Research and expertise

My research is focused on computational hydraulics and applications. I have developed high-performance mathematical and numerical models to facilitate sustainable management of hydrosystems interrupted by natural hazards such as floods, tsunamis, debris flows and landslides.

  • Numerical methods: Godunov-type finite volume scheme, discontinuous Galerkin methods (DG methods), smooth particle hydrodynamics, particle-tracking methods, coupled hydrodynamic model and discrete element method for floating debris and mass flows, high-performance computing
  • Modelling dynamic processes of extreme natural hazards to support risk assessment and damage estimation
  • High-resolution urban flood modelling and blue-green infrastructure for flood risk mitigation and resilience
  • Catchment systems modelling (rainfall-runoff, flash flooding, water quality, hydrogeomorphology, landslide, debris flow, floating debris, engineering intervention, etc.) for natural flood management
  • Real-time flood forecasting
  • Crowd-sourced data acquisition, agent-based modelling and coupled human and natural systems modelling
  • Application of AI / deep machine learning in hydroinformatics

Background

Profile

I graduated from Dalian University of Technology, China in 1997 with a BEng in Port and Waterway Engineering (four-year first degree programme). After spending three years in the construction industry, I came to the UK in September 2000 to study for a DPhil in University of Oxford, followed by one-year postdoctoral research in the same research group between 2005 and 2006. During my time in Oxford, I also worked as a colleague lecturer in St Edmund Hall of Oxford University.

I joined Newcastle University in March 2006 as a Lecturer in Hydraulic Engineering, and was subsequently promoted to Senior Lecturer in 2011 and Professor of Hydrosystems Modelling in 2013. Then in June 2018, I took up my current position as Professor of Water Engineering in the School of Architecture, Building and Civil Engineering at Loughborough University.
