Dr. Polsky, a national leader in the field of health policy and economics, has dedicated his career to exploring how health care is organized, managed, financed, and delivered, especially for low-income people. His own research has advanced our understanding of the cost and quality tradeoff of interventions whether they are changes to large federal programs or local programs.  His most recent work focuses on how to provide access to quality health care in low-resource settings with a particular interest in narrow provider networks.
