Research interests:
Applied mathematics, models from physics and engineering, such as optical systems, metamaterials,
plasmas and BoseEinstein condensates. These physical models are described by
differential equations such as the nonlinear Schrodinger equation, complex Ginzburg Landau
equation, short pulse equation. My research mainly involves existence, stability and
dynamics of solitary wave solutions. Methods employed include asymptotics, variational
approximations, rigorous analysis, numerical analysis, as well as scientific computing.
