The Solar and Magnetospheric Theory group is based within the School of Mathematics and Statistics at the University of St Andrews. Members of our research group are involved in many different areas of theoretical solar and magnetospheric research, as well as data analysis. We are a large group of applied mathematicians who study the Sun and the Earth’s magnetosphere using mathematical modelling techniques. Observational data from satellites and from ground based observatories are often used to constrain our models and improve the validity of our results.
