Outline Activities
My group studies dynamics of Earth and planetary interiors based on experimental mineral physics at high pressure. We have several high-pressure deformation appratuses, including a deformation Kawai (D-111) type apparatus, a deformation-DIA (D-DIA) apparatus and diamond cells. We also conduct high-pressure in-situ X-ray studies at synchrotron facilities of SPring-8 and Photon Factory. By using these techniques, we study "deep rock dynamics" such as transformation kinetics, rheology, and their interactions in deep Earth materials and planetary ices. Recent and current research topics include metastable transformations and deep earthquakes, weakening of the lower-mantle slabs, internal dynamics of icy bodies, and non-equilibrium reactions in shocked meteorites and diamond inclusions.
