I am an Assistant Professor (Maître de conférences) at the Institute of Technology (IUT) of Saint-Denis, and a member of the Laboratoire d'Informatique de Paris Nord (LIPN) in the team Combinatoire, ALgorithmique et INteractions (CALIN). I arrived there in 2013.
I worked at the Institut de Recherche en Informatique Fondamentale (IRIF) in 2019-2020 when I obtained a year at CNRS (accueil en délégation).

Before that, I was a postdoctoral fellow at Perimeter Institute for Theoretical Physics, Waterloo, Ontario, Canada, from 2010 to 2013, supported by a MRI grant from the Government of Ontario.

My Research interests

Combinatorial problems related to high-energy or statistical physics, in particular combinatorial approaches to quantum gravity
Combinatorial physics is one of the two axes of the CALIN team in LIPN!
  • Combinatorics of graphs, trees, maps and higher dimensional triangulations
  • Integrable hierarchies in combinatorics and applications
  • Random matrix models and random tensor models
  • Topological recursion
  • Combinatorics of low-dimensional topology and geometry
  • Quantum invariants of manifolds
  • Spin networks and spin foam models


All preprints available here on the arxiv! You can find my Ph.D. manuscript, in French, here.

I have had 28 co-authors.
