Jérémie Unterberger

 I am currently assistant professor at the maths institute  IECL (Institut Elie Cartan de Lorraine), in the Probability and Statistics team.

My research interests include constructive field theory (rigorous renormalization techniques), mathematical physics, statistical physics, stochastic calculus, and random matrix theory.
