# Professional information

Since January 2023, I am a PhD candidate at Université de Lyon (UJM-Saint-Étienne), in the SESAM team, under the supervison of Vincent Grosso and Pierre-Louis Cayrel. I work in embedded cryptography, with a focus on secure implementations of symmetric-key cryptography in the presence of physical attacks.

From 2021 to 2022, I was a cryptography engineer at CryptoExperts where I mainly worked on White-Box Cryptography. From 2019 to 2021, I completed my Master in Cryptology and Information Security (Cryptis program) at Université de Limoges.
