Julie Bynum, M.D., M.P.H., Professor of Internal Medicine, Division of Geriatric & Palliative Medicine and Margaret Terpenning Collegiate Professor earned her BS from Union College, an MPH from The Johns Hopkins School of Hygiene & Public Health, and an MD from Johns Hopkins University School of Medicine. One of Bynum’s contributions to the field has been to develop a method of creating “virtual” physician-hospital networks that allows the measurement of care delivered and its outcomes for a population served by a specific group of providers. These networks were used in the conceptual development of the Accountable Care Organization(ACO) legislation.
