Short Biography and Research Interests

I am an associate professor ("maître de conférences") since September 2014 at Univ Rennes, CNRS, Irisa. Before that, I was a postdoctoral researcher at the Inria Zenith team in Montpellier. I conducted my Ph.D. thesis in Computer Science in the Inria SMIS team and received it from the University of Versailles in December 2011.

The volume, variety, and velocity of digital personal data are increasing at a fast pace. Enabling both daily uses and large-scale analysis of personal data while preserving individuals' privacy is a key challenge in building a knowledge society. My research interests lie within this wide field. I am particularly interested in the combination of differential privacy with cryptography (privacy-preserving data querying, privacy-preserving crowdsourcing, privacy-preserving data mining). And recently I got diverted by the study of browser fingerprints for web authentication.
