I study the geophysical fluid dynamics (GFD) of the ocean and atmosphere, with a particular focus on the dynamics of planetary boundary layers at the ocean submesoscale (horizontal scales of 0.1-10 kms), where both nonlinearity and planetary rotation are important. These small spatial scales are particularly challenging for traditional observational and computational methods, and understanding the dynamics of the ocean submesoscale remains among the most pressing open challenges in oceanography and GFD. My work suggests that processes at these scales also have wide-ranging effects on the broader ocean circulation, from boundary-layer turbulence to the gyre-scale circulation, with implications for ocean biogeochemistry, climate, and improving the accuracy of large-scale ocean models. In my research I use a combination of theory and a hierarchy of numerical modeling approaches, including state-of-the-art high-resolution numerical simulations, aimed at gaining deep insight into physical processes. These insights are then extended to more complex physical settings through collaborations with observationalists and large-scale numerical modelers, with the goal of connecting ocean dynamics to broader interdisciplinary problems.
