I am studying the structure of tectonic plates and its relation to tectonics, seismogenesis, magmatism and plate dynamics by using active and passive seismic data. My research area covers subduction zones and spreading centers worldwide. I have been working at JAMSTEC since 2014 and now am a researcher in Marine Seismology Research group, Subduction Dynamics Research Center, Research Institute for Marine Geodynamics of JAMSTEC.
