My research interests include all aspects of cryptology, and more generally, of computer security. I however focus particularly on the design and analysis of cryptographic primitives such as hash functions, stream/block ciphers, lightweight cryptography as in RFIDs, multivariate schemes, aspects of privacy, and content &s; software protection.

My Ph.D. thesis (UVSQ, 2005) was supervised by Henri Gilbert and Jacques Patarin.
Before that, I completed my master thesis under the direction of Marc Joye.
More on my background here.

I organised Eurocrypt 2010 together with Matt Robshaw, was on the board of the IACR during 2009 and 2010, and co-designed the ECHO hash function for the SHA-3 competition.
