Professional Interests

The underlying theme of my career has been to understand and facilitate human behavior change, particularly behavior change that is fundamental to addiction recovery. Toward that end, much of my research has applied behavioral economic concepts such as delay discounting to decision-making underlying drug addiction. My current research is applying these models to understand the high rates of sexual HIV risk behavior associated with certain abused drugs (e.g., cocaine, methamphetamine, alcohol). Another focus of my research involves laboratory studies determining the behavioral and psychological effects of psychoactive drugs in humans, particularly novel or atypical drugs. This work has examined hallucinogens including psilocybin and salvinorin A (Salvia divinorum), stimulants including cocaine, methamphetamine, nicotine, and caffeine, and various sedatives. Current research with psilocybin is examining its potential for facilitating behavior change. These studies include a trial determining the ability of psilocybin to increase engagement in a meditation program, a trial testing if psilocybin can decrease anxiety and depression in cancer patients, and a study examining psilocybin as an anti-addiction medication for tobacco smoking cessation.
