I am an associate professor at the University of Picardie Jules Verne and a member of the GOC group. Formerly I was a post-doc in the INRIA LFANT group and a visiting researcher with Microsoft Research in Redmond. I am a former PhD student of Antoine Joux.

I work in the area of algorithmic number theory and its applications to cryptography. My current research is mainly focused on:
Current projects


  • Publications

  • Selected talks

  • Software

  • ScalarMult is a C++ implementation of scalar multiplication on several families of elliptic curves and genus 2 Jacobians.

  • CMGenus3 is written mainly in Sage. It implements an algorithm for constructing genus 3 hyperelliptic Jacobians with CM. See also our paper "Constructing genus 3 Jacobians with CM".
