Research

I am a member of the Department of Applied Mathematics and Theoretical Physics and the Environmental and Industrial Fluid Dynamics research group. My current research interests are instability, turbulence transition and mixing within the context of ocean dynamics. I also work closely with the Atmosphere-Ocean Dynamics research group.

I have been investigating the applicability of marginal stability to turbulent transitions in stratified shear flows, using numerical simulations of Kelvin-Helmholtz instability. My current work involves simulating the internal wave field of the ocean to identify the key mechanisms by which waves break and enhance mixing. Quantifying properties of the ensuing stratified turbulent flow will also provide insight into small-scale ocean mixing and may help to develop improved parametrisations for global circulation models.
