Phillip A. Goff is an Associate Professor of Social Psychology at the University of California, Los Angeles, currently on leave as a Visiting Scholar at the Harvard Kennedy School. He is the co-founder and president of the Center for Policing Equity, and an expert in contemporary forms of racial bias and discrimination, as well as the intersections of race and gender. Dr. Goff has conducted work exploring the ways in which racial prejudice is not a necessary precondition for racial discrimination. That is, despite the normative conceptualization of racial discrimination—that it stems naturally from prejudiced explicit or implicit attitudes—his research demonstrates that contextual factors can facilitate racially unequal outcomes. Most recently, Dr. Goff led the CPE in becoming one of three Principal Investigators for the U.S. Department of Justice's National Initiative for Building Community Trust and Justice. The National Initiative will contribute information to another major project by the CPE, the National Justice Database, the first national database on racial disparities in police stops and use of force. Dr. Goff’s model of evidence-based approaches to fairness has been supported by the National Science Foundation, Department of Justice, Russell Sage Foundation, W.K. Kellogg Foundation, Open Society Foundations, Open Society Institute-Baltimore, Atlantic Philanthropies, William T. Grant Foundation, the COPS Office, the Major Cities Chiefs Association, the NAACP LDF, NIMH, SPSSI, the Woodrow Wilson Foundation, the Ford Foundation, and the Mellon Foundation among others. Dr. Goff was a witness for the President’s Task Force on 21st Century Policing and has presented before Members of Congress and Congressional Panels, Senate Press Briefings, and White House Advisory Councils.

Dr. Haviland’s research focuses on causal analysis with observational data and analysis of longitudinal and complex survey data applied to policy issues in health and criminology. For example, she recently led a team of researchers assessing the effects of high deductible account-based health insurance plans on health care costs, use, and disparities in the most comprehensive study on the topic to date. Other health policy work involves assessing mechanisms for health disparities for Medicare recipients and exploring connections between patient safety and recent reductions in medical malpractice claims. An example of her work in criminology is methodological work extending group-based trajectory modeling (semi-parametric longitudinal mixture models) to address causal questions with application to assessing the effect of gang membership on violent delinquency. She served on the National Research Council panel tasked with assessing the research evidence on whether there is a deterrent effect of the death penalty. This and other work of Dr. Haviland’s has been published in journals such as Psychometrika, Psychological Methods, Review of Economics and Statistics, Journal of Human Resources, Survey Methodology, Criminology, Health Affairs, Health Services Research, Medical Care, and the Forum for Health Economics and Policy.
