How We Make a Difference:
The DeMatteo Lab focuses on conducting social science research that can be used to inform practice and policy in the criminal justice system, particularly as those practices and policies relate to offenders with substance use and/or mental health problems. By examining juror and judicial decisions in criminal justice contexts, evaluating the effectiveness of novel criminal justice interventions, and studying how courts use social science evidence, the DeMatteo Lab is contributing to the continued development of the criminal justice system. Through collaborations with a number of criminal justice entities, our work is designed to promote the consideration of social science research by courts, legislatures and policymakers.
