I am a Professor of European History at the School of European Languages, Culture and Society of University College London (UCL) and, since 2010, an Associate Director of the UCL Centre for Digital Humanities. My research interests encompass various aspects of contemporary history, with a current focus on the history of early twentieth-century internationalism and on digital approaches to historical inquiry. I am a seminar convenor at the Institute for Historical Research (IHR), part of the University of London’s School of Advanced Study (SAS), and a co-founder of the Richard Deswarte Prize for Digital History. Recent publications include Pieter Geyl and Britain: Encounters, Controversies, Impact (University of London Press, 2022; co-edited with Stijn van Rossem) and: The European Unity League: Sir Max Waechter and the idea of Europe, 1904–1924 (London: Bloomsbury, 2025, forthcoming).
