I am very interested in multidisciplinary research related to numerical analysis and scientific computating. My major research areas are on numerical methods (mainly FEM) for PDEs from different disciplinaries. Work include singularly perturbed problems, surface and groundwater modeling, parallel computing with MPI and C++, image processing, radial basis meshless methods, inverse problems, high-order compact difference schemes, Maxwell's equations in metamaterials. My research has been supported by Air Force, NSF, NSF EPSCoR, and NASA EPSCoR.
