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 algorithmic number theory 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 algorithmic number theory.
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.
