Bayesian inference
Turning noisy detector data into astrophysics: Bayesian inference, model selection, transdimensional inference, and neural posterior estimation.

I’m a gravitational-wave astrophysicist. I use ripples in spacetime — from colliding black holes and neutron stars — to study the most extreme physics in the Universe: how matter behaves at nuclear densities, how black holes form and pair up, and whether Einstein’s general relativity holds in the strong-field regime. I'm the Deputy Chair of the Board of Astronomy Australia Limited, and I’m Monash node leader in OzGrav, the ARC Centre of Excellence for Gravitational Wave Discovery.

I'm very grateful to have received the Faculty of Science Excellence in Postgraduate Research Supervision award. This one really belongs to the wonderful graduate students I've had the privilege of working with over the years. Thank you all for your curiosity, hard work and good humour, and for making supervision such a rewarding part of the job. A huge thank you also to Eric Thrane, who has co-supervised so many of these students with me.
We're hiring!!! Eric Thrane and I are advertising two, three-year postdoctoral Research Fellow positions at Monash University as part of OzGrav, the ARC Centre of Excellence for Gravitational Wave Discovery. This is a fantastic time to join the field, and the positions are wide open across gravitational-wave astronomy, from LIGO and pulsar-timing-array data analysis, to the astrophysics of black holes and neutron stars, to testing Einstein's general relativity. Check out the full advertisement here. Applications close on Sunday 22 November 2026 (11.55pm AEDT), and please feel free to get in touch with any questions.

Turning noisy detector data into astrophysics: Bayesian inference, model selection, transdimensional inference, and neural posterior estimation.
What gravitational-wave catalogues reveal about how binary black holes form, including distinct subpopulations at different masses.
Post-merger signals, equations of state, magnetars behind short gamma-ray bursts, and continuous waves from spinning neutron stars.
The permanent deformation of spacetime left behind by a passing wave, and how LIGO–Virgo–KAGRA can detect it.
Probing Einstein’s theory in the strong-field regime, from tests of the no-hair theorem to extra polarisations and modified gravity.
Nanohertz gravitational waves from supermassive black-hole binaries, and phase-coherent maps of the gravitational-wave sky.

Pick two masses and listen to the gravitational-wave signal they’d make as they merge.
There’s a signal hidden in this noise. Tune the parameters until the model fits, and watch the likelihood respond.
