Jaehan Park is an Assistant Professor at the S. Rajaratnam School of International Studies (RSIS) at Nanyang Technological University in Singapore and a Non-Resident Fellow with the Asia Program at the Foreign Policy Research Institute.

Park’s book project, The Geographical Pivot of Grand Strategy: Rising Powers in the Far East, 1895-1905, develops a theory of how states determine their geopolitical orientation focusing on path-dependent effects created by the interplay of geography, technology, and institutions. He received the Smith Richardson Foundation’s Strategy & Policy Fellowship for this project.

His broader research interests include international relations theory, East Asian security, and U.S. foreign policy. Park’s scholarly works have been published in Orbis, Texas National Security Review, and Palgrave Handbook of Contemporary Geopolitics. In addition, he has written for policy outlets, such as the Council on Foreign Relations, Survival, and War on the Rocks, and consulted with various organizations in both the U.S. and South Korea, including the Office of Net Assessment.

Previously, Park held fellowships at the Albritton Center for Grand Strategy at Texas A&M University, the Clements Center for National Security at the University of Texas at Austin, and the Notre Dame International Security Center, among others. He was also a David Rockefeller Fellow with the Trilateral Commission from 2020 to 2023.

Park received his Ph.D. (with distinction) and M.A., both in International Relations, from the Johns Hopkins SAIS and B.A. in Business Administration from Yonsei University in Seoul, Korea. Previously, he served in the Republic of Korea Army as an officer and worked in the financial sector.
