[1][2] He obtained his doctorate in information and security systems at the University of Lausanne in 2008 for a thesis on "Elaboration de tableaux de bord SSI dynamiques: une approche à base d'ontologies" (Developing dynamic ISS dashboards: an ontology-based approach) under supervision of Solange Ghernaouti-Hélie.

[1] In 2016, he assembled a multidisciplinary team composed of biometrics specialist Sébastien Marcel at Idiap Research Institute; cryptographer Serge Vaudenay, director of the EPFL's Security and Cryptography Laboratory, electronics engineer Pierre Roduit at HES SO Valais Wallis, and microtechnologist Eric Grenet at Swiss Centre for Electronics and Microtechnology.

This team jointly developed BioID and BioLocker, a patented biometric authentication technology based on multi-view vein scanningthat combines data security and respect for private sphere protection.

[4][5][6][7][8][9][10][11] He is the founder of GLOBAL ID SA,[12] a spin-off of EPFL that brings vein-based biometric authentication technology to the market.

[13] The biometric technology based on vein recognition is considered ethical because the key is hidden and therefore impossible to steal; the encryption is done end-to-end with a random code that changes constantly.
