The overarching goal of our team’s epidemiologic research program is to understand how various behaviors, biological attributes, and social circumstances influence health and disease distributions, often inequitably, across populations. Application of such knowledge aims to inform future public health practices, health policies, and clinical guidelines that elevate the health of patients and vulnerable communities, both locally and worldwide. We strive for these goals through several recent and ongoing projects, such as: (1) A cohort study of conventional and alterative smokeless tobacco use among adolescents in rural California, including psychosocial influences of behavior and resultant nicotine and carcinogen exposures; (2) Investigations of early-life experiences and infant feeding behaviors in relation to childhood oral health in California and Brazil; (3) Evaluating clinical adoption and the effectiveness of patient-tailored caries-preventive therapies for adult and pediatric dental patients.
