As a Researcher
I am interested in physics under strong gravity, described by general relativity. My research targets are from black-holes to the early Universe, particularly with its nonlinear natures which are studied by numerical simulations. Most of my works are related to "numerical relativity", including both actual simulations and fundamental formulations oriented to numerical applications.
