Greetings! I am an Assistant Professor in the School of Economics at the University of Seoul. Prior to joining the University of Seoul, I earned my Ph.D. in Economics from Rutgers University under the supervision of Prof. Yuan Liao. I then worked as a Postdoctoral Research Associate in the Department of Operations Research and Financial Engineering (ORFE) at Princeton University, where I had the privilege of working with Prof. Jianqing Fan. 

My research interests lie in high-dimensional models, spectral methods, 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 their applications.
