Research interests

My research interests center around the broad category of environmental/computational hydraulics and fluid mechanics. In the area of computational hydraulics/fluid mechanics, the objectives of my works are to develop new methods and algorithms, improving their reliability, efficiency, and flexibility to solve the many challenging environmental fluid mechanics problems. My main focus in recent years has been on the latest and revolutionary generation of numerical methods, the mesh-free Lagrangian (particle) methods (e.g. SPH and MPS). The application areas of particular interest in my studies are in the fields of fluvial and coastal mechanics (sediment transport, ice dynamics, water quality, and climate change impact), and multiphase turbulent flows (air-water and multiphase granular flows). The overall goal of my work is to further our understanding of such complex flow systems through a combination of mathematical modelling, theoretical analysis, and experimental/ field measurements.
