Brian C. Keegan

Brian C. Keegan is a computational social scientist and associate professor of information science at the University of Colorado Boulder. His research sits at the intersection of human-computer interaction, network science, and data science, exploring the structure and dynamics of large-scale online communication, collaboration, and the governance of online communities. He is a listed co-author of 'The Pushshift Reddit Dataset' (ICWSM 2020), the widely cited paper documenting the Pushshift platform that made comprehensive historical and real-time Reddit data available to researchers and supported a large volume of studies of subreddits, users, and comment behaviour. His broader scholarship on peer production and online communities frequently draws on platforms such as Wikipedia and Reddit as sites for studying how people coordinate, govern themselves, and respond to disruptive events at scale.
