Elias Gauthier
Cyberdefense engineering student · ENSIBS
I’m an engineering student in cyberdefense at ENSIBS (École Nationale Supérieure d’Ingénieurs de Bretagne-Sud, Université Bretagne Sud), in Vannes, France. After completing a Bachelor’s degree in Computer Science (BUT) at the University of Bordeaux, I’m pursuing this three-year programme to train in cybersecurity and cyberdefense, with the goal of joining the national defense and cybersecurity sector. Beyond my studies, I am interested in many areas of computer science, in particular digital forensics and cyber threat intelligence. I am paying close attention to the emergence of quantum computing and the related cryptographic challenges.
I also appreciate the world of open source. For example, I have contributed to the OCaml language library repository.
