Research Interests:

My research centres on the analysis and interpretation of data from spacecraft particle and field instruments and ground-based magnetometer and ionospheric radar data. Current research activities include:

ULF waves

Ultra low frequency (ULF) waves are an important coupling mechanism between the magnetosphere and the ionosphere since they transfer both energy and momentum. These processes are most significant in the high-latitude ionosphere, where the magnetosphere-ionosphere interaction is strongest. The waves also act as an important diagnostic of magnetospheric morphology and dynamics. High frequency radio experiments, such as SuperDARN and spacecraft such as Cluster are providing exciting new information on ULF waves.

Solar wind-magnetosphere coupling

The large scale transport of mass, momentum and energy into the Earth's magnetosphere-ionosphere system from the solar wind is mainly controlled by processes at the dayside magnetopause. These processes cause transient flows in the high latitude ionosphere, which can be studied with the SuperDARN radars, and auroral emissions which may be imaged from the ground, or by space-borne auroral imagers.

Magnetospheric substorms

Much of the energy which enters the Earth‚s magnetosphere through processes at the dayside magnetopause is eventually released into the nightside upper atmosphere through magnetospheric substorm processes. High frequency (HF) ionospheric radars have proved to be a powerful technique for investigating the spatial and temporal development of the ionospheric conductivities and electric fields during the three phases of the magnetospheric substorm. New, multi-instrument studies are providing a new set of opportunities for understanding the complex dynamics of the nightside magnetosphere.
