We focus on determining the seismic structure of Earth's deep interior to understand its chemical composition and dynamic processes. We have applied and developed many techniques to map the fine seismic structures at various depths. A variety of research projects including the inner core hemisphericity and anisotropy, fine seismic structure near the core-mantle boundary, seismic reflectors in the mid-mantle depths, lateral variation of the mantle transition zone structure, the crust-mantle transition and depth distribution of seismic anisotropy is ongoing in our group.
