Biography

I am a CNRS researcher working at GIPSA-lab (Grenoble, Image, Parole, Signal, Automatique) in the GAIA (Geometrie, Apprentissage, Information, Algorithmes) pole. I am co-head of the french working group on “Géométrie discrète et morphologie mathématique”. My research interests are digital geometry (géométrie discrète in french), computational geometry, and more recently combinatorial games and graphs. I am also involved in mathematics and computer science popularisation with the Maths à Modeler group and the online journal Interstices.

  • Digital geometry
  • Computational geometry
  • Combinatorial games and graphs
