Born and educated in Japan. After obtaining PhD in astrophysics at Nagoya University, Nagoya, Japan, in 1995, I moved to Europe, working at the Institute of Astronomy, Cambridge in UK (1995-2005), at the Max Planck Institut für Extraterrestrische Physik in Germany (2005-2008), and at INAF-Osservatorio Astronomico di Bologna in Italy (2008-2009). In 2010, I joined ICREA, to work as an ICREA Research Professor at the Institut de Ciències del Cosmos of Universitat de Barcelona (ICCUB).
Research interests
My research is an observational study of star-forming galaxies and supermassive black holes that power active galactic nuclei (AGN), mainly at X-ray wavelengths as well as at other wavelengths in cosmic survey projects. The X-ray study is aimed to understand the physics in high-energy phenomena observed in galaxies undergoing intense star formation and the vicinity of central black holes in AGN. The multi-wavelength survey projects aim at understanding the formation and evolution of supermassive black holes. Presently, I am an active member of the multiwavelength projects of GOALS (Great Observatories All-sky LIRGs Survey) for local luminous infrared galaxies, SHELLQs (Subaru High-z Exploration for Low-Luminosity Quasars) for the most distant quasars, and eROSITA-Subaru/HSC collaborations for new X-ray selected AGN.
