Daphne Keller's work focuses on platform regulation and Internet users' rights. She has testified before legislatures, courts, and regulatory bodies around the world, and published both academically and in popular press on topics including platform content moderation practices, constitutional and human rights law, copyright, data protection, and national courts' global takedown orders. Her recent work focuses on legal protections for users’ free expression rights when state and private power intersect, particularly through platforms’ enforcement of Terms of Service or use of algorithmic ranking and recommendations. Until 2020, Daphne was the Director of Intermediary Liability at Stanford's Center for Internet and Society. She also served until 2015 as Associate General Counsel for Google, where she had primary responsibility for the company’s search products. Daphne has taught Internet law at Stanford, Berkeley, and Duke law schools.
