I am a statistician faculty member of the Departments of Medicine as well as Preventive and Restorative Dental Sciences. I am also a Director of Data Coordinating Centers serving two NIDCR-funded national consortia: the Early Childhood Caries Collaborating Centers (EC4) as well as the Multidisciplinary and Collaborative Research Consortium to Reduce Oral Health Disparities in Children (MCRC for OHDC).
My research focuses on prevention and health behaviors via randomized trials, quasi-experiments, and longitudinal observation studies, within diverse national and international populations. I have been investigator, principal statistician, and/or statistical/methodological mentor of over 70, largely federally funded, centers, projects, and career development awards.
