He holds an A.B. in Philosophy from Princeton University and a Ph.D. in Philosophy from Harvard University. A former fellow at the Safra Center for Ethics at the Kennedy School of Government, he works on issues in moral and political philosophy, particularly as they arise in economic life. He has published articles on the nature of freedom and autonomy, the ethical significance of class, and more democratic alternatives to the Anglo-American model of capitalism. His current research asks whether Rawls's theory of justice has an adequate response to the "consumer culture" critique of capitalist democracy.
