Assistant Professor Department of Mechanics and Aerospace Engineering   Research Group

Dr. Ju Liu graduated from Xi’an Jiaotong University with a bachelor’s degree. He then pursued his graduate study at the Institute for Computational Sciences and Engineering (ICES) of the University of Texas at Austin, where he obtained his Ph.D. degree in 2014. After a short stay at ICES as a postdoctoral scholar, he went to Stanford University for postdoctoral training. In Dec. 2020, he joined the Department of Mechanics and Aerospace Engineering at the Southern University of Science and Technology as an assistant professor.

His research work focuses on computational mechanics, fluid-structure interaction, biomechanics. Some research highlights are listed in below.

(1) He and collaborators developed a rational mechanics modeling framework for liquid-vapor phase transition. Based on that model, he developed a structure-preserving, nonlinearly stable finite element formulation and a parallel computing software. This work may serve as a theoretical and computational basis for the understanding of phase transition phenomena, which includes evaporation, boiling, condensation, etc.

(2) He constructed a new continuum modeling framework for fluid-structure interaction. In particular, this framework provides an elegant and unified strategy for handling nonlinear incompressible finite strain elasticity as well as its coupling with fluids. It may simplify the computational modeling for monolithically coupled fluid-structure system; it can be used to solve various elastic/inelastic problems with incompressible constraint; it may provide a more robust strategy for predicting the onset of instability in solid/structure mechanics.
