I studied history and American studies at the University of Birmingham, gaining my PhD in 2003. During this time I was also a Research Associate at the Centre for Studies in Security and Diplomacy at Birmingham. From 2003 I was a lecturer in International Politics at Aberystwyth University, leaving in 2013 to join the University of Essex. I have also been a Visiting Researcher at Georgetown University in Washington DC and an Eccles Fellow in North American Studies at the British Library.
I am currently writing a book on the United States and the European empires of the late nineteenth century. This is an attempt to explain how American elites, especially Republicans who dominated policymaking after the Civil War, understood and reacted to empires and imperialism, and how these views affected their ideas about the role of the United States in the international system.
