About

CNRS research scientist in the Algorithms and Complexity team of IRIF, Université Paris Cité. My research interests include zero-knowledge proofs, multiparty computation, and the theoretical foundations of cryptography. For more information about my work, or opportunities for internships / PhDs / postdocs, see my website: http://geoffroycouteau.fr/.
