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