Short bio

I am Professor at EPITA, LRE in the Security and Systems group since October 2024 and associate member of LIP6. Before joining EPITA, I was an associate professor at Sorbonne University, LIP6 in the PolSys team during 17 years. In 2005, I received a PhD thesis in Computer Science from Marne-la-Vallée University and defended my habilitation thesis in 2016 at Sorbonne University (formerly Paris VI). From 2018 to 2022, I was on leave from my academic position as a co-founder of CryptoNext Security, a post-quantum cryptography start-up. My expertise is in the design, analysis, and deployment of post-quantum cryptography.
