Welcome! I am a Ph.D. Candidate in Political Science at the University of California, Berkeley, with a Designated Emphasis on Political Economy through the Berkeley Economy & Society Initiative, and a Data Science & AI Fellow at the Data Science Lab. In the dissertation, I study an extreme version of economic de-globalization: the rising trend of advanced democracies leveraging national security to restrict multinational enterprises from both emerging and established markets. First, I unpack why, when, and how political elites in host markets do so in Congress and on social media. Second, I examine the downstream reactions to this disruptive shift among societal groups (e.g., consumers and private firms) and how their responses shape the cross-border diffusion of cutting-edge technologies. I use original and commercial data, survey experiments, field experiments, and elite interviews to explore these questions.
My dissertation, titled Championing Economic National Security in a De-Globalized Era, won the 2025 Best Doctoral Dissertation Proposal from Academy of International Business. My other projects focus on political risk, industrial policy, and corporate non-market strategy (e.g., information). I am grateful for funding support from Berkeley Economy & Society Initiative, Citrin Center for Public Opinion Research, Helsinki Geoeconomics Society, and Institute for Humane Studies.
Prior to doctoral studies, I worked at the American Enterprise Institute, the Center for Strategic and International Studies, and the Institute of New Structural Economics at Peking University. I received an M.A. in International Economics and International Relations from Paul H. Nitze School of Advanced International Studies, Johns Hopkins University. I earned a B.Soc.Sci. in Government and International Relations from Hong Kong Baptist University, where I was awarded a national scholarship (top 0.05%) and graduated top of my cohort.
