I work in the field of Probability and Physics of disordered systems: more precisely, I am interested in polymer models.

Key words: Statistical physics, disordered systems, polymers, phase transition, critical phenomena, influence of disorder, random walks, renewal processes, first passage percolation…

I did my Ph.D. under the supervision of Fabio Toninelli, at École Normale Supérieure de Lyon (France), and I defended it in June 2012:
“Polymers in random environment: influence of correlated disorder on the localization phenomenon” (pdf).
