The research direction is amorphous physics and computational physics, and the current research work mainly focuses on the following four aspects: (1) the structure and dynamics theory and simulation of amorphous systems; (2) Abnormal crystallization behavior in extreme environment; (3) Development and application of high-throughput molecular simulation methods; (4) Computer simulation of physical and chemical properties of high-density energetic materials.

The main research achievements include: (1) systematic and in-depth study on the relaxation kinetics of amorphous transition, vibration dynamics and aging dynamics of amorphous alloys. The origin, development and evolution of the secondary relaxation process were revealed, and a kinetic quantization mechanism was proposed to explain the aging behavior of amorphous alloys. (2) The crystallization process of nano-scale tetrahedral droplet and liquid film reveals the mechanism of free surface influence on crystallization process. Research work at Phys. Rev. Lett., Phys. Rev. B/E, Acta Mater., J. Chem. Phys., Phys. Chem. Chem. Phys. He has published more than 50 academic papers in academic journals at home and abroad. He has presided over and is undertaking three National Natural Science Foundation youth and surface projects, participated in one National Natural Science Foundation key fund and one national defense key project, and won one provincial and ministerial science and technology first prize.
