Subject groups/Research projects
Departments and Institutes
I specialize in the history of American foreign relations. More specifically, my teaching and research interests lie in the intersections between the national and the international, the foreign and the domestic, including the influence that domestic politics and culture—particularly religion—have had on the conduct of U.S. foreign policy. I am currently working on two major projects: I am writing a book on the idea of “national security” in American history, which will be published by Harvard University Press; and, with series editor Lien-Hang Nguyen, I am editing Vol. 2 of the forthcoming 3-volume Cambridge History of the Vietnam War.
I am happy to supervise MPhil and PhD dissertations on most aspects of American political, religious, and foreign relations history in any period since the Civil War.
In Part I, Paper 24 (US History since 1865). In Part II, Paper 26 (The American Experience in Vietnam, 1941-1975).
Other Professional Activities
In addition to my scholarly work, my writing has appeared in the Toronto Globe & Mail, History Today, the Boston Globe, Religion & Politics, Politico, the TLS, and ForeignAffairs.com. I sit on the editorial boards of Diplomatic History, History, and Diplomacy & Statecraft, and was elected to serve on the Executive Council of the Society for Historians of American Foreign Relations (SHAFR).
