I’m a William W. Elliott Assistant Research Professor of Math at Duke University (Aug 2020 – July 2023): Short_CV_Aug/05/2020. My mentor is Ezra Miller.

I am interested in the theoretical foundations for persistence theory in topological data analysis and their applications to dynamical systems. Also, I am interested in metric geometry.

I received a Math Ph.D. in May, 2020 from Ohio State. I was working under the guidance of Facundo Mémoli . Before that, I earned my Bachelor’s degree at Seoul National Univ. in South Korea.
