I am an Assistant Professor in the Department of Mathematics and Statistics and an Affiliated Faculty in the School of Data Science at The University of North Carolina at Charlotte. My research interests include dimension reduction, functional data analysis, statistical machine learning, and graphical models. Prior to working at UNC Charlotte, I received a Ph.D. in Statistics at The Pennsylvania State University, B.S. in Statistics and B.S. in Mathematical Sciences at Seoul National University in South Korea.
