Greetings! I am a Postdoctoral Research Associate in the Department of Operations Research & Financial Engineering (ORFE) at Princeton University, where I have the privilege of being advised by Prof. Jianqing Fan. Prior to joining Princeton, I earned a Ph.D. in Economics from Rutgers University, where I was fortunate to be advised by Prof. Yuan Liao. I will be on the 2025–2026 job market.
My research interests lie in high-dimensional models, factor analysis, causal inference, human preference learning, and machine learning. I am also interested in fundamental economic allocation problems, such as matching applications. In particular, my current work focuses on estimation and uncertainty quantification in (heterogeneous) human preference learning and exploring their applications.
