I hold the John G. Tower distinguished chair in international politics and national security as an associate professor at Southern Methodist University (SMU).  My research and teaching interests revolve around U.S. security policy and transatlantic relations, the politics and ethics of military intervention, and multilateral cooperation in international security affairs.

I am the author of Reassuring the Reluctant Warriors: US Civil-Military Relations and Multilateral Intervention, published in 2015 with the Cornell Studies in Security Affairs series. The book argues that America's top-ranking generals, as reluctant warriors who value international burden sharing in the context of military operations, play an underappreciated role in steering U.S. intervention policy toward multilateral engagement. In addition, I have published two books on classical international relations theory: Just and Unjust Military Intervention: European Thinkers from Vitoria to Mill (co-edited with Jennifer Welsh; Cambridge UP 2013), and A Cosmopolitanism of Nations: Giuseppe Mazzini’s Writings on Democracy, Nation Building, and International Relations (co-edited with Nadia Urbinati; Princeton UP 2009). My research has also appeared in a variety of peer-reviewed journals, including Ethics & International Affairs, International Theory, the Journal of Strategic StudiesSecurity Studies, and the Review of International Studies

I have been awarded a PhD from Columbia University (with distinction) and a Master's degree from the London School of Economics and Political Science. I have held numerous fellowships, including at Harvard's Kennedy School of Government, the Brookings Institution, the European University Institute, the Fondation Maison des Sciences de l’Homme in Paris, and the Free University of Berlin. Before moving to SMU, I was a tenured faculty member at the University of Cambridge in the UK.
