Research Summary

I am a practicing general internist and a researcher in tobacco control with a focus on populations experiencing homelessness. I am formally trained in a variety of methodologies, including implementation sciences, descriptive epidemiology using national longitudinal and cross-sectional data, policy analysis, randomized controlled trials, qualitative and mixed methods research. My intervention research stems from collaborations with community organizations. As principal investigator of two prior grants from the Tobacco Related Disease Research Program (TRDRP) , I collaborated with homeless shelters and supportive housing to implement interventions to increase access to smoking cessation services and smoke-free policies among homeless adults. My current work, funded by the NCI, includes a cluster randomized controlled trial of a smoke-free home intervention in 20 permanent supportive housing sites in the San Francisco Bay Area. We have started recruiting participants for another randomized controlled trial of a contingency management smoking cessation intervention for people experiencing homelessness. My current work also involves delivery of system-level interventions for smoking cessation, integrated within the electronic health record of safety-net health systems.
