I am a theoretical astrophysicist interested in galaxies, cosmology and cosmic structure formation. My laboratories are the virtual universes produced on supercomputers where I alter the background cosmology and the processes involved in galaxy formation in order to best reproduce the observed Universe.

I am currently involved in a major effort here at ICRAR to produce state-of-the-art simulations of cosmic structure formation, called Synthetic UniveRses For Surveys (SURFS), producing virtual analogues to up-coming surveys like WAVES. Our aim is to model the evolution of millions of small satellite galaxies across cosmic time in a large cosmological volume spanning  a billion light years. Movies and images of these virtual universes and the synthetic galaxies we simulate will soon be found here.

For more information about me and my research, you can find my CV here.

I am also involved in outreach programs, and have contributed to talks at events such as Pint of Science, and presented as a guest lecturer at schools. Feel free to contact me if you are interested in having a speaker for a public event.

I have also produced data analysis tools for the astronomical community, the main one being the VELOCIraptor package, a massively parallel analysis tool for astrophysical simulations, which can be found here.
