is a director of ReThink Health for the Fannie E. Rippel Foundation and a visiting scientist at the MIT Sloan School of Management. With an educational background that combines cultural anthropology, behavioral science, and systems science, Milstein concentrates on challenges that involve large-scale institutional change and the need to align multiple lines of action. He led the development of the ReThink Health Dynamics model and a suite of regionally-configured simulations that are used by leaders across the country to explore the likely health and economic consequences of policy scenarios. From 1991 to 2011, Milstein worked at the Centers for Disease Control and Prevention, where he founded the Syndemics Prevention Network, chaired the agency's Behavioral and Social Science Working Group, and was coordinator for a wide range of new initiatives. He was the principal architect of the CDC's framework for program evaluation and published a monograph entitled Hygeia's Constellation: Navigating Health Futures in a Dynamic and Democratic World, recommended as "required reading for all health professionals." Milstein has led several award-winning teams that bring greater structure, evidence, and creativity to the challenge of health system change. He is a cofounder (with Patty Mabry) of the NIH Institute on Systems Science and Health, and a codeveloper of several other widely used health policy simulation models including HealthBound and the Prevention Impacts Simulation Model. He has received CDC's Honor Award for Excellence in Innovation, the Applied Systems Thinking Prize from ASysT Institute, as well as Article of the Year awards from AcademyHealth and the Society for Public Health Education. Milstein holds a B.A. in cultural anthropology from the University of Michigan, an M.P.H. from Emory University, and a Ph.D. in interdisciplinary arts and sciences with a specialization in public health science from Union Institutes and University.
