I’m a William W. Elliott Assistant Research Professor of Math at Duke University (2020 – 2023). My mentor at Duke is Ezra Miller. My short CV is here: CV_07/13/21.

I am interested in the theoretical foundations for persistence theory in topological data analysis and their applications to dynamical systems. For my research, I primarily exploit concepts from algebraic & combinatorial topology, (algebraic) combinatorics, metric geometry, commutative algebra, representation theory, and category theory, blending these with ideas of *persistence* in topological data analysis. I also often run into computational geometry & topology questions during my research.

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.
