Pierre Briaud

I am a 3rd year PhD student in the Inria project-team COSMIQ, where I am advised by Jean-Pierre Tillich. I am expected to graduate by December 2023.

My main research interest is algebraic cryptanalysis. During my PhD, I spent the summer of 2023 working with Ray Perlner at the National Institute of Standards and Technology (NIST).
