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). I am available for all kind of discussions, dialogs and co-creations around subjects standing at the triple point Mathematics - Physics - Computer Science. ©
