  • RESEARCH INTERESTS

    Numerical Analysis of Discontinuous Galerkin (DG) Finite Element Methods:
    I am mostly interested in the primal DG methods such as NIPG, SIPG or IIPG.

  • Elliptic equations with discontinuous coefficients
  • Parabolic equations: with or without convection term, with degenerate diffusion
  • Linear equations: elasticity, quasi-static and dynamic viscoelasticity equations, acoustic and elastic wave problem
  • Nonlinear equations: Navier-Stokes equations, miscible displacement, two-phase flow, three-phase flow, nonlinear non-Fickian diffusion in viscoelastic polymers
  • A posteriori error estimation
  • Slope limiters on unstructured nonconforming meshes

  • Multiphase Flow: Simulations and Analysis
    Two-phase flow: Sequential approach v. fully coupled approach, mesh and time adaptivity, DG methods, 2D/3D simulations, gravity, well models.
    Three-phase flow


    Incompressible Flow: Simulations and Analysis
    Stokes equations, Navier-Stokes equations, subgrid eddy viscosity turbulence model, DG method and classical finite element methods (FEM).


    Multi-numerics and/or Multi-physics Approach

  • Coupling of Stokes and Darcy using DG
  • Coupling of steady-state Navier-Stokes and Darcy using DG
  • Coupling of time-dependent Navier-Stokes and Darcy using DG
  • Coupling of time-dependent Navier-Stokes and Darcy using FEM
  • Coupling of DG and MFE for single phase flow (elliptic problem)
  • Coupling of DG with MFE for coupled Stokes and Darcy
  • Coupling of DG with FEM for coupled steady-state Navier-Stokes and Darcy

  • Medical Applications

  • Inflammation and sepsis: Center for Inflammation and Regenerative Modeling
  • Modeling of cell migration in Necrotizing Enterocolitis
  • Modeling of binding of LPS with TLR4 and signaling cascade

  • Miscible Displacement Problem

  • Convergence of backward Euler in time with high order DG in space
  • Convergence of DG in time with mixed finite element (MFE) in space
  • Numerical simulation for unstable flow
