I am interested in a range of issues at the intersection of international relations and political philosophy, such as the responsibility to protect (R2P), mass atrocity prevention, just war theory, human rights, and global justice. Starting in August 2017, I will be a Universitair Docent (Assistant Professor) in International Relations at Leiden University where I will teach in the MAIR program. I am additionally a senior researcher at The Hague Institute for Global Justice. In 2011, I received a Ph.D. in political science from the University of Colorado at Boulder, where I was given the Thomas Jefferson Award. Articles of mine appear in Ethical Theory and Moral Practice, Ethics & International Affairs, Global Constitutionalism, Global Society, and International Theory. My work has received support from The Netherlands Organization for Scientific Research (NWO), George Washington University, and elsewhere. I am additionally affiliated with the European Center for the Responsibility to Protect, the Global Governance Institute, and the Canadian Center for the Responsibility to Protect. I have enjoyed teaching courses on human rights, political theory, international relations, comparative politics, and environmental politics.
