Research/Academic Interests
Dr. Keegan is a cancer epidemiologist with primary research interests in studies of cancer outcomes, health disparities and cancer survivorship. She has undertaken numerous studies with population-based cancer registry data in the United States, both alone and linked to other administrative and clinical databases, to understand patterns of cancer treatment and outcomes. Dr. Keegan has also been involved with multiple studies examining patient experiences with cancer and patient-reported outcomes after cancer diagnosis. A focus of her research is in adolescent and young adult (AYA) oncology where her research has documented sociodemographic disparities in stage at diagnosis, treatment, access to specialized cancer center care, late effects and survival.
