I was born in 1972 in Nagoya city, and grew up in Komaki city until I moved to Kyoto city in 1991 to enter Kyoto University. I am a graduate of the Molecular Chemical Physics laboratory (The former Terao Group, which is now Takegoshi group) in Division of Chemistry, Graduate School of Science, where I studied on solid-state nuclear magnetic resonance (NMR), such as

  • Dipolar recoupling experiments under Magic Angle Spinning (MAS), and
  • Dynamic Nuclear Polarization (DNP) using photo-excited triplet electron spins.

Until 2007 Aug, I had been a staff member at the Kitagawa lab in Osaka University.

My main research interest is in
  (i) fundamental studies,
  (ii) engineering and technical development, and
  (iii) novel applications
of nuclear magnetic resonance (NMR) spectroscopy.
