About Me
Since 2020, I have been a professor at Telecom Paris, Institut Polytechnique de Paris, and the Head of the Cybersecurity-Cryptography team. I am also a collaborator with the CASCADE team at ENS.
I obtained a PhD in Computer Science at Ecole Normale Supérieure, under the supervision of David Pointcheval, then spent 15 months as a postdoctoral researcher at University College London and 9 months as a research engineer at France Telecom R&D. From 2007 to 2015, I was an assistant/associate professor at LAGA, University of Paris 8.
From 2015 to 2020, I was a professor at XLIM, University of Limoges and director of the Master 2 Maths CRYPTIS.
Research Interests
My research focuses on cryptography, particularly on "provable" security for cryptographic schemes including public-key encryption, digital signature, broadcast encryption, and traitor tracing. Recently, I have worked extensively on functional encryption, decentralized and privacy-preserving cryptosystems, and new paradigms for protecting Privacy under extreme adversarial settings, such as Anamorphic Cryptography.
My publications can be found on my research page.
Teaching Activities
My teaching activities include a range of courses from undergraduate to master's level, covering topics such as algebra, algorithms, advanced cryptography, computability and complexity. Additionally, I manage and coordinate master's programs, focusing on cryptography and mathematics applications, and supervise research initiation projects for students.
I have served as a member of the Steering Committee and the Studies Committee for the MPRI – Parisian Master of Research in Computer Science.
