Hey, I'm an editor at Nature Scientific Reports. You should go submit something!

News

I am looking for bright and motivated PhD students who are interested in network science, machine learning, crowdsourcing, and more!! Interested? More information

We're accepting applications for our Masters program in Complex Systems & Data Science! Interested? Apply now!

Research

Communities
Human mobility
Robust networks
Dynamics

I'm interested in the underlying rules and organizing principles of complex physical and social systems. My work combines mathematical models with large-scale data analysis to better understand these systems, with a particular emphasis on network science and human dynamics.
