I am a cryptographer working for Snap Inc.
Before that, I was a full professor at HEIG-VD, which is part of the University of Applied Sciences Western Switzerland (HES-SO) as well as a co-founder of strong.codes SA, a startup active in the domain of software protection. Besides teaching several topics of computer security to engineering students, I have provided high-quality consulting services and led several R&D projects in the areas of industrial cryptography and information security.
Even before that, I was working as a cryptographer for the Kudelski Group, world leader in the Pay-TV industry. Until March 2005, I have been a full-time teaching and research assistant at the Swiss Federal Institute of Technology in Lausanne (Switzerland), in the Security and Cryptography Laboratory led by Serge Vaudenay.
My main scientific interests are related to cryptography and cryptanalysis (design and cryptanalysis of symmetrical cryptographic primitives, broadcast encryption, industrial cryptography), software protection, software security and ethical hacking.
