Professional Interests

My main professional interests are in substance abuse treatment, medication adherence, incentive-based intervention, and the experimental analysis of behavior.  My work can be broadly classified as contingency management.  The primary focus of my research is to create sustainable long-term interventions for promoting healthy behaviors in low-income populations.

My recent completed projects show that employment-based abstinence reinforcement is an effective long term maintenance intervention in refractory methadone patients, and that employment-based reinforcement can promote adherence to naltrexone pharmacotherapy in heroin dependent adults living in poverty.

Current projects include further investigation of employment-based contingencies and naltrexone pharmacotherapy, the development of a pre-trial diversion program that features employment-based abstinence reinforcement, and the development of a wage subsidy program designed to simultaneously increase community employment while reinforcing drug abstinence in methadone patients.
