Dr. J. Nathan Matias

I study digital governance and behavior change in groups and networks shaped by algorithms. I collaborate with the public in citizen behavioral science, working for a world where digital power is guided by evidence and accountable to the public.

I am a Guatemalan-American assistant professor at the Cornell University Departments of Communication and Information Science, where I lead the Citizens & Technology Lab (full bio here). My research contributes to scholarship in social pscychology and computer science.

I am currently a 2022-23 Lenore Annenberg and Wallis Annenberg Fellow in Communication and Siegel Research Fellow at the Center for Advanced Study in the Behavioral Sciences, Stanford University. In the summer of 2022-23, I am also an visiting associate research scholar at the Knight First Amendment Institute at Columbia University.


From May 31 to June 6th 2023, the media artist and writer Ivan Sigal and I are bicycling 500+ miles from Bakersfield to Sacramento and then the ocean, following the route of the 1966 farmworkers movement and writing a series of stories about the ride. You can learn more about the project here: Cycling in the footsteps of the California Farm Workers March.

Guide for Journalists & Event Organizers

As someone who regularly gives keynotes, appears on panels, and commits acts of journalism, I do what I can to support high quality conversation on tech and society: as a speaker, as a source, and by helping you find experts. I also collaborate with journalists on data journalism projects related to tech companies, their policies, and online behavior. To invite me to give a talk, see my page about talks and speaking.

Reach out if I can help; over the last few years I have supported journalists on background, with suggested sources, statistics feedback, and served as a named source for journalists from the New York Times, Washington Post, Wall Street Journal, ProPublica, The Markup, NPR All Things Considered, WIRED, The Atlantic, The Guardian, Boston Globe, Canadian Broadcasting Company, FastCompany, Fortune, Chronicle of Higher Education, Nieman Journalism Review, and the Columbia Journalism Review, to name a few.
