Field and analytical studies of marine environmental hydrodynamics with emphasis on mathematical modelling of nearshore waves, currents and shoreline evolution. Active microwave remote sensing of ocean dynamics including wave/wave, wave/current, wave/topographic interactions with recent work in signatures of surface ship wakes and naturally occuring ocean surface processes. The development of in situ and remote oceanographic instrumentation and data acquisition systems designed to measure the spatial and temporal structure of coastal boundary layer flows.
