My research interests include violence, corrections, substance abuse treatment, and organizational change in both adult and juvenile settings. I am author of Counties in Court: Jail Overcrowding and Court-Ordered Reform (Temple University Press, 1995), Criminal Justice Policy and Planning, with Philip Harris (Elsevier, 2013, 4th Ed.), and Criminal Violence: Patterns, Causes and Prevention, co-authored with Marc Riedel (Oxford, 2015, 4th Ed.). I am currently Co-PI on JJ-TRIALS (Juvenile Justice - Translational Research on Interventions for Adolescents in the Legal System), a national multi-site study (National Institute on Drug Abuse, 2013-2017) to investigate and improve implementation of evidence practices for drug-involved youth in the juvenile system. I was Co-Investigator on CJ-DATS2 (Criminal Justice Drug Abuse Treatment Systems), a national, collaborative research project (National Institute on Drug Abuse, 2009-14). Key research questions addressed organizational and systems issues related to implementation of effective drug treatment and other services in adult criminal justice settings. I was Lead Researcher for our research center on two of three multisite protocols: Medication Assisted Treatment Implementation in Community Correctional Environments (MATICCE), and the Organizational Process improvement intervention (OPII). I've been PI on several other large, multi-site research projects conducted as part of a long term research partnership with the PA Dept. of Corrections which began in 1998 and continues to the present. Funded projects have included: "A Multi-Site Evaluation of Prison-Based Drug Treatment: A Research Partnership Between the Pennsylvania Department of Corrections and Temple University" (Pennsylvania Commission on Crime and Delinquency; 2005-08); "Evaluation of Drug Treatment Programs at the State Correctional Institution (SCI) at Chester: A Partnership Between the Pennsylvania Department of Corrections, Gaudenzia, Inc., and Temple University" (National Institute of Justice, 2002-06); "Evaluation of Prison based Drug Treatment in Pennsylvania: A Research Collaboration Between the Pennsylvania Department of Corrections and the Center for Public Policy at Temple University" (National Institute of Justice, 2000-02); and "Building An Effective Research Collaboration Between the Center for Public Policy at Temple University and the Pennsylvania Department of Corrections" (National Institute of Justice, 1998-2000). Other funded studies include “Building a Culture and Climate of Safety in Public Schools: School-Based Management and Violence Reduction in Philadelphia” (National Institute of Justice, (1993-95) and "Reducing Over-Representation of Minorities in the Juvenile Justice System” (Pennsylvania Commission on Crime and Delinquency, 1994-96). Service to the community includes volunteer participation on the Philadelphia Mayor`s Reentry Task Force and the Philadelphia Children`s Round Table (chaired by the Philadelphia Family Court President). I also serve on the Editorial Advisory Board for the Prison Journal, the oldest, peer-reviewed journal publishing research on adult and juvenile confinement, treatment interventions, and alternative sanctions.
