Research Interests

Coupling of the solar wind with the Earth's magnetosphere, and the impact of this interaction on the upper atmosphere, through processes collectively referred to as 'Space Weather'.

Magnetospheric substorms: a phenomenon involving the storage and explosive release of solar wind energy in the magnetosphere, resulting in the visible aurora and enhanced atmospheric electrical current systems.

Electrodynamics of the mid-latitude ionosphere, that is typically magnetically conjugate to the inner magnetosphere and radiation belts. 

Geomagnetic storms, where the auroral zone expands equatorwards to more inhabited latitudes where the effects of Space Weather are more readily apparent.
