    Research Summary

    I am interested in the human behavioral pharmacology of abused drugs, particularly cannabis (marijuana) and nicotine. My research focuses on the consequences of stopping heavy cannabis or tobacco use and the investigation of medications that can help improve success for individuals trying to quit. I also have interest in investigating novel ways to apply behavioral modification techniques to the treatment of drug abuse problems.
