As an undergraduate in Canada, I was preparing for a job in the space industry when I learned about radio astronomy and new ways to study the physical extremes of our Universe through pulsars. I completed my PhD on high-precision pulsar timing in Australia before undertaking post-doctoral and academic staff appointments at the Netherlands Foundation for Research in Astronomy (ASTRON), The Centre for Gravitational Wave Astronomy (The University of Texas Rio Grande Valley), and the Centre for Astrophysics & Supercomputing (Swinburne University of Technology). In 2016, I joined AUT as a Senior Lecturer.
I’ve co-authored over 100 refereed journal articles, primarily related to the study of pulsars and fast radio bursts, including 4 in Science and 2 in Nature. I work closely with international collaborators on large, long-term projects such as the Parkes Pulsar Timing Array (PPTA), the International Pulsar Timing Array (IPTA), and the Survey for Pulsars and Extragalactic Radio Bursts (SUPERB). In support of these projects, I’ve led the development of three scientific data analysis packages that are used by the international community of pulsar astronomers (psrdada, dspsr, and psrchive). I am currently leading the design of the pulsar timing instrumentation for the Square Kilometre Array (SKA) as a member of the SKA Central Signal Processor consortium.
PHYS500 – Physics I: Classical Mechanics and Thermodynamics
- Radio astronomy: high-precision pulsar timing; gravitational waves; surveys for pulsars and fast radio transients
- High performance computing: real-time digital signal processing on distributed, multi-processor architectures
- Machine learning: autonomous classification, scheduling, and data modelling for large-scale pulsar surveys
I am primarily interested in testing our understanding of gravity and searching for low-frequency gravitational waves from binary supermassive black holes through high-precision timing of radio pulsars. I have also developed expertise in radio polarimetry and instrumental calibration, statistical methods of studying the pulsar emission mechanism, mapping the structure of the galactic magnetic field through pulsar Faraday rotation measurement, studying interstellar scintillation via the cyclostationary statistics of the electromagnetic radiation from pulsars, and digital signal processing on distributed multi-processor architectures. I also supervise research into the application of artificial intelligence and autonomous systems to all aspects of the search for new pulsars and fast transients.
