Research Interest/Specialty

My primary research interest is in the design, evaluation and dissemination of evidence-based tobacco cessation programs. My secondary research interest is in the etiology of tobacco use in underserved populations, particularly the co-use of tobacco with other tobacco and nicotine containing products.
