I am a historian of war and diplomacy in the ninteteenth and twentieth centuries. My current research focuses on the relationship between sea power and world order in British and American strategic thought during the first half of the twentieth century, and during 2023 I held a Kluge Fellowship at the Library of Congress to start work on my next book project, which examines these themes in the decades following the First World War.
I joined the University of Plymouth in 2019 from Merton College, Oxford, where I completed my DPhil thesis titled 'Internationalising Sea Power: Ideas of World Order and the Maintenance of Peace, 1890-1919'. At Merton, I held the John Roberts MC3 (Great War) scholarship between 2015-18, and a Smith Richardson Foundation Predoctoral Fellowship at International Security Studies, Yale University, between 2018-19. I previously completed my BA in War Studies at King's College London, and my MA in History at the University of Calgary.

Other research

During 2023, I held a Kluge Fellowship at the Library of Congress, where I began work on my next project, titled 'Sea Power, Identity, and the Creation of the 'Liberal International Order', 1920-1950'. I am also currently completing a book project which builds on my DPhil thesis, completed at the University of Oxford, examining the role of sea power and international naval co-operation in visions of world order between 1890 and 1919, culminating in the creation of the League of Nations. Elements of this work have recently been published in the article ''Peace throughout the oceans and seas of the world': British maritime strategic thought and world order, 1892-1919', which won the 2020 Sir Julian Corbett Prize in Modern Naval History. I have previously published on other aspects of the First World War, including an article on intelligence assessments of the success of attrition on the Western Front between 1914 and 1917. I have also co-edited a collection on time and the First World War, and a volume on economic warfare, grand strategy, and sea power between 1650-1945.
