About me:


Research Interest:

My current research focuses on elliptic and parabolic integro-differential problems. In recent years this area has seen an increased number of publications with tools ranging from probability to analysis. My contributions belong to the analytical perspective but I am also very interested in learning new techniques. I wrote my PhD thesis on 2013 at the University of Texas in Austin under the supervision of Luis Caffarelli. I have worked on regularity estimates for viscosity solutions of fully nonlinear integro-differential parabolic equations, variational problems involving free boundaries and asymptotic shape theorems for queueing models.
