Paul Shafer is an assistant professor in the Department of Health Law, Policy, and Management at the Boston University School of Public Health, co-director of the Boston University Medicaid Policy Lab, and affiliate faculty of the Boston University Center for Antiracist Research. His research focuses on the effects of state and federal health insurance policy on coverage, health care use, and health equity. He is also an investigator at the Partnered Evidence-based Policy Resource Center at the VA Boston Healthcare System, where his research focuses on veterans' access to care. His big picture interest is in understanding the effect of health and social policies on health and well-being. Do they actually work and are the benefits distributed equitably? If they don't work or have unintended consequences, can we understand why and propose changes?
