Sarah Brayne is an Associate Professor in the Department of Sociology. In her research, she uses quantitative and qualitative methods to understand whether and how data-intensive surveillance shapes individual trajectories and population-level disparities. Her first book, Predict and Surveil: Data, Discretion, and the Future of Policing (Oxford University Press), draws on ethnographic research within the Los Angeles Police Department to understand the social implications of law enforcement’s use of predictive analytics and new surveillance technologies. In earlier work, Professor Brayne developed a theory of “system avoidance,” using survey data to test the relationship between criminal legal contact and involvement in medical, financial, labor market, and educational institutions.
