Timothy K. LakeTimothy K. Lake
Associate Director of Health Research; Senior Researcher

Timothy Lake is an associate director of health research and a senior researcher with expertise in the organization of health care services, health care payment reforms, and the measurement of access to and quality of care. His research covers a range of programs, including Medicare, Medicaid, and private sector insurance. His work often combines quantitative and qualitative methods, with a particular emphasis on synthesis of research for use in policymaking.

Lake provides technical assistance, policy analysis, and research support to states and federal agencies in the design, development, and analysis of various payment and delivery system reforms, such as accountable care organizations, pay-for-performance, and bundled payments. He recently directed a study for the National Institute for Health Care Reform examining providers’ efforts to improve care coordination and foster the use of health information technology. He is also co-principal investigator of a study for the New York State Health Foundation to estimate the effects of potential payment reforms on hospital readmissions.

Lake’s other major interest is the development, testing, and use of health care quality and access measures. In prior work, he has advised the Centers for Medicare & Medicaid Services and the Department of Defense/TRICARE on development of performance measures and their uses in feedback reports, quality improvement efforts, and quality and access monitoring systems.

Lake holds a Ph.D. in health services research from the School of Hygiene and Public Health, The Johns Hopkins University.
