network and information security.
