I am a clinical psychologist and Professor in the Department of Psychiatry at the University of California, San Francisco. In this role I am involved in clinical, research, and training activities. My clinical interests are in individual and group treatment for a variety of mental health issues, including anxiety, depression and addiction. I have extensive experience and expertise in brief treatment and long-term treatment models including cognitive-behavioral, motivational interviewing/enhancement, problem-solving, relaxation training, and 12-step interventions. My clinical and research interests include addressing health and mental health disparities among low-income populations, the LGBT community, and individuals impacted by HIV as well as integrating digital interventions into treatment.
My research focuses on the evaluation of clinical interventions for nicotine dependence, factors predictive of smoking treatment success, and development of Internet-based interventions for health behavior change. Much of my research focuses on populations experiencing tobacco-related health disparities including LGBT individuals, individuals with HIV disease, smokers with drug dependence, and low-income groups. I have conducted clinical trials evaluating the efficacy of internet-based and telephone-based smoking treatment for LGBT cigarette smokers. I recently led a study evaluating the efficacy and cost-effectiveness of smoking cessation treatment provided in HIV clinical care settings. Other work has focused on interventions with depressed smokers and the development of an extended smoking treatment model based on the conceptualization of nicotine dependence as a chronic, relapsing disorder.
