Research Interest

  • Numerical solution and scientific computing of singularly perturbed time-dependent convection-diffusion-reaction partial differential equations.
  • In my work, I analyzed and established convergence analysis of implicit-explicit (IMEX) alternating direction and implicit alternating direction schemes for singularly perturbed 1D/2D semilinear time-dependent convection-diffusion-reaction problems with non-homogeneous boundary conditions by Finite Difference/Element Methods.
