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) and Institut d'Estudis Espacials de Catalunya (IEEC).
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 targets energetic phenomena ranging from the gas around supermassive black holes that power AGN to hot interstellar medium, galactic winds, and supernovae (and their remnants) in galaxies undergoing intense star formation, while the multi-wavelength surveys aim at understanding the formation and evolution of supermassive black holes across the cosmic history. For the latter, I am a core member of the SHELLQs (Subaru high-z exploration for low-luminosity quasars) project which focuses on quasars in the early Universe and involved in a few other international survey projects, including the Subaru PFS strategic survey program.
