Research
My main research interests lie in the field of Numerical analysis, applied mathematics and scientific computing,
• Design and Analysis of numerical methods
– Direct discontinuous Galerkin methods, Mixed discontinuous Galerkin methods, finite element methods, Finite diffrente methods, Graded meshes
• Numerical solution of nonlinear Partial Differential Equations, such as Elliptic equations (e.g.,PoissonBoltzmann equation, Biharmonic equation), timedependent PDEs ( SwiftHohenberg equation, and CahnHilliard equation), singular problems
• Asymptotic method for Kinetic equations (e.g., BhatnagarGrossKrook (BGK) equation)
