I am an Associate Professor and lead the SYmmetric and Lightweight cryptography Lab (SYLLAB) at Nanyang Technological University in Singapore since April 2012.
Previously, I was a PhD student at Orange Labs (former France Télécom R&D) and University of Versailles under the supervision of Henri Gilbert and Marc Girault. I also worked two years at Ingenico as Cryptography Expert, and at Nanyang Technological University as Research Fellow. My main research topic is the design and the cryptanalysis of hash functions, and more generally symmetric cryptography primitives.
