I obtained my PhD in theoretical physics at the university of Paris VI (France) in 1996, under the supervision of M. Mézard. The subject of the thesis was the out-of-equilibrium dynamics of spin glasses. I then spent two years at the Abdus Salam ICTP in Trieste, Italy, as a postdoctoral fellow. In 1998, I entered the National Council for Scientific Research (CNRS) of France with a permanent position as junior researcher. I spent 10 years at the Laboratoire de Physique Théorique at the University of Paris-Sud. I am currently CNRS senior researcher at the Centre de Physique Théorique in Marseille. I am also research scientist at the Complex Networks and Systems Group at the Institute for Scientific Interchange in Turin, Italy.
