Research Themes:

  • Development of high-pressure high-temperature generation techniques and application to planetary interiors
  • Development of synthesis technique for large single crystals of the Earth’s mantle
  • Determination of physical properties (elasticity, plasticity and transport properties) of minerals under high-pressure and -temperature
  • Local structures of minerals and magmas (glasses) by spectroscopic techniques (NMR, Raman, IR, etc.)
  • Crystal structure determination of new high-pressure phases by diffraction techniques
  • Solution mechanisms for volatile species in magmatic melts and nominally anhydrous minerals
  • In-situ observation and analysis of synthetic samples under conditions of planetary surface and interior
