Tokyo 1991, Prof. of Univ.Tokyo 1999, Prof. of Graduate School of Frontier Science, Univ.Tokyo Educational Activities Complexity Earth Sciences in GSFS, University of Tokyo Rheology of Earth Materials, Faculty of Science, University of Tokyo Research Activities (1) Metamorphism of plate boundaries , P-T paths estimation by the thermodynamic inversion method for garnet and amphiboles, dehydration and hydration paths by inversion method for garnet and amphiboles, mechanical coupling of slab and arc crust by means of crack geometry and genesis, hydration and dehydration coupled with mechanical behavior of plate boundary. (2) Rheology of earth materials, preferred orientation dynamics of mantle rocks, sintering processes in the upper mantle by shape transformation during annealing in mantle, dislocation dynamics in olivine, growth kinetics of mantle minerals. (3) Non-linear dynamical systems in geological processes, metasomatism of metamorphic rocks in the plate boundary, grain coagulation and growth in the shear flow regime, sedimentary structure formation in the plate boundary. Literature See http://www.gaea.k.u-tokyo.ac.jp Other Activities Future Plan Messages to Students My goals for the research activities in our laboratory are focused on obtaining fundamental models of geological processes in the mantle and crustal domains, in particular, for plate boundaries . Students in this field should have a strong undergraduate background in physics, mathematics, chemistry, and geology
