I have a full research position at CNRS (in French “chargé de recherche”). I belong to the research team AMACC of GREYC lab (UMR CNRS 6072).


  • Lattice reduction algorithms
  • Analysis of algorithms based on data structures (tries and binary search trees) with non uniform probabilities with tools like generating functions, Mellin transform and functional analysis.
  • Study of patterns occurences in texts with applications to biology.
  • Optimal prefix codes for infinite alphabets.


My publication list contains some papers that are available in postscript and/or pdf form.


GdR Informatique Mathématique

I am involved in the GdR Im (Groupe de recherche) Informatique Mathématique (a CNRS structure). Currently I manage the mailing list.

I belong to several working groups: ALEA, SeqBIM, Codage et Cryptographie and SDA2 : Systèmes Dynamiques, Automates et Algorithmes.
