Research Work
My research lies in the field of Probability Theory and its applications to models of statistical physics (random media, random polymers, KardarParisiZhang universality, scaling limits of disordered systems, Stochastic PDEs). I am also interested in the relations to random matrices, PDEs, representation theory and combinatorics.
