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.

Teaching
Here are notes I have developed for the introductory analysis classes I have taught at Chicago. I have not checked them for spelling/technical errors. Caveat emptor!
- 20300 Analysis I - Construction of real numbers, metric spaces, abstract vector spaces.
- 20400 Analysis II - Multivariable differentiation and integration on R.
- 20500 Analysis III - Multivariable integration and introductory differential forms.
