I’m a Senior Scientist at the Berkeley Center for Human-Compatible AI (CHAI), working on recommender systems — the algorithms that select and rank content across social media, news apps, streaming music and video, and online shopping. I study how their operation affects well-being, polarization, and other things, and try to design recommenders that are better for people and society. For a decade I taught the double masters in computer science and journalism at Columbia Journalism School (lectures online). I led the development of Workbench, a visual programming system for data journalism, and builtĀ Overview, an open-source document set analysis system for investigative journalists. For a while I was an editor at the Associated Press, and I’ve also written for the New York Times, Foreign Policy, ProPublica, MIT Tech Review, and Wired. Before that, I did computer graphics R&D at Adobe Systems.
I live in Berkeley, California after previous stints in New York, Hong Kong, and Toronto. I like to make weird art with my friends.
