I’m a data scientist, computational journalist, and researcher currently working as a research scholar at Columbia Journalism School and a fellow at the Institute for The Future. I lead the development of the Computational Journalism Workbench, a visual programming system for data journalism, and previously built Overview, an open-source document set analysis system for investigative journalists. I teach a course in computational journalism for the dual masters degree in computer science and journalism. I’ve written for the New York Times, Associated Press, Foreign Policy, ProPublica, and Wired.

I live in San Francisco, California, after previous stints in New York, Hong Kong, and Toronto.

You should contact me. Or, drop me a note @jonathanstray. I’m available for various types of work, such as training, data science, and journalism.
