Biography & Expertise

Stephanie Broyles, Ph.D. is currently Associate Professor of Research and director of the Contextual Risks Factors laboratory at LSU’s Pennington Biomedical Research Center in Baton Rouge, Louisiana. She has been on the faculty of LSUSHC School of Public Health since 2004, holding an adjuct faculty position since 2008. Dr. Broyles has worked in public health for nearly 20 years, and during this time her research has shifted from an early interest in HIV/AIDS epidemiology to a focus on the epidemiology of physical activity and obesity, primarily in pediatric populations. Within this area, her research also seeks to understand contextual (e.g., neighborhood, school, policy) influences on these health and behavioral targets and on longitudinal changes in them, in both observational and interventional settings. Her research was featured in the 2012 HBO documentary series, “The Weight of the Nation.” Dr. Broyles’s work relies heavily on community engagement, and frequently integrates research and service. She brings this approach to her work as co-Director of the Community Outreach and Engagement Resource Core for the Louisiana Clinical and Translational Science Center, a collaboration among all major academic, research, and health care institutions in Louisiana. Methodologically, she has expertise in investigating environmental determinants of health using spatial methods and geographically-linked variables, as well as in multilevel statistical analysis, and she enjoys collaborating on research projects that use novel analytic or study-design techniques. In 2016, Dr. Broyles was awarded the Founder’s Award by the Louisiana Public Health Association, which honors significant achievement in research in public health by a Louisiana resident. Dr. Broyles is available to advise or mentor interested Ph.D. students.
