Research Interests

Dr. Walker is a health services researcher trained in research methodology and health disparities. Her research focuses on reducing and eliminating health disparities by addressing social determinants of health, with particular emphasis on psychosocial, behavioral, and community factors influencing low income populations. Dr. Walker is particularly interested in incorporating social determinants of health such as stress and food insecurity into interventions that improve health outcomes for low income individuals with diabetes. In addition, she is interested in global health effort, particularly in the areas of indigenous health, building health care capacity in low resource environments, and incorporating social determinants of health into health care efforts to improve outcomes for non-communicable diseases.

Dr. Walker has expertise in analytical techniques focused on understanding mechanisms and pathways, including confirmatory factor analysis, path analysis, and structured equation modeling. She also has training in health behavior, health services theory, health economics, and implementation science. Her ongoing work is funded through the American Diabetes Association and the NIH National Institute of Minority Health and Health Disparities (NIMHD) focused on addressing food insecurity in African Americans with diabetes.
