Welcome! I am an Assistant Professor of Political Science at Colgate University. I am also an incoming Co-Editor of International Studies Perspectives. My research investigates the impact of individual leaders on international security and foreign policy. I have a special interest in how leaders use the tools of coercion to achieve their foreign policy goals, how leaders establish reputations, and how the backgrounds of leaders influence their policy preferences. My book Reputation for Resolve: How Leaders Signal Determination in International Politics (Cornell University Press, Cornell Studies in Security Affairs) examines how new leaders establish reputations for resolve through their statements and behavior. My research is also published in Political Analysis, International Interactions, Political Research Quarterly, and the Journal of Global Security Studies.

My policy relevant writings have been featured on ForeignPolicy.com and The Washington Post's Monkey Cage (I, II, III). I am also a permanent contributor to Political Violence @ A Glance, where I engage in policy analysis of current events and international problems. My media appearances include CNN, the New York Times, War on the Rocks' Warcast, and the POTUS radio show.
