About

I hold a PhD in computer science from both UQÀM (Canada) and Univ Rennes (France), supervised by Sébastien Gambs and Tristan Allard. My research interests cover various aspects of privacy, fairness and related societal issues. I have a focus on ethical issues of using artificial intelligence for high-stakes decision-making.

At present (2026), I am working with Afnic on the social use of .fr domains at the content level.

I have a master in computer science from ENS Rennes. In 2018, I did an internship at Inria Grenoble, supervised by Claude Castelluccia and Daniel Le Métayer, working on privacy risk analysis of national identity schemes. I did an internship at IT University of Copenhagen with Philippe Bonnet researching edge computing storage. I did two internships at IRISA in 2016 and 2017 studying privacy-preserving crowdsourcing with Tristan Allard and David Gross-Amblard.
