My primary focus is in Space Weather. Currently, my main research question focuses on quantifying the level and significance of electron precipitation out of the Van Allen radiation belts into the Earth's atmosphere. I have led the development of modelling tools such that we can understand experimental measurements in terms of the magnitude of the changing precipitation flux levels. I have also gained expertise in working with and understanding satellite measurements of the electrons trapped in the Van Allen belts. Working with my close collaborators from the British Antarctic Survey, we have ~15 radio receivers in the Arctic and Antarctic which we use to undertake long range remote sensing of the Earth's upper atmosphere; and hence detect particle precipitation. We collaborate with other groups, to determine the significance of this precipitation to the chemistry of the atmosphere. While my work is primarily "basic" Space Physics, our work has shown that it links to the wider understanding of the Earth's climate, and hence improving modelling of the climate in a CO2 dominated future.
