BA, Harvard; PhD in Psychology, Stanford. National leader in the science of racial bias by pioneering scientific experiments that exposed how our minds learn to associate Blackness and crime implicitly—often with deadly consequences. Work also exposed the disturbingly robust finding that both college students and officers overestimate the age of Black children, a cognitive error that predicts higher levels of police force against those children. This research led to co-founding of the Center for Policing Equity (CPE), a university research centre now supported by the 501c3 Policing Equity organization. Created at UCLA, the centre has grown to be the world’s largest research and action think tank on race and policing. CPE also boasts the world’s largest collection of police behavioural data in the National Science Foundation-funded National Justice Database, which they have turned into a tool to reduce burdensome and inequitable policing through scientific analyses. Has won two American Psychological Association early career awards, the Association for Psychological Science Rising Star award, and the National Organization of Black Law Enforcement Executive’s Lloyd G. Sealy Award, among many others. Regularly appears on MSNBC, provides congressional testimony, and was a panellist for President Obama’s Task Force on 21st Century Policing.
