My primary research and clinical interests are substance abuse treatment and HIV-prevention; my current research activities focus on the efficacy of psychological and pharmacological interventions for the treatment of nicotine addiction. A substantial amount of research links cigarette smoking and relapse with negative affect and depression. I am currently involved in a series of studies with Sharon Hall, Ph.D., which examine the efficacy of psychological and pharmacological interventions targeting mood changes in smokers attempting to quit. This work is funded by the National Institute on Drug Abuse (NIDA).

Other interests of mine include research in HIV-prevention and risk reduction, with involvement in the development, implementation, and evaluation of NIDA-funded, community-based, outreach interventions targeting at-risk populations, including injection drug users (IDUs) not in treatment, female sex partners of IDUs, and street youth. My clinical interests include psychotherapy with HIV-impacted persons and the incorporation of risk-reduction activities into psychotherapy and counseling with at-risk individuals.
