Matching Theory · Market Design · Dynamic Matching

I am a Postdoctoral Researcher at the Center for Economic Research, Shandong University. I received my Ph.D. in Economics from the Shanghai University of Finance and Economics in 2025.

My research interests include matching theory, market design, game theory, and mechanism design, with a particular focus on dynamic and multi-period matching. I study how stability, commitment, strategic behavior, and institutional constraints shape matching outcomes over time.

My research has been published in Economics Letters and the Journal of Mathematical Economics. My current work examines the implementation and non-cooperative foundations of dynamic matching rules, the role of commitment and legal enforcement in dynamic matching markets, and positional preferences in school choice.
