Research Interests

Computational condensed matter physics, particularly on high-pressure physics, where the state of art ab-initio molecular dynamics simulation method provides an access to an extreme condition, i.e., high pressure and temperature, to investigate the phase diagram of materials. Quantum effect in the light element materials, like solid hydrogen, is also of great interest.
