Research Interests

My research field is galaxy formation.
I’m using super computers to study galaxy formation and I have great interest in the origin of the morphological variation, such as spiral and elliptical galaxies.
Pricious numerical simulations will reveal the formation process of galaxies and the origin of the galactic morphology.
Additionally, it allows us to study the environmental change of the stellar systems, such as solar system, which would be important for the evolution of life on planets.
Recently, I have been developing new numerical techniques to study the moon formation and the long time evolution of solid planets.
