Papers, posters, talks and code produced as part of my PhD Candidature at the University of Tasmania and CSIRO Data61.
Investigating the capabilities for astronomy-focused radio interferometers to track near-Earth objects and therefore aid in the prevention of debris-forming collisions in space.
During my candidature, I have taken on several roles that extend this topic, including:
- An internship with Silentium Defence, analysing the performance of their passive radar observatory as applied to space junk tracking.
- Casual work as a telescope operator for the AuScope array, driving VLBI observations for astronomy and geodesy.
- Contract work as a software developer for the University of Tasmania, developing real-time HPC software for satellite detection and Doppler-based location using single-dish inputs.
- Volunteer contribution to Open Source software and standards in the field of VLBI, including a global study on the use of the VDIF data format.
