His research interests lie in social and political philosophy (political authority, political obligation, global justice, transnational democracy), moral philosophy (Kant and the Kantian tradition in ethics and metaethics), and Habermas and the Frankfurt School tradition of "critical social theory." His recent scholarly publications have addressed Habermas and democratic law; Rorty and liberal democracy and religion; and Rawlsian critical theory and the World Trade Organization (forthcoming). He received his PhD in 2009 from Northwestern University.
