Dr Andrew Gascoyne is a lecturer in the School of Mathematics and Computer Science. Prior to that I worked as a postdoctoral research associate at The University of Sheffield on the STFC funded project entitled "Magnetic Features and Local Helioseismology".

Magnetohydrodynamics, Helioseismology, Solar Physics, Mathematical Modelling.

‘’Numerical solution of the 2D wave equation with Gaussian initial condition and reflecting boundary conditions.’’

Solar physics, which is the branch of astrophysics that specialises in the study of the Sun. I am focused on Helioseismology, the study of acoustic wave propagation within the interior of the Sun, and MHD (magnetohydrodynamics) wave propagation. Mathematical modelling is a vital part of this research in order to compare and predict observational signatures and understand the many complex mechanisms and processes involved in the interaction of the solar acoustic modes with magnetic elements on the Sun i.e., Sunspots and Plage regions.
