I am an ARC DECRA Fellow and Senior Lecturer at Swinburne University of Technology where I lead a research group aiming to solve the mystery of why galaxies stop growing. I use data from some of the world’s largest observatories including NASA’s James Webb Space Telescope to study galactic outflows – explosive cosmic geysers which push huge amounts of gas and dust out of galaxies, starving them of the fuel they need to form new stars. In 2025, I was awarded the Astronomical Society of Australia’s Louise Webster prize for my research showing that most big galaxies in the early Universe had outflows powerful enough to rapidly eject all of their cold gas, potentially leading to their rapid demise.
