Greg Peterson

Senior Fellow

Greg Peterson has technical and substantive expertise in the effectiveness of federal and state value-based payment and delivery reforms; studying approaches for improving the delivery of hospital and primary care and assessing their effectiveness; and approaches for improving primary prevention and population health.

Peterson currently serves as the project director of a multiyear evaluation of the Maryland Total Cost of Care Model. This project is estimating the effects of statewide commitments to cost and quality goals—combined with hospital all-payer global budgets, primary care investments, and other incentives—on cost and quality of medical care throughout Maryland. The project uses interviews, surveys, and program data to identify what might be driving observed model effects. In addition, he is the project director for the evaluation the Million Hearts Cardiovascular Disease Risk Reduction Model, a randomized trial testing whether paying providers for measuring and reducing their patients’ cardiovascular disease risk succeeds in reducing first-time heart attacks and strokes. Peterson also led the evaluation of the CMS Health Care Innovation Awards, which assessed whether and how different types of primary care delivery reforms improved quality and efficiency of care.

Before joining Mathematica in 2008, Peterson served as an analyst for the Government Accountability Office. He holds a Ph.D. in health policy from the School of Public Policy and Administration at George Washington University and an M.P.A. from the Woodrow Wilson School of Public and International Affairs at Princeton University.
