Greetings 👋
I am a postdoctoral researcher at IRISA (Rennes, France) in the DiverSE team, working with Walter Rudametkin. My current research focuses on the intersection of Web privacy, tracking, and energy consumption.
I defended my PhD titled "Privacy-preserving communicaions for the IoT" in Sepember 2024 at INSA-Lyon / Inria as part of the Privatics Team, under the supervision of Mathieu Cunche and Vincent Roca. My doctoral research explored privacy in wireless IoT networks, with a particular focus on LoRaWAN, using both offensive and defensive techniques based on machine learning processes.
You can find a list of publications I've contributed to here.
Before my PhD, I graduated in 2021 from ENSIBS, a cyber-security-focused engineering school. As part of a work-study program during my studies, I worked as a pentester at Acceis.
