Michael Chaple, PhD Investigator

email Michael

Michael Chaple, Ph.D, a criminologist, is the Director of the Center for the Integration of Research and Practice (CIRP) at NDRI, Inc., where he worked for the past 18 years. The mission of CIRP is to integrate science and service in the treatment of substance abuse, HIV and related disorders, especially psychological disorders and criminal behavior. CIRP seeks to advance the knowledge dissemination and technology transfer efforts of NDRI and to promote the use of "best practices" in the service field. Dr. Chaple’s line of work reflects the growing need to "bridge the gap" between research and practice by developing research studies relevant to emerging issues in the field and by translating research findings into practical guidelines for immediate clinical application. As Director of CIRP, Dr. Chaple has been the Project Director on numerous NIDA-funded multi-site clinical trials.

Currently, CIRP is participating in a study funded by the National Institutes on Drug Abuse (NIDA; R01-DA038146), through a subcontract with RTI International (Garner, PI), which is a a multisite randomized trial (conducted as part of a type II effectiveness-implementation trial) testing the effectiveness of a motivational interviewing-based brief intervention for substance use as an adjunct to usual care in AIDS service organizations (ASOs). Prior to that Dr. Chaple was the PD on a NIDA-funded study, “Computerized Psychosocial Treatment for Offenders with Substance Use Disorders” (RC2-DA002-8967), a randomized controlled trial in 10 prisons across 4 states that evaluated the effectiveness of a computer-based substance use treatment program (the Therapeutic Education System) for incarcerated offenders, examining its impact on recidivism, relapse to drug use, and HIV drug- and sex-related risk behaviors. A third project, “Criminal Justice Drug Abuse Treatment Studies (CJ-DATS)” (1U01DA16200), established a nationwide research system designed to evaluate and test interventions in multi-site studies that address systems-level interventions and issues related to integrating public health and public safety approaches for drug-using offenders. A fourth project, “Criminal Justice Drug Abuse Treatment Studies 2 (CJ-DATS2)”, (2U01DA016200-06A1), tested implementation strategies that could result in sustained delivery of SUD treatment services in three distinct domains: (1) medication-assisted treatment for offenders transitioning to the community; (2) HIV continuum of care (i.e., screening and counseling, risk reduction interventions, ARV treatment adherence from prison or jail into the community); and (3) screening/assessment processes to identify offenders with drug use and related health problems and to inform their treatment planning and re-entry process.

Dr. Chaple received his Ph.D. from Rutgers University and is an Adjunct Professor at St. John’s University.

Dr. Brian Edlin has been engaged in research on emerging issues in infectious diseases for 25 years, including 20 years conducting community-based research with people who inject illicit drugs (PWIDs). The goals of this work are to develop a multidimensional understanding of the factors associated with health and illness in these populations, and to develop and evaluate policies and interventions to improve their health. This research examines social, structural, behavioral, and biological factors associated with health conditions among PWIDs — including HIV, hepatitis B and C, other viral infections, tuberculosis, abscesses, heroin overdose, and other causes of morbidity and mortality in substance-using populations. Dr. Edlin’s research team has developed or evaluated pioneering interventions including needle exchange, street-based hepatitis B vaccination, street-based abscess care, and naloxone distribution to prevent fatal heroin overdose.

Two community-based studies currently underway in New York focus on how and why the hepatitis C virus (HCV) continues to spread among people who inject illicit drugs despite access to needle exchange, and on overcoming the barriers to access to hepatitis C treatment in people currently injecting illicit drugs. The Swan Project is a study of the clinical, behavioral, virologic, and immunologic characteristics of acute HCV infection among high-risk young persons who inject illicit drugs. The Collaborative Hepatitis Outreach and Integrated Care Evaluation Study (CHOICES) is a randomized trial of a novel multidisciplinary, integrated care program carried out in collaboration with a community-based needle exchange program in Harlem that provides antiviral therapy for hepatitis C to persons who inject illicit drugs.

In the policy arena, Dr. Edlin has been at the forefront of efforts to win access to hepatitis C treatment for illicit drug users. He was the first to publicly and prominently challenge the NIH recommendation to withhold hepatitis C treatment from active illicit drug users. The following year, the NIH invited him to address its Consensus Development Conference as an expert speaker on hepatitis C in injection drug users. The Consensus Panel adopted his recommendations, rescinding its recommendation against treating drug users for hepatitis C and recommending hepatitis C prevention, testing, and treatment programs for injection drug users and incarcerated persons.

Dr. Edlin has also had 20 years’ experience as a research mentor, providing guidance in clinical and epidemiologic research study conceptualization, design, implementation and management, data analysis and interpretation, manuscript development and submission, and grant writing, resulting in more than 25 publications in peer-reviewed journals first-authored by trainees.

Andrew Golub is a Senior Principal Investigator in The Institute for Special Populations Research. He received his Ph.D. in Public Policy Analysis from Carnegie Mellon University. His research focuses on understanding social problems in context with an aim towards developing appropriate public policy responses. His studies have examined trends in drug use, the larger context of use, causes and consequences of use, and the efficacy of policies and programs as well as associated issues related to violence, crime, policing, poverty, and families. In the course of his work, Dr. Golub has developed a descriptive model for the dynamics of drug epidemics. Epidemics like other diffusion phenomena tend to progress from incubation within a limited social context through a period of rapid expansion to a plateau of widespread use and finally into an extended decline phase. Dr. Golub has used this framework to analyze the Heroin Injection Epidemic which peaked in the 1960s and early 1970s, the Crack Epidemic with peaked in the mid to late 1980s, the Marijuana/Blunts Epidemic which emerged in the 1990s, the Methamphetamine Epidemic that may be starting to draw to a close in the 2010s, and the currently prevailing epidemic in prescription opioid and heroin use. Dr. Golub has also examined the gateway phenomenon and identified ways in which drug use pathways vary with cultural trends over time and across individual circumstances.
