Sara M. St. George, PhD, is an Assistant Professor in the Department of Public Health Sciences at the University of Miami Miller School of Medicine. She received her PhD in Clinical-Community Psychology from the University of South Carolina and has expertise in pediatric obesity and its associated behaviors, including physical activity, sedentary behavior, and diet. Her research interests include developing and testing theoretically-based obesity prevention interventions which integrate multiple influential systems (e.g., family and peers) to promote positive health behaviors in ethnic minority adolescents. Throughout her graduate training, Dr. St. George developed the beginnings of an independent program of clinical research in pediatric obesity prevention and health promotion funded by a diversity supplement grant (NIH R01 DK 067615-02S1) and a pre-doctoral fellowship (NIH F31 HD 066944). This work lead to her receiving the Outstanding Dissertation Award from the Society of Behavioral Medicine. She was recently awarded a NIH K01 early career investigator award to continue to build from and expand her program of research. The goals of this study are to develop and pilot test a family-based intervention that combines the web and smartphone technology for increasing physical activity, decreasing sedentary behavior, and improving quality dietary intake in Hispanic adolescents. Dr. St. George is affiliated with both the Sylvester Comprehensive Cancer Center and the Center on Aging. She currently teaches Qualitative Research Methods in the Master’s and PhD programs within the Department of Public Health Sciences.
