Professor Deb Roy

Director & Principal Investigator

Deb Roy is professor of Media Arts and Sciences at MIT where he directs the MIT Center for Constructive Communication (CCC). He leads research in designing human-AI systems that foster dialogue, listening, and deliberation in ways that build civic muscle. Roy is also co-founder and unpaid CEO of Cortico, a closely affiliated nonprofit collaborator of CCC that develops, operates and supports a conversation platform designed to surface underheard voices and perspectives and create scalable dialogue networks.

Previously, Roy was a visiting professor at Harvard Law School (2021-22), and served as executive director of the MIT Media Lab (2019-2021), where CCC is based. Earlier, while on leave from MIT, Roy co-founded and was CEO of Bluefin Labs, a media analytics company that analyzed the interactions between television and social media at scale. Bluefin was acquired by Twitter in 2013, Twitter’s largest acquisition to date. From 2013-2017 Roy served as Twitter’s chief media scientist.

Currently Roy serves on the board of the Knight First Amendment Institute and the FRONTLINE advisory council. He previously served on the Knight Commission on Trust, Media, and Democracy and the Aspen Institute’s Commission on Information Disorder

Roy is the author of over 185 academic papers including a study of the spread of false news that was the cover story of Science magazine in 2018 and cited as one of the most influential academic publications of the year. His 2023 essay in The Atlantic describes his journey from studying social media to creating dialogue networks, and his 2024 Atlantic essay explores ways to tackle truth decay. Roy’s widely viewed TED talk Birth of a Word presents his pioneering research on his son’s language development that led to new ideas in media analytics.
