**News. ** (Jan 6th, 2021) A new paper “Interleaving by parts for persistence in a poset (with Memoli and Stefanou)” has been posted on arXiv.

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

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.
