Research Interests

  • Computational material science
  • Radiation effects in materials
  • Defect engineering
  • Energy storage applications
Dr. Zhao's research interests are computational materials science, in particular, influence of defects on materials properties. Both intrinsic defects and defects produced by ion beams are considered. For this purpose, various computational methods, spanning from density functional theory, molecular dynamics and kinetic Monte Carlo simulations are employed.

The group is actively seeking for PhD candidates with background in computational material science, computer science, and engineering. Currently we are looking for highly motivated Ph.D. candidates and undergraduate research assistants to join us, especially those who has a programing background.
