Chong Ja Ian is an Associate Professor of political science at the National University of Singapore. He received his Ph.D. from Princeton University in 2008 and previously taught at the Hong Kong University of Science and Technology. His research covers the intersection of international and domestic politics, with a focus on the externalities of major power competition, nationalism, regional order and security, contentious politics, and state formation. He works on US-China relations, security and order in Northeast and Southeast Asia, cross-strait relations, and Taiwan politics. Chong is author of External Intervention and the Politics of State Formation: China, Indonesia, Thailand, 1893-1952 (Cambridge, 2012), a recipient of the 2013 International Security Studies Section Book Award from the International Studies Association. His publications appear in the China Quarterly, European Journal of International Relations, International Security, Security Studies, and other journals. At the Harvard-Yenching Institute, Chong will examine how non-leading state behavior collectively intensifies major power rivalries, paying particular attention to the US-China relationship. He has concurrent projects investigating how states react to sanctions on third parties by trade partners and the characteristics of foreign influence operations.
