My primary interests involve many aspects of surface wave generation and propagation, including shelf-scale wave transformation, nonlinear wave-wave interaction, wave breaking and nearshore circulation, and the effects of various bottom types, with an emphasis on cohesive bottom sediments. Recently, I have been investigating the signature of nearshore phenomena (breaking, dissipation and nonlinear dynamics) on the longer term statistics (effect on spectral shape, skewness, and asymmetry). I am also interested in data assimilation, and the ability to invert known or best-deduced dynamics to yield information such as bottom characterization parameters, input conditions and bathymetry.
