Karen M. Tani 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. The book sheds new light on the nature of modern American governance by examining legal contests over welfare benefits and administration in the years between the New Deal and the modern welfare rights movement.
