My main research area is the theory of mean dimension. Mean dimension is a topological invariant of dynamical systems introduced by Gromov in 1999.

While his motivation is to propose a new approach to infinite dimensional dynamical systems in geometric analysis, Elon Lindenstrauss and Benjamin Weiss found several applications of mean dimension to topological dynamics. I have studied both geometric analysis approach and topological dynamics approach to mean dimension theory. More concretely I have been studying the following three themes.(1) Dynamical systems of holomorphic maps from the complex plane ([1,3]).

(2) Dynamical systems in 4-dimensional gauge theory ([2]).

(3) Problem of embedding a dynamical system into the shift on the Hilbert cube ([4]).Main papers:
