About Me

I am a PhD student at PQShield supervised by Thomas Prest, and co-supervised by Pierre-Alain Fouque, Université de Rennes 1. I recently graduated from ENS Lyon, France and EPFL, Switzerland, and obtained a double Master of Computer Science. I am majoring in Cybersecurity and Cryptography and I’m very much interested into all topics related to privacy, applied cryptography and software security, ranging from analysing the security of protocols, to writing efficient and secure software, or working on more theorical yet practical cryptographic schemes.
