My research spans different aspects of data science, including machine learning, causal inference, graph mining, network science, and privacy. My research goal is to unify these aspects in a single framework that allows us to reason better with data and solve important societal problems. I am especially interested in algorithms for graphs and networks, with focus on:
I am motivated by compelling applications, and some of the areas that I study are personalization, social media, social networks, journalism, and e-commerce.
I am looking for highly motivated Ph.D. students to work with me. Send me an email with your interests and CV if you would like to explore topics together. You may also want to read this article on how to be a successful Ph.D. student.

I am an assistant professor in Computer Science at the University of Illinois at Chicago. Prior to joining UIC, I spent a few years in industry as a data scientist, working on recommender systems, personalization, incentivized sharing, and data science tools for journalists. I built and led the data science team at LivingSocial, and later was a principal data scientist at Vox Media. I also spent a year in government as an AAAS Science & Technology Policy Fellow at the National Science Foundation, contributing to national initiatives at the intersection of data science and public policy. Many of the research problems I am interested to solve are informed by my industry and public policy experience. I received my Ph.D. in Computer Science from the University of Maryland, College Park where my advisor was Dr. Lise Getoor.
