The focus of my research is international relations, specifically international security. In particular, much of my research is in three primary areas: deterrence, recurrent conflict, and strategic studies. My current research focuses largely in the area of strategic studies. I have examined topics such as the impact of initiative on military effectiveness, the importance of Clausewitz’s concept of centers of gravity for war outcomes, and the relationship between past experiences with either counterinsurgency or conventional warfare and war outcomes of the other type of conflict. My deterrence research focuses on improving our understanding of the dynamics of deterrence through rigorous empirical testing, formal theory building, and policy application. In particular, my research has focused on a consistent formal theory of deterrence, perfect deterrence theory. I have tested the theory using both quantitative analyses and case-studies; further developed the theory, particularly in the areas of three-party games and endogenous stakes; and applied the theory to the understanding of policy questions, particularly with regard to national missile defense. The final primary area of my research involves improving our understanding of recurrent conflict between states. My primary argument is that recurrent conflict can best be understood by assessing the ability of deterrence to stabilize peace following a conflict. I have made this argument through a series of articles, arguing that imposed settlements are more stabilizing than negotiated settlements or disputes ending without a settlement—contrary to the previous conventional wisdom. I am the author of Understanding General Deterrence: Theory and Application (Palgrave Macmillan, 2011) and International Conflict: Logic and Evidence (CQ Press, 2015), and my work has been published in journals such as the Journal of Politics, Journal of Conflict Resolution, Political Research Quarterly, Journal of Peace Research, International Interactions, Conflict Management and Peace Science, and Review of International Studies.
