Greetings 👋
I'm a third-year PhD student at INSA-Lyon / Inria, part of the Privatics Team, supervised by Mathieu Cunche and Vincent Roca. My research focuses on privacy in wireless IoT networks, specifically LoRaWAN. Additionally, I have interests in other areas such as privacy and security on the web.
You can find a list of publications I've contributed to here.
Prior to this, I graduated in 2021 from ENSIBS, a cyber-security-focused engineering school. During my studies, I participated in a work-study program as a pentester at Acceis.
