About

I am a cryptographer working within CryptoExperts, a solution provider in the area of cryptography.

Before joining CryptoExperts in 2010, I have been a cryptography engineer at Oberthur Technologies (smart card manufacturer, now Idemia) and PhD student at University of Luxembourg (2006-2009) focusing on cryptographic implementations and side-channel attacks.

This webpage contains information about my scientific activities, publications, PhD thesis, and talks.
