Renée DiResta is an Associate Research Professor at the McCourt School of Public Policy at Georgetown. Previously, she was technical research manager at Stanford Internet Observatory, a cross-disciplinary program of research, teaching and policy engagement for the study of adversarial abuse in current information technologies. She studies the many ways that people attempt to manipulate, harass, or target others online. Much of her work focuses on rumors and propaganda, and in understanding how narratives spread across social and media networks. DiResta researches novel and rapidly-developing problems, then communicate findings both to the public and to those best positioned to mitigate them. She advised Congress, the State Department, and myriad civil society and business organizations on the mechanics of online manipulation in its many forms: computational propaganda, conspiracy theories, terrorist activity, and state-sponsored information warfare.
