Research Topics

Plasma kinetic simulations with Multi-Moment Advection scheme
The kinematics of space plasma is fully described by the first principle Vlasov-Maxwell equations. We develop an advanced technology, called Multi-Moment Advection scheme, to numerically solve the Vlasov equation (collisionless Boltzmann equation) with unprecedented high accuracy, and apply it to non-linear plasma kinetic simulations such as collisionless shock and magnetic reconnection.

Numerical simulations of Magneto-Hydro-Dynamic instabilities
Using high-order Magneto-Hydro-Dynamic (MHD) simulation code, we study macro-scale phenomena in space plasmas such as the kelvin-Helmholtz instability, Magneto-Rotational Instability, and magnetic reconnection.
