Assistant Professor in Dept. of Materials Science and Engineering, NTU (2020-); PhD in Dept. of Materials, Imperial College London (2019). Research interests include solidification of metals, metal manufacturing process modeling, and numerical approaches for multiphase/multiscale/multicomponent rheological behaviors. My current research focuses on investigating microstructure and defects evolutions during solidification processing and thermomechanical treatments by various analysis approaches such as synchrotron X-ray source for in-situ imaging, electron microscopic observations of polycrystalline materials, CALPHAD-assisted phase identifications, and the coupling between computational fluid dynamics and discrete element method (CFD-DEM). By integrating disciplines such as physical metallurgy, microstructure analysis, thermo-mechanical constitutive modeling, materials dynamics, multiphase rheology, and digital image processing, it is possible to optimize the solidification and thermal process parameters that arise during the manufacturing of high-performance engineering alloys such as steel, aluminum, and magnesium, thus improving manufacturing yields and material properties.

This lab – Solidification Processing and Rheology Lab – combines multiple analysis approaches from solidification metallurgy, microstructure, and mechanical behaviors in order to optimize solidification process parameters. We also investigate a range of microstructural heterogeneity and defects formation induced by complex rheological phenomena during solidification by a multidisciplinary combination among in-situ imaging, coupled two-phase flow simulations, and viscoplastic constitutive model. Deeper insights into solidification defects formation emerging from those approaches are helpful for adding values and improving the reliability of structural materials.
