About Guilhem Niot

I am a PhD student at PQShield supervised by Thomas Prest, and 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 topicsrelated to privacy, applied cryptography and software security, ranging from analysing the securityof protocols, to writing efficient and secure software, or working on more theorical yet practicalcryptographic schemes.I also have a history of open-source contributions and maintenance and I value community-work and inclusiveness.
