Since October 2010, I am a CNRS research scientist in IRIF (ex LIAFA).
My main areas of research are enumerative combinatorics, random discrete structures, and algebraic combinatorics.
I am particularly
interested in the properties of maps (which are graphs embedded on
surfaces), and related combinatorial or algebraic objects (such as trees, graphs, Tamari intervals, or reflection groups).
with Louigi Addario-Berry, Omer Angel,Éric Fusy, Christina Goldschmidt.
an extended abstract of this work was presented at the conference
SODA 2018. Check the slides! (including a one-slide proof of the main result!) .
Papers (published or in press)
For most papers below I provide a link to an arxiv or to a local version. These versions are close but not necessarily the same as the published versions, including the numbering of equations and theorems. In particular check the journal versions if you need to cite anything.
A previous manuscript, entitled Tamari lattices and parking functions: proof of a conjecture of F. Bergeron and never submitted (since it was soon superseded by this one) is available there:
(previous-manuscript-arxiv).
It contains only the results on the dimension/enumeration, not the full representation, and it may be a more accessible, less technical, introduction to our method.

a related, less general, conference paper Are even maps on surfaces likely to be bipartite?
appeared in the proceedings of
MathInfo'08. It presents the results in the even degree case.
