My research focuses on the microstructure modeling guided design of damage-tolerant high-strength steels, involving the experimental and numerical investigation of the multiscale mechanical properties of steels, and bridging the microstructure and mechanical properties as well as the component performance by integrated computational materials engineering (ICME) approach.

The microstructure and mechanical property characterization involving grain/phase levels and plastic deformation/damage mechanism analyses are achieved by microscopy techniques and micro-/macro-mechanical testing. The general numerical simulation methods are representative volume elements, crystal plasticity modeling, macroscopic damage and fracture modeling, finite element methods, etc.

Currently, I also research on the additive manufacturing steel in terms of understanding their process-microstructure-mechanical properties relationship.
