David Squier J. is a criminologist at the Center for Homicide Research. As a former deputy sheriff in California and police officer in Minnesota, he is interested in policing and the role of police in a democratic society, especially with regard to police-community relationships, including the impact of police legitimacy on police effectiveness, and how procedural justice and implicit bias training can begin to improve legitimacy in some communities suffering from a significant schism between its members and police.

Mr. J’s scholarship extends beyond criminological etiology, and he seeks to conduct research that has practical implications for informing policy. His research has included comparing police practices cross-nationally, homicide and serious violence, collective efficacy, social network analysis, and group violence intervention. David’s publications appear in Policing and Society, The Qualitative Report, The Police Chief, Minneapolis Star Tribune and chapters in academic book volumes relating to gang and police research. David also serves as an adviser on a NIJ-funded study at Harvard University which uses public health datasets to analyze legal-intervention shootings, and is a member of the American Society of Criminology and its Division of Policing. He has taught undergraduate criminology, policing, human trafficking, law and society, and has been an invited lecturer in epidemiology.

David earned his bachelor’s degree in legal studies from California State University, Long Beach, his master’s degree in criminal justice from Metropolitan State University and was a doctoral student at Northeastern University’s School of Criminology and Criminal Justice.

As a scholar with practical experience and relationships with leaders in criminal justice, David is well aware of what students need to learn both in the classroom and beyond to help them improve their opportunities as a prospective candidate in this field.
