Deb Roy
Also known as Deb Kumar Roy
Deb Roy is a professor of media arts and sciences at MIT, where he directs the Center for Constructive Communication and leads research on human-AI systems for dialogue. His Human Speechome Project recorded nearly all of his infant son's waking hours from 2006 to 2009, and his 2011 TED talk followed how his son learned language. Roy co-founded Bluefin Labs in 2008, a social TV analytics company that Twitter acquired in 2013. In 2018 his study of false news, written with Soroush Vosoughi and Sinan Aral, became a Science cover story. Across 2025 and 2026 he co-authored a paper on conversation networks and published an Atlantic essay on large language models.
