I am Chair of the Department of Philosophy at the University of Wisconsin – Milwaukee. I previously taught in the Department of Philosophy, Trinity College Dublin (2005-2008), and in the Introduction to the Humanities Program at Stanford University (2002-2005). My research focuses on various issues related to the account of justice and legitimacy known as ‘political liberalism’. (I sometimes refer to my work as 'Rawls plumbing'.) I am a Canadian citizen.
