Prof. Liu earned his PhD degree in University of Wollongong, Australia. His main research interests focus on computational and experimental micro/nano mechanics of metallic materials and composites, novel computational methods (crystal plasticity finite element method) for modeling mechanical behaviour and microstructure evolutions of metals (steel, aluminium, high-entropy alloys etc.) during both quasi-static and dynamic plastic deformation processes. He is also familiar with experimental characterizations of microstructure and mechanical behaviours of metals (steel, aluminium, high-entropy alloys etc.) subjected to different types of plastic deformation, using cutting edge facilities such as EBSD, TEM etc.

In addition, before PhD study, he had 4-year hands-on experience as a manufacturing engineer in a Fortune 500 company, Baosteel (Shanghai). Job included production and process controls, quality management compliance, implementation of 6 sigma black belt projects and conducting new materials research. 

After obtaining his PhD degree, he had worked as a research fellow in Nanyang Technological University for one year focusing on both computational/experimental mechanics/materials study and 3D printing technology.

In 2015, He successfully won JSPS Fellowship from Japan. Therefore, He had worked as a JSPS fellow in the University of Tokyo under the JSPS (Japan Society for the Promotion of Science) Fellowship program for two years. His research included the study of computational (CPFEM)/experimental mechanics of multilayered steel composite and experimental (EBSD)/computational materials science (3D microstructure reconstruction + CPFEM).

In 2017, he went back to Australia and worked as a postdoctoral fellow and sessional lecturer in Swinburne University of Technology. He started developing a new type of gradient nanostructured metallic materials through supersonic impact at cryogenic temperature to improve their mechanical properties. He also took the practice class ' Engineering Materials' for the first-year undergraduates. 

In 2020, he secured a professorship in Noreatern University and subsequently worked as a full professor there.
