She earned her BS from Union College, an MPH from The Johns Hopkins School of Hygiene and Public Health, and an MD from Johns Hopkins University School of Medicine. One of Dr. 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.
