Research Interest: My research interest is collapsing of Rimannian manifolds. This research area is a part of Riemannian geometry and is to study a convergence called Gromov-Hausdorff convergence. Especially, I am studying a limit space of Riemannian manifolds whose Ricci curvatures have a definite lower bound.
