About Me


I am a final year Ph.D. Candidate in the Department of Statistics at the University of Wisconsin–Madison, advised by Prof. Zhengjun Zhang. In Summer 2020, I interned at Zillow Offers Machine Learning Team as an applied scientist. Prior to coming to Madison, I was a visiting research intern in Statistical Computing Lab at Seoul National University. Before that I was a software developer at SAP Labs Korea. I completed my M.A. in Statistics at Columbia University, and B.S. in Electrical Engineering and B.A. in Economics at Seoul National University.

Research Interests

My research interests lie in time series and their dependence modeling, with applications to risk management and predictive analytics. Specifically, I develop statistical models for a multivariate time series that possesses heavy tails and various dependence structures, leveraging extreme value theory and econometric techniques. I am also interested in combining machine learning algorithms and classical time series methods to improve forecasting accuracy.
