Biography

I am a PhD student at the University of Leeds under the supervision of Dr Phil Livermore, Dr Jon Mound and Dr Ciaran Beggan. Before my PhD I studied at Utrecht University, where I obtained degrees in Earth Sciences (BSc) and Geophysics (MSc). At Leeds, I am a member of the Deep Earth Research Group, while I also collaborate with the Geomagnetism team at the British Geological Survey.

Research Interests

My research concerns secular variation of Earth’s magnetic field, and I focus on how recent changes are generated from within Earth’s core. Specific research topics include:

  • Developing new methods to improve field forecasts;
  • The importance of magnetic diffusion for secular variation, relative to core fluid flow;
  • The evolution of the reversed and normal field, and their impact on the recent decay of the axial dipole field;
  • The control of core-mantle boundary heat flow on the triggering of magnetic polarity reversals.
