About me

A physical oceanographer with a flair of geophysical fluid dynamics and data science. I have a strong interest in (sub)mesoscale turbulence in the surface ocean and how it interacts with the large-scale ocean circulation and biogeochemistry. I approach the problems by analyzing big data outputs from general circulation models, idealized numerical simulations and remote-sensed observations.
