Main Research Interests:

1. Dynamics of Deep-Sea Mining Pipeline Systems: Focuses on scientific challenges in deep-sea mining operations, including vortex-induced vibrations and control technologies for mining risers, geometric nonlinear large deformation dynamics of flexible hoses, multiphase transport characteristics of minerals in pump-pipe systems, and emergency blockage mitigation methods.

2. Numerical Methods for Fluid-Structure Interaction: Addresses common fluid-structure interaction problems in ocean engineering, including quasi-three-dimensional vortex-induced vibration prediction algorithms for marine risers based on discrete vortex method-finite element method (DVM-FEM), solid-liquid multiphase transport models in pump-pipeline systems based on computational fluid dynamics-discrete element method (CFD-DEM), and fluid/wind-induced vibration response calculation models based on CFD-FEM.

3. Hydrodynamics of Ships and Ocean Engineering: Focuses on performance prediction and motion response issues in ships and ocean engineering, including the resistance, maneuverability, and seakeeping performance of ships and underwater vehicles, hydrodynamics of special surface equipment such as trimarans and amphibious vehicles, and the aerodynamic-hydrodynamic-mooring response problems of floating wind turbines. Additionally, there is active exploration of the application of artificial intelligence (AI) technologies in hydrodynamic problems.
