I work on stably stratified turbulence using analytical methods and direct numerical simulations (DNS). Most of my research consists of fundamental studies of turbulence in stratified fluids, with applications to the flow structure, the energy distribution, the energy transfers and the mixing of heat/salinity in the ocean pycnocline.

I received Bachelor and Master degrees from the University of Cambridge, Department of Engineering (UK). I completed my PhD in the same department at Cambridge in 2013.

Enstrophy $(1/2)|\omega|^2$ (log-scale) on a vertical slice through a DNS of stratified turbulence with forcing. Sub-portion of slice through a cubic domain of $2048^3$ points. Kelvin-Helmoltz-type instabilities can be clearly seen, e.g. in the bottom-left corner of the image, as well as regions of intense enstrophy and small-scale turbulence. The colormap used is one of the colormaps of the cmocean package by Kristen Thyng (Texas A&M University), available freely for MATLAB or Python.
