Research

Broadly, my research is 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.

My current research focuses on statistical aspects of network science. In particular, I study whether a network explains the propagation of a particular process and how to construct networks that explain processes from data. I also enjoy aspects of network science related to machine learning.
