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.
