Research

I am a seismologist working on seismic tomography and attenuation to image the inner structure of Earth better. I am particularly interested in understanding mantle dynamics while accommodating observations of seismic anisotropy in different geological settings. My research area has been expanded from the relic and active subduction zones to the intraplate and hotspots.

Research

My research focuses on understanding the geodynamical processes in subduction systems such as melt transport and the development of back-arc basins. A simple 2-dimensional numerical subduction model I developed shows that the arc location can be explained by the thermally-controlled melt focusing mechanism. I am also interested in understanding the opening of a back-arc and the thermal influence of a back-arc spreading center on the arc location. Subduction zone geodynamical modeling can give us an important clue to understanding the interaction between the deep mantle and surface process.

Post Doctoral Scholar in Volcanology and Petrology 

PhD, Jan 2022, Seoul National University

Research

I study geologic processes in various alkalic magma systems using hard-rock geochemical tools. Currently I have a particular interest in Cenozoic alkalic magmatism around northern Victoria Land, Antarctica, where a complex spatio-temporal evolution of distributed volcanism can be traced. The combination of geochronological and petrogeochemical data achieved from here provides invaluable information concerning magma dynamics, elemental cycling, and implications on palaeoenvironments and volcanic hazards.
