Cross-National Collaboration in Open-Source Software
When one lifts away the predominant US-based software projects in Github, we see the lasting traces of deep-seated culture, geopolitics, and colonial history in cross-national collaboration among software developers on Github.
This fun collaboration grew out of a network visualization assignment that my students completed in my network analysis course (co-instructed with Bogdan Vasilescu).
Opinion Polarization in Social Media
Modern social media envisioned a connected world with openness, transparency, and fluidity of information exchange. Why, then, have political polarization and social division exacerbated in social media?
Origins of Network Wormholes
People enjoy the company of those who are similar to themselves. Then why do rare bridging ties between socially distant and dissimilar people exist in population-scale social networks?
Higher-Order Interactions as Social Ritual
Social networks are powerful analytic representations of social systems, built up from the collection of social ties between individuals.

Do group interactions with ritualistic character occur in online settings? How can we identify and study them using alternative analytic representions?
Informal Collaboration and the Production of Disruptive Knowledge
Large-scale collaborations have become prevalent in science, but why does disruptive knowledge tend to originate from smaller teams?
