My research interests lie in observational cosmology and cosmological galaxy formation. I have developed a phenomenological model of cosmological galaxy formation in order to gain insights into the physics of galaxy formation through observation.

I am also interested in the accelerated expansion of the universe. In the Kavli IPMU, I will tackle this greatest mystery in the Universe by using the theoretical galaxy formation model and various observational data sets, including the 3D galaxy map which will be obtained by the Subaru PFS.
