My research field is theoretical study of chemical reaction mechanisms and materials properties based on approaches of theoretical chemistry and solid state physics.
In particular, I am interested in photo-chemistry, exciton/charge dynamics, and quantum transport, which play key roles in various systems including solar cells, photosynthesis , light-emitting materials, and organic electronics.
For efficient use of solar energy, I aim to clarify the energy conversion mechanisms from sunlight to electric and chemical energies, thereby providing design rules for preventing the energy loss and for increasing the energy conversion efficiency.
Besides, I theoreticaly study multi-exciton phenomena that originate in fascinating material functions, such as singlet fission that creates two electron-hole pair from one photon, as well as energy up-conversion due to triplet-triplet annihilation.
To this end, I apply electronic structure calculations, many-body quantum dynamics calculations, and various other methodologies in computational science.Further, I develop new theoretical/computational methodologies according to the purpose.
Since computational science can flexibly be applied for various phenomena, I also have motivation to step into unexplored research fields.
