I am a security researcher. I am working as a full-time researcher (Chargée de Recherche) for CNRS, at CRIStAL (Lille, France), in the Spirals group.
Previously, I worked as a CNRS researcher at IRISA (Rennes, France) in the EMSEC group.
Before that, I worked as a postdoctoral researcher in the Secure Systems group at the Graz University of Technology, Institute of Applied Information Processing and Communications, in Austria.
I obtained my PhD from Telecom ParisTech in October 2015 while working at Technicolor in Rennes, jointly with the S3 group of Eurecom in Sophia Antipolis.
Among other topics, I am interested in microarchitectural covert and side channels in commodity computers and servers, reverse-engineering processor parts, software-based fault attacks, and fingerprinting everything.
Career break: 6-month maternity leave from August 2023 to February 2024.
