Faculty of Sciences, Engineering and Technology

* Upper Atmosphere: 

  • Ionospheric variability; 
  • Effects of the ionosphere of solar and geomagnetic disturbances;
  • Travelling Ionosopheric Disturbances (TIDs) and causation by Atmospheric Gravity Waves (AGWs) or polar geomagnetic Field-Aligned-Currents (FACs);
  • Observation and measurement of TIDs and other ionospheric variability by SuperDARN high-frequency (HF) radars (particularly Buckland Park near Adelaide) and support sensors for the Jindalee-Operational-Radar-Network (JORN);
  • Effects of ionospheric variability on technological systems (JORN, HF comms, HF direction-finding, GPS/GNSS positioning, spaceborne synthetic aperture radar);
  • Effect of technological systems on upper atmosphere (e.g. ionospheric heaters, EMP);


* Space Environment and effects on Spacecraft

  • The space radiation environment at Low Earth Orbit (LEO) in the Ionosphere, Medium Earth Orbit (MEO) in the inner radiation belt (Magnetosphere) and Geostationary Orbit (GEO) in the outer radiation belt (Magnetosphere);
  • Charging of spacecraft by keV Ionospheric electrons and electrostatic discharge (ESD);
  • Single Event Effects (SEE) on spacecraft electronics by MeV protons in LEO (South Atlantic Anomaly) and MEO/GEO;
  • Deep Dielectirc discharge (DDD) within spacecraft electronics by MeV electrons at GEO;
  • Focus on potential radiation effects for the upcoming DST Buccaneer Main Mission (BMM) spacecraft and those within the STaRShot Resilient Multi Mission Space program;


* Geomagnetism and Geophysics

  • Geomagnetic observations, variability (e.g. storms, resonances, pulsations);
  • Geomagnetic survey and effect on quality of geomagnetic disturbances; 


* Spaceborne and Airborne sensors

  • Magnetometry; 
  • Synthetic Aperture Radar (SAR);
  • Ground Penetrating Radar (GPR);


* CUAVA - Cubesat and UAV, ARC ITTC (Industry Transformation Training Centre)


Co-I since 2016
