Research

Cat is a member of the Department of Applied Mathematics and Theoretical Physics and part of the Atmosphere-Ocean Dynamics research group. Her current research interests are ice-ocean interactions, rotating and stratified flows, and ocean circulation and mixing. 

The melting of ice shelves has important implications for ocean circulation and sea-level rise. However, field observations are scarce due to the extreme conditions. Cat uses high-resolution numerical simulations to model the melting of ice shelves by resolving all but the smallest micro-scales of turbulence. Her research leads into improving the representation of ice shelf dynamics in global ocean and climate models.
