Jovita Murillo

Read Jovita's Bio


Dr. Murillo received a Doctorate in Public Health (DrPH) from Claremont Graduate University. Her research interests involve exploring the intersectionality between social determinants of health and health disparities. Her long-term research goals are to develop policies that can address the social needs of minority populations within health systems. This includes developing a comprehensive understanding of how policies, protocols, and practices that exist in society perpetuate structural determinants in health systems. Intermediary determinants of health further explain how these structural mechanisms lead to adverse health outcomes and other challenges for minority populations. Dr. Murillo hopes to address the science-practice gap by targeting interventions that can be used to advance measures to protect, preserve, and promote the health and safety of minorities.
