Siran Koroukian, PhD
Professor
CWRU School of Medicine
Siran M. Koroukian, PhD is Professor of Population and Quantitative Health Sciences at CWRU School of Medicine. Dr. Koroukian’s research is informed by her early career in nursing and health policy focused on Ohio’s Medicaid program and the population that it serves. Much of her academic work bridges between public health and big data/informatics to uncover disparities in access and outcomes, with a focus on chronic illnesses, including cancer and epilepsy, especially among older adults. Her studies on cancer and aging highlight the importance of developing methods to identify adults with multimorbidity (MM), and underscore the importance of defining MM as not only co-occurrence of chronic conditions, but also of functional limitations and geriatric syndromes. Central to her work are data originating from large databases, such as Medicare and Medicaid, tumor registries, clinical assessments, vital records, and more recently, electronic health records.
