I am an Assistant Professor of Statistics at Sookmyung Women's University and an Adjunct Professor of Quantitative Applied Economics at Sungkyunkwan University.
Before joining SMU, I served as a Senior Economist in the Office of Economic Modeling and Policy Analysis at the Bank of Korea for 14 years.
I completed my Ph.D. in Statistics at Pennsylvania State University, focusing on interpretable statistical learning, advised by Dr. Jia Li, and hold a B.A. in Economics and Statistics from Korea University.
My research interests span a range of topics, including:
