Karen M. Tani L’07, PhD’11 is a scholar of U.S. legal history, with broad interests in social welfare law, administrative agencies, and the role of rights in the modern American state.

Her current research is about the history of disability law in the late twentieth century. She teaches Torts, American Legal History, and Law & Inequality, as well as classes in the History Department, where she is jointly appointed.

Tani is the author of States of Dependency: Welfare, Rights, and American Governance, 1935-1972 (Cambridge University Press, 2016), which won the 2017 Cromwell Book Prize from the American Society for Legal History.

Goldberg Award for Distinguished Scholarship in Education Law from the Education Law Association); “Administrative Equal Protection: Federalism, the Fourteenth Amendment, and the Rights of the Poor,” Cornell Law Review (2015) (selected for presentation at the 2014 Harvard/Stanford/Yale Junior Faculty Forum); “States’ Rights, Welfare Rights, and the ‘Indian Problem’: Negotiating Citizenship and Sovereignty, 1935-1954,” Law and History Review (2015); and “Welfare and Rights before the Movement: Rights as a Language of the State,” Yale Law Journal (2012). Her work has also been published or is forthcoming in the Disability Studies Quarterly, the Michigan Law Review, the University of Pennsylvania Law Review, the American Journal for Legal History, and Publius: The Journal of Federalism, among other outlets.
