I am an Assistant Professor of Political Science and an affiliate of the Environment, Energy, Sustainability, and Health Institute at Johns Hopkins University. I have interests in the history and theory of international order, global environmental politics, science and politics, and qualitative methods. All my work places international policy in a long-term historical perspective so that we can understand how and why we came to solve problems in particular ways. On the theoretical side, I have been working to develop new theories of change that are better able to account for the dynamism, complexity, and contingency of international politics. 

My first book, Scientific Cosmology and International Orders has just been published in the Cambridge Studies in International Relations series at Cambridge University Press. This book shows how scientific ideas have transformed international politics over five centuries. In doing so, it traces the history of economic growth as a central purpose of states. 

Two papers from my second book project on the history of climate governance have been published in International Organization and International Studies Quarterly. This project seeks to explain the form and content of global climate policy by examining the dynamic interaction of scientific knowledge and geopolitics during the Cold War. I have a new article out at the European Journal of International Relations that tries to situate the theoretical framework for the project in the history of IR.

 I have also been working with Ted Hopf (National University of Singapore) and Srdjan Vucetic (University of Ottawa) to build a national identity database and relate the findings to the history and theory of international order. The first results from the project have been published in Making Identity Count: Building a National Identity Database (Oxford University Press, 2016). Our first paper relating the findings to hegemonic transition theory is available at International Organization
