Susan Colbourn focuses on contemporary international history, particularly transatlantic relations, the Cold War, and nuclear history. Her current project, entitled Euromissiles: A Transatlantic History, examines the rise and fall of the intermediate-range nuclear force arms race and its impact on the Atlantic Alliance, considering the intersections between East-West and West-West relations and the impact of public opinion and social activism. She is also interested in methodological questions about how declassification and digitization efforts can be used in the study and teaching of international, transnational, and global histories.
She is also interested in histories of Canada and the world and co-edits a blog on Canadian international history, Canadian Eyes Only.
