Our primary research interest is interfacial fluid phenomena at the micro/nano scale and in biological systems. These problems usually require multiscale characterization to achieve physical accuracy and computational efficiency. Dr. Liu has developed novel immersed boundary and molecular dynamics based numerical methods for the simulation of biological and nanoscale systems. His methods have been used in several applications at the bio-nano interface, including design and optimization of Electric Field Guided Assembly (EFGA) of nanowires, linking blood rheology and viscoelasticity to the underlying blood cell aggregation, characterization of flexible valve-viscous fluid interaction and dynamics of an artificial heart. Since 2008, the Liu's group have been exploring the application of particulate and multiphase fluid dynamics in two new areas: Nanomedicine and Biosensing.
