  • Magnetic Fields in Protoplanetary Discs 

    Leung, Philip
    Protoplanetary discs are flattened discs of gas and dust surrounding young stars that are believed to be the sites of planet formation. They are believed to be threaded by large-scale magnetic fields, which significantly ...
  • The Dynamics of Geophysical and Astrophysical Turbulence 

    Cope, Laura
    Turbulence is ubiquitous within geophysical and astrophysical fluid flows. Its interaction with physical ingredients such as rotation and stratification gives rise to spectacular dynamics, including the layering of material ...
  • Solitons and dualities in 2+1 dimensions 

    Walton, Edward
    We examine three topics in the physics of three-dimensional systems, paying particular attention to the roles of topological field theory, topological solitons, and duality. First, we consider the dynamics of nonrelativistic ...
  • A cross-scale model for the evolution of influenza within a single season 

    Karamitsou, Venetia
    In this thesis we develop a mathematical cross-scale model for the evolution of influenza within a single season. We model evolution as the emergence and spread of a mutant strain in a population that is already invaded ...
