Biography

I graduated from Coventry University with a BSc in Applied Mathematics and Theoretical Physics. My final year project involved the development and numerical simulations of a generalised shallow water model for rotating flows with a turbulent Ekman layer.

Project title : 'A two-dimensional model for Oceanic and Atmospheric flows with a turbulent Ekman layer'

I am now a member of the EPSRC Centre for Doctoral Training (CDT) in Fluid Dynamics here at Leeds. During the first year of the course my MSc project involved the development and numerical modelling of a flood demonstration model - 'Wetropolis'.

Memberships/Fellowships

Associate member, Institute of Physics

Teaching Interests

Python is a very versatile language and I am keen to help support mathematicians develop their skills using it. I supervise weekly workshops of the module 'MATH2920 - Computational Mathematics' which is an introductory programming course for mathematicians.

Project outline

Convection within the Earth’s fluid core generates the planetary magnetic field. Seismic, geomagnetic, and geodynamic observations indicate that lateral variations in heat flow are imposed on the core at the top boundary. Heterogeneous boundary conditions at the top of the core can significantly reorganise the pattern of convection, this project will investigate the influence of this boundary control on the flow dynamics.

This project aims to investigate how boundary forcing impacts the flow speeds and length scales by developing scaling laws for these quantities. In turn, these scaling laws can be used to infer details about the force balances present in the system. The long term goal is to investigate if these dynamics can be used to explain observed features of the Earth’s magnetic field.
