  • Short CV (Jan 2020)
  • Elder-rule-staircodes for augmented metric spaces  (with C.Chen, F. Mémoli, Y. Wang) has been accepted for publication in the Proceedings of  SoCG 2020, arXiv:2003.04523
  • Spatiotemporal Persistent Homology for Dynamic Metric Spaces has been published in Discrete & Computational Geometry, see Paper.

I am a 6th year Ph.D. student in Mathematics at the Ohio State Universitykim.5235.
I expect to graduate in
May 2020. I am working under the guidance of Facundo Mémoli. 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.

Prior to my time at Ohio State, I earned my Bachelor’s degree at Seoul National University in South Korea in 2014.
