Cleo A. Samuel-Ryals is a health services researcher with expertise in cancer care inequities, palliative and supportive care, and health informatics. She is particularly interested in disentangling the multilevel sources (i.e., patient-, provider-, and health care system-level) of disparities in palliative and supportive cancer care using mixed methods (i.e., quantitative and qualitative data analysis) and addressing such inequities through system-level approaches that leverage health informatics tools.
