Dr Sarah Bentley

VC Fellow

Department: Mathematics, Physics and Electrical Engineering

I graduated from Durham University with an MMath in 2013. After about in a year in industry working on a geometry system which underlies computer aided design software, I began a PhD at the University of Reading in 2015. As part of the space weather group inside the Meteorology depatrment, the focus of this work was to understand and predict the driving of magnetosphere-scale ULF waves by the solar wind in order to use in space weather models. I stayed on at Reading as a post-doctoral researcher in order to further this work and in 2020 joined Northumbria as a Vice-Chancellor's Fellow. In addition to continuing the various directions of my research, this provides me with the opportunity to develop my teaching and research proposal writing skills.

Due to my mixed backgrounds in space physics, meteorology, maths and geometry, I have a wide range of interests. I am still interested in the prediction of ULF waves and the resulting radial diffusion in Earth's radiation belts. However, I am also investigating a variety of techniques drawn from other fields, such as machine learning/artificial intelligence, optimisation and stochastic/probabilistic approaches to this problem, and how geometric structures combined with data assimilation can be used to efficiently model geomagnetic phenomena that underpin the co-ordinate systems used in space weather prediction.
