Research Interests:

　Based on geologic and numerical approach, we have been studying about “secrets of the earth” (life and environmental evolution, tectonics, earthquake and volcanic eruption in plate subduction zone, etc.). Our approaches are composed mainly of relevant three topics:

1) Subduction zone dynamics and tectonics:
Plate subduction is a unique phenomenon of the earth, which apparently contribute to keep our planet earth habitable. By means of onland geology and ocean drilling (e.g. IODP), we are focusing on earthquakes, submarine landslides, tectonics, and the other geologic phenomena in plate subduction zones.

2) Collaborative study: Geology/Engneering:
Collaborative study between Geology and Engneering is useful to examine a role of physical properties of sediments in geologic phenomena. Laboratory experiments (e.g. Consolidation test, permeability, rock mechanics, etc.) are also conducted to examine the geologic hypothesis constructed in 1)

3) Mathematical research:
We consider paleobiology and structural geology from a viewpoint of mathematics.

Major research topics:　

• Geothermal structure and physical props variation in accretionary complex
• Spatial distribution of mass-transport deposits
• Experimental study on dynamic-consolidation associated with earthquake
• K/Pg extinction event in terms of evolution of detritus food chain
• Multi-fractal analyses of aurora morphology
