My research area is partial differential equations and its applications, which consist of two parts, one is the theoretical analysis and the other is numerical analysis, including simulations and scientific computations. I am interested in the global existence and blow-up solutions of the time dependent partial differential equations, mathematical modeling and applications related to ordinary and partial differential equations, such as reaction-diffusion equations, traveling waves, soliton and shock waves, radar beams and heat transfer and fluid dynamics. My research interests also include the numerical approximation in wireless communication areas to model and analyze the characteristics of various wireless systems. The following topics are my research work:
