Welcome to my home page. I'm a Professor of Astrophysics in the School of Physics at the University of Sydney.

My main research areas are galaxy evolution (i.e. studying how galaxies form and change over cosmic time) and active galaxies. At the moment, I'm trying to learn more about the feedback mechanisms which link the energy output of a galaxy's central black hole to global properties like the star-formation rate.

Much of my research is based on the analysis of data from large-area optical and radio surveys of the sky, and I've been involved in designing and carrying out several major astronomical surveys. I'm currently leading the ASKAP-FLASH project, which aims to use the new Australian SKA Pathfinder (ASKAP) telescope currently under construction in Western Australia to learn about more about the amount and distribution of neutral hydrogen gas in very distant galaxies.

I've also worked on (and remain interested in) other research areas including galaxy dynamics, supernovae, gamma-ray bursts and the stellar population in the central bulge of our own Galaxy. You can find some information about my research here (or click on the Research tab at the top of the page).

I'm currently President of Division VIII (Galaxies and the Universe) of the International Astronomical Union and Chair of the National Committee for Astronomy.

I was elected as a Fellow of the Australian Academy of Science in 2010.
