Orestis Panagiotou is a physician-scientist with experience in evidence-based medicine, clinical epidemiology, and research methodology. He received his MD and PhD in Epidemiology from the University of Ioannina in Greece and completed a post-doctoral fellowship in Epidemiology and Biostatistics at the National Cancer Institute (NCI) in Rockville, MD.
His research interests include comparative effectiveness and safety research and risk prediction, particularly in the context of routinely-collected health data. To this end, Orestis works on both applied and methodological problems in the following research areas:
He is a member of the Eastern Cooperative Oncology Group-American College of Radiology Imaging Network (ECOG-ACRIN) Cancer Research Group, one of only four cooperative networks in the US which are currently funded and supported by the NCI.
His research has been published in highly selective journals such as JAMA, Annals of Internal Medicine, New England Journal of Medicine, BMJ and others.
Collectively, his work has directly informed decisions and policies by federal and state policy-makers, regulators, purchasers, and payers including the Centers for Medicare & Medicaid Services (CMS); the Center for Devices & Radiological Health (CDRH) at the Food & Drug Administration (FDA); and the Office of Governor Gina M. Raimondo, the Office of the Health Insurance Commissioner, and the Executive Office of Health and Human Services (all in the state of RI).
