Research Interests:

My main research focus is numerical simulations of structure formation in the Universe.
Starting from our understanding of the very early universe, I perform simulations of a wide range of scales: how dark matter collapses and forms the seeds of galaxies, how the large-scale filamentary network of galaxies arises from the counteracting forces of the expansion of the universe and the pull of gravity; how the largest collapsed objects in the universe - clusters of hundreds and thousands of galaxies - form and evolve and what we can learn about our universe from those most extreme objects; and how galaxies form as part of the large-scale structure that feeds them with gas. I am also interested in developing numerical simulation techniques that allow us to answer questions about the universe both more precisely and more efficiently.
