About Me


I gained my Ph.D. in Mechanical Engineering from Tsinghua University in 2018.  After that, I became a postdoctoral research associate at the University of Oxford. In 2022, I joined the University of Twente as an assistant professor in the research group of Computational Design of Structural Materials.  

I specialize in the computational analysis of materials and structures, with particular focus on multi-scale materials and multi-physics problems. This has broad engineering applications ranging from the power generating industry to micromechanical materials.

My research focuses on understanding the behavior of complex, hierarchically structured materials through computational methods. This requires the combination of modeling techniques at different time and length scales. I work on developing multiscale and multiphysics computational methods, to advance the understanding of the microstructure-property-performance relationship of metallic materials, so as to investigate the degree to which microstructures are tunable to support the engineering of manufactured materials for temperature and radiation resistance.

My main research themes are:

  • Material defect physics and science (precipitates, vacancies/interstitials, dislocation loops, etc.)
  • Discrete dislocation plasticity
  • Coupled mechanical/diffusion modeling
  • Finite Element Modeling
  • Phase Field Modeling
