Research interests
I focus my research studies designed to understand behaviour of nonlinear waves, internal waves, hydrodynamic instabilities and mixing. My research is very numerically oriented and theoretical in nature. High resolution numerical simulations, using a fully-nonlinear, nonhydrostatic numerical model, are being done to study a variety of processes related to internal waves. These include such things as wave generation by tidal flow of topographic features such as bank edges and sills, the evolution of shoaling solitary waves and tidal flow over a sill. Mathematical models, such as those based on weakly-nonlinear theory, are also used to study problems related to internal solitary waves. This provides a framework for interpreting and understanding the results of numerical simulations.
