I am Professor of International Relations at the London School of Economics and Political Science. My main teaching and research interests are in the fields of international security and comparative foreign policy, with special focus on American grand strategy and foreign policy. I also write and comment frequently on U.S. party politics and elections and how they shape and are shaped by America’s changing place in the world.
My publications include Politics and Strategy: Partisan Ambition and American Statecraft (Princeton University Press, 2011) and Defining the National Interest: Conflict and Change in American Foreign Policy (University of Chicago Press, 1998), as well as articles in scholarly journals such as International Security, International Studies Quarterly, and Political Science Quarterly and more popular venues like Foreign Affairs, International Herald Tribune, and The National Interest.
Before joining the LSE, I was Professor of Government at the University of Texas at Austin. I have also held visiting positions at Harvard, Princeton, University of California at San Diego, Universidad de Chile, Centro de Investigación y Docencia Económicas (CIDE) in Mexico City, and the Beijing Foreign Studies University, where I was the J. William Fulbright Distinguished Lecturer in American Foreign Policy.
My research has been supported by grants and fellowships from the John D. and Catherine T. MacArthur Foundation, the John M. Olin Foundation, the Ford Foundation, and the Social Science Research Council, among others.
