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_June_2022.
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.
I am interested in persistence theory in topological data analysis (TDA) and their applications. 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 TDA. I also often run into computational geometry & topology questions during my research.
