I am an assistant professor at the University of Connecticut. My research interests include metric geometry, functional analysis, geometric measure theory, and harmonic analysis. Before Connecticut, I was a L.E. Dickson Instructor at the University of Chicago, and I received my Ph.D. from the Courant Institute at NYU under the supervision of Professor Assaf Naor.
