I am an expert in the assessment and treatment of tobacco use and heavy alcohol use. I have experience conducting laboratory-based, clinical trials, mixed methods, and implementation and dissemination research. My research has identified important predictors of tobacco and alcohol use and treatment response. I am also developing and testing novel tobacco and alcohol interventions that are integrated with primary/specialty healthcare, promote multiple health behavior change, and incorporate technology with funding from NIH grants. I have held leadership roles for the Society for Research on Nicotine and Tobacco and the Research Society on Alcoholism. I have presented at numerous national and international conferences and am widely cited for my research. In addition to my research activities, I direct the Tobacco Treatment Service at Smilow Cancer Hospital and teach/mentor medical students, residents, and fellows.
