Sarah Song is a political theorist with a special interest in democratic theory and issues of citizenship, migration, culture, religion, gender, and race. She teaches courses in contemporary political and legal philosophy, the history of American political thought, and citizenship and immigration law. 

Her first book, Justice, Gender, and the Politics of Multiculturalism (Cambridge University Press, 2007), analyzes theories of group rights for religious and cultural minorities and their intersection with women's rights through a range of case studies in American law and politics. The book was awarded the 2008 Ralph Bunche Award by the American Political Science Association.

More recently she has written articles on the question of boundaries in democratic theory, the rights of noncitizens in liberal democratic societies, and the normative foundations of the modern state's right to control immigration. She is currently working on a book entitled Immigration and the Limits of Democracy.

Born in South Korea, Song immigrated to the U.S. when she was six and attended K-12 public schools in Missouri, Illinois, and New Hampshire. She received a B.A. from Harvard College, an M.Phil from Oxford, and a Ph.D. from Yale. Prior to coming to Berkeley, she was Assistant Professor of Political Science and Affiliated Faculty in Philosophy and Women's & Gender Studies at M.I.T. She has been awarded fellowships from the Woodrow Wilson National Fellowship Foundation and the American Academy of Arts and Sciences. 

She holds a joint appointment with the UC Berkeley School of Law and is currently serving as Director of the Kadish Center for Morality, Law, & Public Affairs, which together with the Political Science and Philosophy Departments sponsors a weekly workshop in moral, political, and legal theory.
