【Submarine geophysics &
tectonics】
My main scientific interest is the mid-ocean ridge process, how the plate kinematics, mantle upwelling and melting variations result in a large differences in the world ridge system. I study the tectonics of mid-ocean ridges and backar basin spreading process using morphology, magnetic anomaly, gravity and sonar images of the seafloor.

【Marine geology】
Fluids in subduction zones play important roles on deformation, thermal structure and material cycle. In order to know relationships between behavior of fluid/gas and growth of an accretionary prism, I am studying subsurface or surface expressions of fluid/gas migration, such as methane hydrate, cold seep, and mud volcano in the Nankai Trough. Moreover, I attempt to reveal distribution and displacement history of active faults associated with great earthquakes along the Nankai Trough.

【Marine geology and geophysics】
My scientific interest is comprehensive understanding on trench-arc-backarc basin systems on Earth. I focus on marine geologic and geophysical studies in the plate convergent margin such as Nankai Trough, mainly through 2-D and 3-D multichannel seismic (MCS) reflection investigations. I am currently doing 2-D and 3-D prestack depth imaging studies and physical property estimation along the Nankai subduction zone.

Radiolarians are a siliceous microorganism inhabiting the shallow to deep-water depths of the world Ocean and their fossil have the potential to be a powerful paleoenvironmental proxy providing us ecological information about the water masses from sallow to deep water depth. One of my research consists in clarifying modern radiolarian species ecology by analyzing modern samples such plankton tows, surface sediments and sediment trap for try to understand their species spatio-temporal distribution. My second research objective is to use the knowledge obtained from modern studies to estimate the response of marine fauna to the earth climate changes during the Cenozoic analyzing deep-sea core sediments. When trying to reconstruct paleoenvironment of old time period, we have to consider the ecology of extinct species, which are unknown and thus hamper the reconstructions. My third objective is to try to solve this issue clarifying extinct species paleoecology for allow more accurate paleoceanographic reconstructions. ・Hydrothermal activity beneath the ocean floor
