List of research topics
Current research projects

Professor Sheng develops and utilizes advance multi-dimensional multi-species experimental methods to study flow structure interactions (FSI) in unsteady conical flows over deforming boundaries, turbulence wall interactions, environmental boundary layer, microscale flows, hydrodynamic interactions of microorganisms and surface, hydrodynamics of swimming and bio-mimetic locomotion, and biomedical related near surface transport.

Applications include flow control and drag management using actuated surfaces for MAV, microscale coherent structure identification in rough wall turbulent boundary layer, hydrodynamics of bacterial biofilm formations and irrigations, hydrodynamic interactions between physical environment and biological system, cardiovascular flows, transport of micro-circulations, and intra-cellular micro-fluidics. Professor Sheng’s research focuses first on advancing the latest experimental techniques: 3-D holographic PIV, tomographic PIV, digital holographic microscopy, 3-D fluorescent light field microscopy and volumetric flow accelerometer.

The primary objective is to establish the capabilities in obtaining high resolution 3-D and multiple component measurement. The research also emphasizes on applying these new techniques to advances our understanding of flow wall interactions with strong engineering and biomedical implications. Current projects focus on near wall flow structure manipulation via a moving surface with roughness element, developing measurement method to understand two-way coupling of unsteady flow and deforming vascular wall, hydrodynamic interactions of chemotactic bacteria with the wall during biofilm formation and biofilm irrigation using micro-fluidics, and multi-scale investigation of planktonic flows during predation.
