I received my Phd degree in Computer
Science from the University Paris-Orsay (Paris-XI) for my work
on dependable systems. I spent a post-doctoral year at Cornell
University (NY - USA) and worked with Sam Toueg on unreliable
failure detectors. I spent a great year there ! I am a CNRS researcher at IRISA-UMR6074
lab. My current research group is the INRIA
CIDRE research team. I investigate
dependability and security issues in large scale and dynamic systems.
For the last few years, I have been working on data stream
algorithms, reputation mechanisms, dependability issues in peer-to-peer systems, and more recently on blockchain technologies.
