Mayumi Fukushima is a Stanton nuclear security postdoctoral fellow at the RAND Corporation. Her research interests include international security issues in East Asia, international security alliances, and nuclear nonproliferation. She has been trained in security studies, international relations, and international political economy.
Prior to RAND and MIT's Ph.D. program, she had a long experience of serving as a fast-track career diplomat (deputy director) at the Japanese Ministry of Foreign Affairs primarily responsible for U.S.-Japan cooperation to address various security challenges in Asia and beyond. She was also a Smith Richardson Foundation predoctoral fellow at Yale University's International Security Studies Program in 2018-19 and a visiting scholar at the Japan Maritime Self-Defense Force Command and Staff College in 2016-17.
Her academic research has been supported by various organizations including MIT's Center for International Studies and Political Science Department, the Stanton Foundation, the Smith Richardson Foundation, Yale University’s International Security Studies Program, the Murata Science Foundation, and the Ito Foundation for International Education Exchange.
Fukushima earned a Ph.D. in political science from Massachusetts Institute of Technology (MIT) in September 2020. Her Ph.D. dissertation, "Exploitative Friendships: Manipulating Asymmetric Alliances," explains the origin of different strategies junior allies employ to "manipulate" their materially superior security partner into offering assistance they seek. It contributes to the literature by proposing a new paradigm for understanding alliance behavior and assessing costs associated with offering security commitments to other states.
