Standing in the core of the MWA

I am an Australian radio astronomer based at Leiden University, where I am a Veni Fellow specialising in studying radio stellar systems and detecting star-exoplanet interactions. I am also appointed to the Netherlands Institute for Radio Astronomy (ASTRON).

I completed my PhD in astrophysics at The University of Sydney in 2017. My PhD was focussed on understanding radio galaxy evolution and developing the Murchison Widefield Array (MWA), a Square-Kilometre Array (SKA) precursor. I was also a CSIRO Astronomy and Space Science student. My main supervisors were Professor Bryan Gaensler (University of Toronto), Professor Ron Ekers (CASS).

While continuing my interest in radio galaxy evolution during my de Bruyn fellowship at ASTRON, I shifted my focus to understanding radio emission from stellar systems. In particular, I am using the high sensitivity of the all-sky survey being conducted by LOFAR to survey stars and exoplanets at low radio frequencies.

I have given astronomy and general science talks to a range of audiences, including school students, amateur astronomy clubs, professional astronomers, and the general public (to both Dutch and international audiences). I believe that it is the responsibility of a tax-payer funded scientist to be a science communicator to the public, so if you need an astronomer or scientist to present a talk please do not hesitate to get in contact with me. I was also a casual guide at Sydney Observatory.

I also have an interest in the application of Bayesian statistics and Markov Chain Monte Carlo (MCMC) methods to a range of problems, with a speciality in model inference. These skills allow me to robustly leverage the most information out of large data sets. If you have an idea for an interesting application of such skills, let me know!

Outside of science, my interests vary from reading, politics, independent cinemas (films and projection devices), running, rugby league, the gym, and drinking too much beer.
