Biography

16 years experience in space physics research and tertiary teaching. Research has spanned the areas of ultra-low frequency (ULF) plasma wave signatures, associated mathematical modeling of ULF wave effects in the ionosphere and magnetosphere, and the dynamics of the auroral currents and electromagnetic energy budget derived from the Iridium constellation magnetometer and SuperDARN radar data. Designed and operated induction and fluxgate magnetometer systems and was data manager for the NewMag payload on FedSat, developing algorithms to provide error-free timing of that data. Have ~70 peer reviewed publications in space physics, awarded ~$4M in ARC-DP and LEIF funding, supervised 15 MSc and PhD students and am an associate editor of Journal of Geophysical Research Space Physics.

Collaboration

• Co-Investigator on the MICE, CubeSat project at Johns Hopkins University Applied Physics Laboratory
• Co-Investigator on CARISMA, the Canadian ground magnetometer array, for remote sensing plasma mass density in the magnetosphere
• Co-author on book contract (Wiley) on remote sensing the magnetosphere using ULF variations
• Development of spherical harmonic cap and elementary current methods applied to Iridium satellite constellation data, including the recently, NSF funded AMPERE project
• First to combine the Iridium satellite data with SuperDARN radar data to show input Poynting flux over both the northern and southern auroral zones.
• First results of Birkeland current location and intensity control by the interplanetary magnetic field (using Iridium satellite data)
• First use of Iridium, SuperDARN and ground magnetometer data to provide ionosphere conductance estimates over large spatial areas of the auroral ionosphere
• Revision of FITACF algorithm (SuperDARN) to improve spectral width estimates from radar data
• First modelling of ULF wave propagation through the ionosphere that includes inductive Hall effects and oblique geomagnetic field effects, predicted phase distortions in radio astronomy interferometer signals
• Developed time dependent, 2-D models of ULF wave propagation that includes a realistic ionosphere/atmosphere system. Present ARC-DP grant will extend this modelling to time dependent 3-D, in collaboration with University of Minnesota, USA.
