Outline Activities
Research on the dynamics and rheological structure of the Earth using sea-level changes, gravity anomaly and crustal movement. In particular, I have beeen studying glacial rebound, Earth's several rotations, mantle viscosity, core-mantle coupling, mantle convection and coupling between the crust and upper mantle beneath the island arcs.
