I earned my Ph.D. in Mathematics in May 2023, M.A. in Mathematics in May 2021, and M.S. in Computer Sciences in December 2020 at University of Wisconsin-Madison. I received my B.S. in Mathematics and B.A. in Economics from Seoul National University in February 2016. My research interests lie in machine learning theory and its application to real-world problems.
