About Katharine

Katharine (Kate) Bradley studies health insurance coverage and access to care, with a particular focus on low-income populations and Medicaid.

Bradley currently leads a multistate, mixed-methods evaluation of section 1115 Medicaid expansion demonstrations and advises the Centers for Medicare & Medicaid Services on state-specific evaluation design and monitoring requirements for these demonstrations. She is also studying the implementation of the Comprehensive Primary Care Plus initiative by medical practices and has contributed to research on community-based care management, community paramedicine, and care coordination. 

Before joining Mathematica, Bradley worked as the legislative liaison for Idaho Medicaid and as the state director of Idaho’s Children’s Health Insurance Program (CHIP). She authored several pieces of state legislation that established Medicaid reforms, including a beneficiary engagement program. She also directed a federally funded policy development project that spearheaded an expansion of Idaho’s CHIP and the creation of a premium assistance program authorized through a section 1115 waiver. Bradley was a 2004–2005 Packer Policy Fellow in the Australian Department of Health and Ageing, where she evaluated a private health plan monitoring policy.

Bradley’s work has been published in the Journal of Health Politics, Policy and Law and the Journal of Public Policy. She holds a Ph.D. in health services organization and policy and political science from the University of Michigan and an M.B.A. from the University of Washington.
