My former training was in Math, afterwards I met Pr. Marcel-Paul Schützenberger
and started to be co-advised by him and Pr. Dominique Perrin for Ph.D and Habilitation.

Then I became interested in Combinatorics and Physics therefore, with friends and colleagues

• I founded the journal
  Combinatorics, Physics and their Interactions
  http://www.ihp.fr/en/annals
• I co-organized the cycle of conferences CAP
  Combinatorics and Arithmetic for Physics
  at IHES (Bures-sur-Yvette).
