Research

My research interests are in probability theory. I am particularly interested in the random growth models that belong to the KPZ universality class, geometric properties of the KPZ fixed point and the relevant processes, last passage percolation, exclusion processes, competitive erosion, stable random fields, percolation theory, Coulomb gas and random walks on graphs. Here is a link to my CV (updated periodically).
Following is a list of my publications and preprints.
