I'm a historian with a strong interest in International Relations (IR). My main research area is twentieth-century international thought, with a focus on the United States and women as international thinkers. I have co-edited, with Patricia Owens, Women's International Thought: A New History (Cambridge University Press, 2021) which won the 2021 Joseph Fletcher Prize as well as the 2021 Prize for Best Edited Volume from the Theory Section of the International Studies Association (ISA). With Owens, Kimberly Hutchings and Sarah C. Dunstan, I also edited Women's International Thought: Towards a New Canon (Cambridge University Press, 2022), which won the British International Studies Association (BISA) 2023 Susan Strange Prize for the Best Book in International Studies; the ISA Theory Section Prize for Best Edited Volume; and an Honourable Mention from the ISA Feminist and Gender Studies Best Book Prize. My article "U.S. Foreign Policy Think Tanks and Women’s Intellectual Labor, 1920–1950” won the 2023 Arthur Miller Institute Article Prize from the British Association for American Studies (BAAS), and an Honorable Mention from the Historians of the Twentieth Century United States (HOTCUS).

My other publications have examined the history of foundation philanthropy and U.S. foreign policy, philanthropic support for IR as a discipline, the international and transnational history of international law, and the history of publics and counterpublics. I was a Fellow-in-Residence at the University of Oxford's Rothermere American Institute (autumn 2020) and a Visiting Senior Fellow at the LSE Department of International Relations (autumn 2025). I have been a Fellow of the Royal Historical Society since 2021.

I have communicated my research on BBC radio, several podcasts in the US and the UK, and in the press. I have helped non-academic organizations better understand their own history, for instance the United Nations Library in Geneva and the foreign affairs think tank Chatham House.

Before coming to Sussex, I was the Mellon Research Fellow in American History at the University of Cambridge and a Bye-Fellow of Pembroke College, Cambridge. My research has been supported by the British Academy, the Leverhulme Trust, the German Academic Exchange Service, the Iowa Women's Archives, the Rockefeller Archive Center, the Gilder Lehrman Institute of American History, the Roosevelt Study Center, the Oslo Contemporary International History Network and the Society for Historians of American Foreign Relations. Most recently, I have held a Leverhulme Research Fellowship (2025-2026). 

At Sussex, I have served as Subject Head for American Studies and founding director of the relaunched Sussex Centre for American Studies (2021-2024), as well as a member of the Faculty of Media, Arts and Humanities' Research Committee (2021-2024) and the University-wide Religion and Belief Forum (2022-2026). Externally, I have served on the membership, programme and book prize committees of the Society for Historians of American Foreign Relations. Since 2023, I have been Vice Chair of HOTCUS (Historians of the Twentieth-Century United States).
