WE ARE RECRUITING: Postdoc/PhD candidates interested to work on cryptography/automated solvers/machine learning, please drop me an email!
I am Professor at Nanyang Technological University in Singapore and lead the SYmmetric cryptography and machine Learning Lab (SyLLab) since April 2012. I recently co-founded the start-up TT-logic.ai.
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 symmetric cryptography primitives, as well as applications of machine learning to security.
