I am a professor at HEIG-VD, which is part of the University of Applied Sciences Western Switzerland (HES-SO). Besides teaching several topics of computer security to engineering students, I provide high-quality consulting services and lead R&D projects in the area of industrial cryptography and information security.
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, especially to the design and cryptanalysis of symmetrical cryptographic primitives; for instance, I am a co-designer of the award-winning IDEA NXT block cipher (also known as FOX).
