The group focus on following three fundamental research objectives:
- establishment of the mineralogical model of the Earth's whole mantle (upper mantle, transition zone, and lower mantle)
- clarification of the differentiation process of the early Earth from fully molten state
- exploring the internal structure of giant planets such as super-Earth, ice giants, and gas giants
Ultimately, by combining all the knowledge from those research outcomes, the group wants to propose the universal internal evolution model of the planets.
