Patrick O. Cohrs is Associate Professor of History and International Relations at Yale University. Professor Cohrs received his doctorate from the University of Oxford in 2002. He has held fellowships at the Center for European Studies and the Kennedy School's Belfer Center for Science and International Affairs at Harvard University. Before moving to Yale, he was the Alistair Horne Fellow at St Antony's College, Oxford, and taught at Humboldt University Berlin. Professor Cohrs is currently working on a history of the Pax Americana which reappraises American aspirations for a 'new world order' from their origins to the Cold War and explores how far they contributed to the creation of a more legitimate international system. He teaches courses in modern international history, particularly on the United States and the world, the history of global, transatlantic and European international politics, and classic and new approaches to international history. He is one of the co-founders of the Yale International History programme.
