My main research area explores questions of international justice, in particular questions relating to just war and humanitarian intervention, global governance, human rights and international law. I am particularly interested in normative or moral questions and their impact on, and relation to, questions of politics and law. I have been concerned with questions of how we should conceive of the relation between ethics and international politics (Ethics Justice and International Relations, Routledge 2001) and have just published The Politics of International Law and International Justice with Dr Edwin Egede. I also have broader interests in contemporary political theory and the history of political thought and along with colleagues in the political theory research unit, have recently collaborated on projects on multiculturalism (Multiculturalism, Identity and Rights Routledge 2003) and questions of justification in moral theory (Principles and Political Order: The Challenge of Diversity Routledge 2006) and the nature of evil in contemporary political theory (EUP 2011). I am currently working on questions of just war theory,global law and distributive justice.
