Short Bio
I received a PhD degree in Applied
Sciences (Cryptography) from the Université Catholique de
Louvain (UCL) in 1997 and an Habilitation (HDR) degree in Computer
Science from the Université de Toulouse II in 2003. In
1998 and 1999, I was a post-doctoral fellow of the National Science
Council, Republic of China. From 1999 to 2006, I was with the Card
Security Group, Gemplus (now Gemalto), France. Since August 2006, I
have been with the Security & Content Protection Labs,
Technicolor (formerly
Thomson), France. I am author and co-author of 100+ scientific
papers and hold several patents. I served in numerous program
committees and was program chair for CT-RSA 2003,
CHES 2004, ACM-DRM 2008, FDTC 2010,
ACM-DRM 2010, Pairing 2010, and
InfoSecHiComNet 2011. I am a member of the IACR
and co-founder of the UCL Crypto Group.
