I teach courses in ethics, social and political philosophy, political economy, philosophy of the social sciences, and feminist theory. My research focuses on democratic theory, equality in political philosophy and American law, racial integration, the ethical limits of markets, theories of value and rational choice (alternatives to consequentialism and economic theories of rational choice), the philosophies of John Stuart Mill and John Dewey, social epistemology, and feminist epistemology and philosophy of science. I am currently working on the history of egalitarianism, with a special focus on the social epistemology of moral learning, taking the history of abolitionism as a central case study. I designed and was the first Director of the Program in Philosophy, Politics, and Economics.
