Expectations for WRHI

Europe-Japan international collaborations were promoted by JSPS Core-to-Core Program (Japan-Germany-France-UK International Collaboration). I hope that WRHI will support this international collaborations and make the research links stronger. WRHI will be able to promote the international collaboration with US researchers. By these international collaborations, I would like to contribute to establish World Research Hub in TokyoTech.

Research Projects

  • Electron-Proton Decoupling in Excited State Hydrogen Transfer

  • Ionization Induced Site Switching Dynamics Studied by Picosecond Time-Resolved Spectroscopy

  • Spectroscopy of Adrenaline Receptor Pocket by ESI / Cold Ion Trap Laser Spectroscopy

  • Development of Focused Ion Beam / Laser Ionization Mass-Spectrometer and Application to Transboundary Air Pollution

  • Solvent migration dynamics in clusters

    Solute-solvent interactions are fundamental for chemistry and biology as these interactions strongly affect solution dynamics. A clear-cut interpretation is difficult in solution due to surrounding but spectating molecules. Our international collaborations has been providing clear mechanism of solvent migration dynamics based on unique combination of picosecond time-resolved three color IR spectroscopy (Fujii), and electron-impact IR photodissociation spectroscopy (Dopfer). Solovation dynamics at molecular level will be established and will give impact on solution chemistry, biology and related research field.
