Hi, I’m Léo

I’m a doctoral researcher at the chair Cyber CNI supported by IMT Atlantique. Before that, I received an engineering degree in information security from ENSIBS and worked at Orange Cyberdefense as a part-time employee for three years.

Research Interests

My research focuses on the collaboration in security systems, and how to share data without compromising security. I rely on topics like federated machine learning, intrusion detection, and collaborative knowledge sharing. With the chair and its test bed, I work on tools and strategies for collaborative attack detection, characterization, and mitigation.
