Research Field

  • Extragalactic astronomy, optical and near-infrared astronomy, instrument development

Brief Introduction of Research

  • Based on observations using Subaru Telescope and other facilities, we are trying to understand how galaxies have formed and evloved across the cosmic time. In order to explore the most distant (i.e., the earliest) galaxy populations, we need to make sensitive observations in infrared wavelengths. I am also invlolved with the development of a very wide-field and sensitive space telescope.
