Division of Science, National Astronomical Observatory of Japan

I am currently an assistant professor at Division of Science, National Astronomical Observatory of Japan. I also have a cross-appointment with the Astronomy Deparment of the Graduate University of Advanced Studies (GUAS/SOKENDAI).

My research field is astrochemistry in nearby galaxies. Astrochemistry is a study of abundances of various molecular species in its relationship with astrophysical properties. More than 260 chemical species has been found so far in the interstellar or circumstellar medium. Molecular gas that hosts this variety of species is the ingredients of star formation. This means that properties of molecular gas is related to current and future state of star formation. These properties of molecular gas can be dramatically different in galaxies with extreme activities. My research focus is these types of galaxies such as starbursts or active galactic nuclei, and mergers. With molecules, we can study how the molecular gas is affected by shocks, energetic photons (UV and X-rays), and cosmic rays.In particular, I am a Co-PI of an ALMA large program ALCHEMI, which studies the chemical compositions of a nearby starburst galaxy NGC 253.
