Research

My current research interest is in statistical aspects of deep learning. Some topics include statistical learning, nonparametric regression, and adversarial examples. I’m also interested in applications to image and text data.

My PhD research was in network science, meaning problems inspired by social, biological, computer, and other types of networks. Network science draws on contributions from researchers in many fields, such as economics, computer science, physics, applied math, engineering, probability, and statistics. Specifically, I studied whether a network explains the propagation of a particular process and how to construct networks that explain processes from data.
