Me at White Sands
Me at White Sands National Park

I am a PhD student in the MAX team at École Polytechnique under Joris van der Hoeven and Fredrik Johansson.

My research interests concern straight line programs, mainly focused on extreme performance of multiple-precision arithmetic. In particular, specialized code for different hardware is a big interest of mine.

I am a PhD and Postdoc representative at the LIX lab council. Some useful information for PhD students at LIX can be found in this section.

Publications

  1. PLMP – Point-Line Minimal Problems for Projective SfM
    With Kim Kiehn and Kathlén Kohn. Accepted as a highlighted article for ICCV, 2025. [arXiv], [Code]

  2. Fast basecases for arbitrary-size multiplication
    With Fredrik Johansson. ARITH 2025. [HAL]

  3. Eichler integrals and generalized second order Eisenstein series
    With Tobias Magnusson and Martin Raum. [arXiv]

Mathematical software

  1. JIL
    Together with Joris van der Hoeven, we are developing an SLP library Just-Inline.

  2. FLINT
    Co-maintaining FLINT together with Fredrik Johansson.

    FLINT is a high-performant library for polynomial arithmetic, exact linear algebra, rigorous ball arithmetic, special functions, …, used in software such as Sage, OSCAR, msolve and Macaulay2.

  3. ModularForms.jl
    A Julia-package for computing modular forms, developed with Tobias Magnusson and Martin Raum. Relies on the Julia packages AbstractAlgebra.jl, Nemo.jl and Hecke.jl.
