By utilizing room temperature operable triplet DNP (Dynamic Nuclear Polarization), we dramatically amplify NMR and MRI signals through optically pumped spins. This enables the high-sensitivity detection of molecular structures and dynamics that have been difficult to observe conventionally. It is a next-generation spin polarization foundational technology that leads to the development of MRI molecular probes and applications in quantum sensing technology.

We study the structure and dynamics of functional materials using solid-state NMR, X-ray diffraction, and other spectroscopic techniques. We also develop and apply solid-state NMR techniques under gas atmospheres to analyze molecular behavior in porous materials. By combining multiple methods, we aim to reveal how structure and dynamics relate to material functions, contributing to the development of ion conductors, gas sorption materials, and molecular catalysts.
