Research & Publications
My research applies basic learning and reinforcement processes to clinical problems of substance use disorders. In double-blind, placebo-controlled laboratory studies, I have examined how the subjective and reinforcing effects of several commonly used drugs (e.g., caffeine, alcohol, cocaine) impact drug taking and risk behavior. I also have experience conducting randomized, controlled clinical trials including: use of motivational incentives (i.e., contingency management) to promote cocaine abstinence in methadone maintenance patients, implementing adjunctive memory training for individuals enrolled in substance use treatment, and assessing a brief, manualized caffeine cessation and reduction program in individuals with problematic caffeine use. My current focus on clinical substance use phenomena is grounded in my past experience in translational behavioral science with humans and nonhumans. All my work shares the common goal of using the principles of reinforcement and behavioral pharmacology to understand, prevent, and treat substance use disorders.
