My research covers shelf sea and deep ocean fluid dynamics, diagnosed from both observations and numerical model simulations. I have a specific interest in flow-topographic interactions (including internal wave generation, breaking, and the resulting turbulent mixing), particularly at the continental shelf break and in areas of complex bathymetry such as submarine canyons and seamounts. My interest in these hydrodynamic processes is motivated by their interdisciplinary impacts, including biogeochemical fluxes, sediment resuspension, and ecosystem response. In addition to conventional ship-borne instrumentation and oceanographic moorings, I use a variety of cutting-edge autonomous platforms and sensor systems, including microstructure and Lab-on-Chip biogeochemical sensor equipped autonomous ocean gliders. I have led numerous Seaglider missions worldwide as well as multi-platform observational campaigns in challenging environments.
