Inhyeok Choi / 최인혁 (He/Him)

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.
