Dr. Grace Wang

Dr. Grace Wang, a Principal Research Associate at IMPAQ, focuses on the impact of health programs on health outcomes and costs. She has led mixed methods evaluations for foundations and government agencies. Examples include: a randomized controlled trial of a health access program, key informant interviews and surveys to describe a government and foundation partnership, and propensity score matching to choose physicians to invite to a survey. Dr. Wang’s research has also addressed the cost effectiveness of different testing approaches to identify a hereditary cancer syndrome and health care transitions for youth with disabilities.


Dr. Wang is an expert in mixed method evaluation approaches and applying conceptual models to program evaluation. She designs and conducts environmental scans and systematic literature reviews to examine health topics. Her analytic skills include regression models to analyze survey, administrative, and electronic health record data. Dr. Wang also gathers and analyzes data from key informant interviews and focus groups.


Dr. Wang has worked with private foundations (e.g., Blue Shield of California Foundation, California HealthCare Foundation, Sierra Health Foundation), federal government agencies (e.g., Agency for Healthcare Research and Quality, Centers for Medicare & Medicaid Services, Office of the National Coordinator for Health Information Technology), and local government agencies (e.g., New York City Department of Mental Health and Hygiene, San Mateo County Behavioral Health & Recovery Services).

Prior Experience

Before joining IMPAQ, Dr. Wang was a Principal Researcher at the American Institutes for Research, a Post-doctoral Fellow at the University of California, San Francisco, a Research Associate at the University of Washington, and a Medical Program Specialist with the Washington State Department of Labor and Industries.


Dr. Wang earned her Ph.D. from the University of Washington in Public Health Genetics in 2009, her MPH from The George Washington University, and her BA from the University of Pennsylvania.
