I am a student in physical oceanography in Leif Thomas's group. I am interested in studying the physics of ocean circulation to seek a better understanding of its role in the Earth system and its impacts on our climate. My work combines geophysical fluid dynamics theory, numerical modeling, and observational data. Prior to arriving at Stanford, I received my MSc in Applied Mathematics at ENSEEIHT, in France.

Current Research and Scholarly Interests
Mixing in the abyssal equatorial Pacific Ocean is thought to play a major role in upwelling dense water and closing the deep branch of the meridional overturning circulation. However, little is known about the mechanisms driving its spatio-temporal variability. Recent observations of small-scale turbulence obtained in the eastern equatorial Pacific show evidence of intense abyssal mixing over smooth topography. It has been hypothesized that the intense mixing could have been driven by surface-generated equatorial waves trapped and amplified near the bottom as a result of the horizontal component of the Coriolis parameter, fh, and weak abyssal stratification. In this work, we test this hypothesis by using the MITgcm, a quasi-hydrostatic, nonlinear numerical model, that allows for non-zero fh. In our simulations, Equatorially Trapped Waves (ETW) are generated in the upper water column and propagate freely into the weakly stratified abyss where the effects of fh are most strongly felt. These non-traditional effects trigger the formation of sharp beams and lead to enhanced shear in the abyss, and subsequent low Richardson numbers. Such features are more prominent at the inertial latitude where the IGW beams undergo critical reflection over the flat seafloor. A suite of numerical simulations allows us to explore the sensitivity of this mechanism to key parameters of the wave and its medium. Using a mixing scheme, we provide quantitative estimates of its potential contribution to mixing in the abyssal equatorial Pacific Ocean.
