I’m an astrophysics PhD candidate at the University of Southern Queensland, working on asteroseismology and stellar evolution, with a particular focus on δ Scuti stars.
About
I'm an astrophysics PhD candidate at the Centre for Astrophysics, University of Southern Queensland, where I study the pulsations and evolution of δ Scuti stars.
My research is primarily computational. I build large grids of stellar evolution and pulsation models to understand how oscillation frequencies change with stellar properties such as age, mass, composition, and rotation. I then use these models to interpret observed pulsations and constrain the properties of real stars, particularly young and intermediate-mass stars.
A substantial part of my work involves developing the computational tools needed to do this at scale, from high-performance computing pipelines and large model datasets to emulators and statistical inference.
Before starting my PhD, I studied at the Australian National University, where I worked on the evolution of millisecond pulsars formed through accretion-induced collapse and investigated whether such a population could contribute to the Galactic Centre gamma-ray excess.
I also have a strong interest in reproducible research, open-source software, and scientific computing.
