I'm an Assistant Professor in Department of Statistics, College of Economics, Sungkyunkwan University (SKKU).
During 2017-2020, I worked as a Research Associate in Department of Biostatistics, Harvard T. H. Chan School of Public Health, mentored by Francesca Dominici. I received my Ph. D. at the University of Pennsylvania in 2017 under the supervision of Dylan S. Small. My primary interest is developing statistical methods for causal inference.

Broadly speaking, I'm interested in developing statistical methods for causal inference. More specifically, I focus on developing nonparametric methods for instrumental variable models and discovering effect modification in observational studies. I'm also interested in applying the methods I developed to areas such as epidemiology, public health and medicine to answer practical real-world questions.
