--Short Bio--

Yun-Jiang Wang is currently a full professor at Institute of Mechanics, Chinese Academy of Sciences (CAS), Beijing, China. Before joining CAS in 2014, he was postdoc at Osaka University and assistant professor at Kyoto University from 2010-2013, after receiving his Ph.D. in Condensed Matter Physics from Tsinghua University in 2010. He is interested in multi-scale modelings and simulations of physics and mechanics of versatile novel solids, with particular interest in physical understanding of deformation in amorphous solids (metallic glass, high-entropy alloy), nanocrystals, and high-temperautre superalloys, etc.

Research Interests

  • Multiscale simulations & modellings of the mechanics and physics of novel solids, e.g. metallic glass, high-entropy alloys, and superalloys.
  • Electronic- and atomic-level understanding of the various material processes, e.g., creep, stress relaxation, dislocation nucleation and motion, vibration and phonon, diffusion, internal friction, as well as the glass transition phenomenon.
  • Overcoming time-scale limitation in atomistic simulations, including accelerated molecular dynamics, nudged elastic band method, machine learning, kinetic Monte Carlo and kART, etc.
