She is specifically interested in using experimental methods to examine whether police programs and policies work and whether they are fair. Dr. Huff is a National Institute of Justice Law Enforcement Advancing Data and Science (NIJ LEADS) Academic who has partnered with police agencies across the U.S. to evaluate programs including violence reduction strategies, intelligence-led approaches to gun crime, use of force training, and body-worn cameras. She is currently working with the Tacoma Police Department to examine the impact of gun crime identification and investigations technology. She is also working on a statewide evaluation of police officer retention efforts in Ohio.
Secretary/Treasurer: Dr. Kyle McLean

Dr. McLean works with law enforcement officers across the country to assess and recommend evidence-based practices for police departments. Dr. McLean is leading a team of researchers that was recently awarded more than $892,000 from the National Institute of Justice to evaluate a police de-escalation training program.
Executive Counselor: Dr. Colleen Berryessa
Dr. Colleen Berryessa is an Associate Professor at the Rutgers University School of Criminal Justice. Her research, utilizing both qualitative and quantitative methods, considers how psychological processes, perceptions, attitudes, and social contexts affect the criminal justice system, particularly related to courts, sentencing, and forms of punishment broadly defined. She primarily examines these issues, using interdisciplinary methodologies, in relation to three areas: 1) how psychological and social phenomena influence public perceptions, support, and subsequent consideration of practices, policies, and the philosophical foundations surrounding sentencing; 2) how psychological and social phenomena influence the discretion and decision-making of criminal justice actors during the sentencing process; and 3) how psychological and social phenomena bear on motivations for and effects of expanded forms of legal and social punitiveness beyond the formal punishment stages of the criminal justice system. Colleen received her Ph.D. in Criminology from the University of Pennsylvania. Before Penn, she graduated from Harvard University with a B.A. in Government and Mind, Brain, and Behavior, and she served as a CIRGE research fellow at Stanford University.
Executive Counselor: Dr. Lois James
Lois James is the Assistant Dean of Research and the PhD Program Director in the Washington State University (WSU) College of Nursing. She is also the Director of the Sleep and Performance Research Center (SPRC) at WSU, where she focuses on the impact of sleep loss, fatigue, stress, and bias on performance and safety in shift workers such as police officers, firefighters, health care personnel, and military personnel. She has received multiple honors and awards for her work and is internationally recognized as a leading expert in her field. She specializes in developing, implementing, and evaluating fatigue risk management, sleep education, and anti-bias training programs. She is the founding Director of Counter Bias Training Simulation (CBTsim), a simulation-based anti-bias training program that has been found to improve the outcomes of police-community member encounters and promote community perceptions of police fairness. Dr. James’s work has been published extensively in academic journals, practitioner magazines, and mainstream media such as the New York Times and the Washington Post.
Executive Counselor: Dr. Sue-Ming Yang
Sue-Ming Yang is an associate professor in the Department of Criminology, Law and Society at George Mason University. She received her PhD from the Department of Criminology and Criminal Justice at the University of Maryland. She is a Fellow of the Academy of Experimental Criminology.

Prior to her appointment at Mason, she was an associate professor at National Chung Cheng University and received the Young Scholar Award.
Immediate Past Chair: Dr. Jerry Ratcliffe
Jerry focuses on evidence-based policing and crime analysis, and he works with police agencies around the world on leadership, crime reduction and criminal intelligence strategy.
