Brief Introduction of Research

  • Star formation history of the Universe tells us that galaxy formation and evolution peaked about 10 billion years ago or redshift of 2. I am interested in this particular cosmic epoch to understand the formation and evolution of galaxies by investigating the star formation rates, metal contents, and stellar populations. To carry out the research, I use large optical and infrared telescopes such as Subaru Telescope and Keck Telescope. Recently, I am also working on nearby disk galaxies observed by a state- of-the-art integral field spectrograph on VLT to understand physics taking place in a 100 pc scale of galactic disks and bulges.
