My current research interest is in statistical aspects of machine learning. Some concrete problems include imbalanced classification, adversarial examples, and other variations on statistical learning. I also work on applied problems in statistical climate prediction.

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.
