Research Interests

My research field is the Probability Theory and its applications.

  • Statistical Mechanics (disordered systems, random polymers, interacting random walks, particle systems),
  • Random Trees.

    • My publications are available on arXiv or on HAL .
    I'm a member of the ANR LOCAL.
