Personal profile
Key Research Interests
I am a theoretical astrophysicist. The main focus of my research is neutron stars: the collapsed remnants of a normal star's core following a supernova. The physics needed for a full description of a neutron star is very broad, encompassing (magneto)hydrodynamics, superfluidity, elasticity, general relativity and nuclear physics; I am interested in all of those, to a greater or lesser degree, but particularly in anything related to the star's magnetic field. As a theorist, my research methods are analytic (i.e. pen and paper) or numerical (i.e. running computer code), though it is all motivated by the rich and growing spectrum of neutron-star observations.
Biography
After finishing an undergrad degree in Maths and Physics at Warwick University, I joined the General Relativity group at Southampton University. There I worked towards my PhD, supervised by Ian Jones, and became interested in stellar magnetism. Following that I had three postdoc positions - at the universities of Tübingen (Germany) and Southampton, and at the Copernicus Astronomical Centre in Warsaw - as well as various short-term stints elsewhere, including at the Albert Einstein Institute (Potsdam, Germany), the Anton Pannekoek Institute (Amsterdam) and in Santiago de Chile. Finally, I joined the UEA in January 2020 as a lecturer.
