My main research  theme is ocean physics, mostly related to ocean renewable energy (tides and waves), climate change, and coastal problems (e.g. flooding and erosion). I use a combination of numerical models and  observational techniques (i.e. ship-based or satellite-based data) to study ocean physics.  I am interested in mathematical and numerical modeling of waves, and free surface flow from watersheds to coasts. I also work on sediment transport under the action of waves and currents. Another branch of my research  concerns with  numerical modeling of flow in the vicinity of  structures. I apply new and powerful numerical techniques such as Differential Quadrature Method, Radial Basis Function Based Meshless methods (Multiquadric and RBF-DQ) and Smoothed Particle Hydrodynamics (SPH) to model the flow field.  I also use open source structured/unstructured ocean/wave models such as ROMS, TELEMAC, SWAN and ADCIRC  in my research.
