I am an Assistant Professor in the Department of Statistics at Ewha Womans University. Before joining Ewha, I was an Assistant Professor in the Department of Mathematics and Statistics at Wake Forest University. I got my Ph.D. in Statistics from The Pennsylvania State University under the supervision of Dr. Bing Li and B.S. in Mathematics at Sogang University, Seoul, South Korea. My research interests include: Sufficient Dimension Reduction, Graphical Models, Functional Data Analysis, Causal Inference, Machine Learning, and Deep Learning.
