I am Professor of Health Law, Ethics & Human Rights and Professor of Law at Boston University. My research explores the cross-section of health law and constitutional law with emphasis on health reform (especially Medicaid), federalism, and federal spending power. I am author of two major health law casebooks, several book chapters, and many articles in national and international journals including Stanford Law Review, New England Journal of Medicine, Harvard Law & Policy Review, Boston College Law Review, Yale Journal of Health Policy, Law & Ethics, and Health Affairs. My article, Federalizing Medicaid, was cited by the Supreme Court in the first Affordable Care Act decision, NFIB v. Sebelius. My work also has been cited by the Delaware Supreme Court, federal district courts, and in briefs to the US Supreme Court. I have been interviewed by media that include Bloomberg News, Congressional Quarterly, Washington Post, New York Times, NPR, Huffington Post, National Law Journal, Mother Jones, Law 360, Politico, Vice News, and Modern Healthcare. In 2019, I won the Excellence in Teaching Award (for teaching in the Core) at BU School of Public Health.
