My research lies at the intersection of applied mathematics and geophysical fluid dynamics, and my focus is to develop novel mathematical techniques in support of atmosphere and ocean science, from fundamental theory to numerical simulation to data assimilation and forecasting. My main mathematical tools are multiscale and stochastic modeling, asymptotic methods, and numerical analysis; my primary application area is physical oceanography.
