Education

  • PhD, 2000, The University of Manitoba, Winnipeg, Canada, Groundwater hydrology.
  • M.Sc., 1996, International Institute for Hydraulic and Environmental Engineering, Delft, Netherlands, Hydrological Engineering.
  • B.Eng., 1985, China University of Geosciences, Wuhan, China,  Geophysics.

Research Interests/Activities

  • Developing parallel computing codes for large-scale, multi component, multiphase fluid and heat flow simulation.
  • Large-scale (multi-million-gridblock model) modelling study for groundwater flow and contaminant transport in saturated/unsaturated porous and fractured media.
  • Flow focusing and discrete flow path study for understanding flow allocation mechanisms and patterns in unsaturated fractured media and assessing the frequency and flux distributions, and contaminant transport pathways.
  • Developing/Applying numerical algorithms (such as Lanczos algorithm, Arnoldi algorithm, and Kalman filtering) for groundwater flow and contaminant transport modeling.
