I am a researcher and lecturer in the Department of Physics and Astronomy at Macquarie University, Sydney, Australia. I specialise in using radio telescopes to investigate the interstellar medium, with a focus on magnetism and star-formation in the Milky Way.

I am particularly interested in using statistics and machine learning to unlock discoveries in 'big data' from new telescopes and surveys (e.g., ASKAP, POSSUM, GLIMPSE). These techniques are broadly applicable and I also work on cross-disciplinary problems in ecology and remote sensing.

Here you can find information on my research, software, teaching and outreach.


The Friendly Virtual Radio Interferometer is Python software designed to simulate astronomical observations by arrays of linked radio antennas.

RM-tools is a suite of scripts to analyse Faraday rotation in polarised radio-continuum data. Written in Python, it is available on GitHub.

IR & radio images.

CORNISH is a 5 GHz radio-continuum survey of the Galactic Plane. Observations on the VLA were tailored to find ionised bubbles around young stars.

NH3 in the Galaxy

The H2O southern Galactic Plane Survey imaged dense molecular clouds in 3D by detecting water and ammonia.
