Research:
You can find below a short statement about my research.
My full CV (in pdf and in english) is [here].
You can also visit my [Web page in french].  

Domain: Mathematical physics / Probability 

Interests:
• Random walks and spins models on random graphs and networks.
• Asymptotical behavior of first passage times.
• Exit and hitting times of local equilibria.
• Recursive scale-free graphs and trees.
• Cut-off and escape behaviors for random walks.
• Link between cut-off phenomenon and exit from metastability.
