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) coPI (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 publickey 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 FrenchAmerican
Fulbright commission and the GrandEst
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: cadonfs, 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: cadonfs.

Curvebased 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.
