Biography

I am interested in understanding both how the Universe behaves on the largest scales and which new tools will be required to answer outstanding questions about it. I research galaxy clusters, the largest gravitationally bound objects in the Universe, and design aspects of the next generation of radio telescopes. My group has recently adopted a multiwavelength approach to understanding clusters and superclusters. We are using several of the world’s best radio telescopes in Australia, the US and India (ATCA, VLA and GMRT). Optical data and X-ray images from the ESA XMM-Newton satellite are used to understand how cluster mergers (the most energetic events since the Big Bang), shape the galaxies within them.
