Who am I ? #

I am an INRIA senior research scientist (DR1) at INRIA Nancy (Loria).

My current responsibilities are:

  • (since 2016) Team leader of the CARAMBA research group.
  • (since 2021) Associate editor of Journal of Algebra
  • (since 2023) co-PI (with Gaëtan Leurent) of the Cryptanalyse project, under the umbrella of the PEPR Cybersécurité.
  • (since 2022) PI of the ANR Kleptomaniac project, focusing on key length estimates for classical public-key cryptographic primitives.

From 08/2021 to 08/2022, I was appointed as a visiting professor at University of California San Diego, Department of Computer Science and Engineering (my web page there might be still active), and I was also supported by a Fulbright Visiting Scholar grant, which was a joint financing effort of the French-American Fulbright commission and the Grand-Est Region.

I have a separate page with news.

Research interests #

  • The number field sieve and its cousins, notably for computing discrete logarithms over finite fields; relevant papers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24. See also some software: cado-nfs, as well as an example SageMath worksheet for NFS. Recent records also come with reproducibility data. See also my grad course at UCSD on this topic.

  • Sparse linear algebra over finite fields and the block Wiedemann algorithm; relevant papers: 1, 2, 3, 4, 5, 6. See also some software: cado-nfs.

  • Curve-based cryptography, and general computation related to small genus algebraic curves over finite fields; relevant papers: 1, 2, 3, 4, 5, 6, 7, 8. See also some software: cmh.

  • Computer arithmetic in general, in particular finite field and polynomial arithmetic; relevant papers: 1, 2, 3, 4, 5. See also some software: gf2x, mpfq, mploc.

I have a separate page with the complete list of my publications.
