The oceanic area is where the oceanic plate forms at ridge, then grows, and subducts at trench. Unraveling structures under the oceanic area covering a vast area of the Earth surface is a key to know structure and evolution of the whole Earth. My research interest is to reveal interior structures, especially of electrical conductivity, and crustal and mantle dynamics at mid-ocean and back-arc spreading ridges, subduction zones, and others in the oceanic area, based on data obtained in sea-going experiments. In addition, to look at new sides of the Earth, I have worked on development of new data analysis methods.
Main Research Themes:
Revealing electrical conductivity structures of oceanic crust and mantle at mid-ocean and back-arc ridges and subduction zones from observational data.
Revealing Earth interior’s structure and Earth dynamics based on electrical conductivity structures.
Development of new methods of data analysis.
