About me
I am a PhD student under the supervision of Gye-Seon Lee at Seoul National University.
I am currently working on deformation spaces of properly convex real-projective structures on manifolds (or orbifolds), Coxeter groups, Vinberg's theory on projective reflection groups, and Hilbert geometry.
I am also interested in geometry and dynamics of discrete subgroups of Lie groups, higher (or higher-higher) Teichmüller theory, and geometric group theory. Especially, I recently started to look into extended geometric finiteness to study geometric finiteness of projective reflection groups.
