Another shot.
I am a mathematician at
KIAS
(Korea Institute for Advanced Study).
I received my PhD from
KAIST
under the supervision of
Harry Hyungryul Baik.
I am interested in various phenomena on groups with non-positive curvature.
What does it mean?
I think about some problems in group theory, low-dimensional topology,
dynamics, and probability theory. Examples include:
- interesting subgroups of some class of groups;
- statistics in hyperbolic surfaces, graphs, trees and CAT(0) cube complexes;
- random walks, escape rate and asymptotic entropy;
- percolation on Cayley graphs;
- limit sets and orbit distribution of Kleinian groups;
- Benjamini–Schramm convergence;
- bounded cohomology of hyperbolic and non-hyperbolic groups;
- interesting examples of groups.
There is a single keyword encompassing all of these: groups.
Hence I am deeply interested in groups.
Put more simply, I'm interested in objects and phenomena that exhibit rich symmetry.

AHM, a choice.
Whether or not one uses LLM, I invite people (and urge tenured people) to first think about how to preserve the maths community before writing one more paper. Worth read: various opinions in the agoda.
