1970.8 ~ 1978.8: technician of Harbin welding research institute of Dongan machinery factory.

1978.8 ~1980.1:graduate student majoring in mechanics at Harbin Institute of Technology.

1980.1~1984.9: He was sent to study in the UK and received a doctorate in applied mechanics from Manchester University.

1984.9 ~1991.1:Associate Professor, Department of Mechanics, Harbin Institute of Technology.

1991.1~1993.5: He was a senior visiting scholar at the University of California, Santa Barbara, and was later hired as an associate researcher by case western reserve university, mainly engaged in the research of electromechanical coupling effect of artificial intelligence materials.

1993.5 ~ At present: Professor, Doctoral Supervisor, Department of Aerospace Engineering and Mechanics, Harbin Institute of Technology, Deputy Director of Editorial Board, Editor-in-Chief of Journal (English Edition). The main research results include the analytical solution of electromechanical coupling of piezoelectric sensing devices, the singular solution of boundary element equation of piezoelectric materials, the finite element algorithm of nonlinear iron polarized materials and the micro-mechanism of material size effect. He has published more than 50 papers in academic journals and international conferences at home and abroad. Some theoretical achievements have been used in the development and production of microelectronic devices.

In 2002, he was awarded an excellent teacher of mechanics by theoretical and applied mechanics Institution in China. Discipline: solid mechanics

Mainly engaged in computational mechanics, composite micro-fracture mechanics, molecular dynamics, computer molecular simulation and molecular design research topics. Based on the first principle of matter, molecular dynamics and Monte Carlo method, the physical, chemical and mechanical behaviors of materials, such as dislocation and crystal deformation (crystal plasticity), lattice defects and fracture evolution, thin film and epitaxial growth, diffusion and phase transition, polymer conformation and polymer configuration, are simulated by computer parallel algorithm. Research on the theory and calculation method of multi-time level across matter from atomic scale. This research field belongs to a new interdisciplinary subject, which has broad application prospects in the fields of new materials, nanotechnology, hypervelocity collision, micro-electromechanical devices, biology and informatics.
