Research Interests

Dr. Broyles’s research seeks to understand how the different contexts in which we live – e.g., neighborhood, work, parks, social networks – shape our disease risks and health outcomes. Within the broad area of physical activity and obesity, her research is focused on understanding the contextual influences on health and behavior and on longitudinal changes in them, in both observational and interventional settings. Dr. Broyles has worked in public health for over 20 years, and her 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 also on the graduate faculty of the LSU Health Sciences Center, holding an adjunct position in the LSUHSC School of Public Health’s Behavioral and Community Health Sciences Program, where she teaches doctoral courses and mentors several PhD students.
