I am a historian of political thought working at the intersection between intellectual history and International Relations. My research centres on the ideas of empire and international order in early twentieth-century Britain, the United States and Japan. I also examine as my additional work the postcolonial/decolonial thought in the Pacific Islands. 

I am the author of The International Thought of Alfred Zimmern: Classicism, Zionism and the Shadow of Commonwealth (Palgrave Macmillan, 2021), which was a revision of my PhD dissertation submitted to the University of Cambridge in 2016. It is an in-depth analysis into the development of the imperial and international thought of the world's first professor of IR. My other publications include "Colonial Policy Studies in Japan: Racial Visions of Nan'yo, or the Early Creation of a Global South," a contribution to International Affairs 100th anniversary issue ‘Race and Imperialism in International Relations' (Vol 98, No 1, 2022).

Since April 2018 I have been based in the University of Tokyo, Komaba, Japan, where I am an Associate Professor of the History of Political and Social Thought. I was previously an Assistant Professor at Waseda University, Japan (2016–18).

I currently serve as a Trustee of Toynbee Prize Foundation.


Ph.D. (University of Cambridge), MA (University of Tokyo), BA (University of Tokyo)

I studied international relations and the history of political thought at the University of Tokyo, Komaba; and British intellectual history with a focus on empire and international relations at the University of Cambridge, where I was based at the POLIS Department and Christ's College.


I am a recipient of JSPS Prize (2022) from Japan Society for the Promotion of Science, and Mizuta Prize (2021) from Nagoya University.
