I am a computational cosmologist whose research centres around the study of galaxies and their formation. I employ extremely large, hydrodynamical simulations of large volumes of the Universe to understand what physics is important in shaping the properties of the galaxies we see all around us. Understanding the huge diversity in galaxy properties represents one of the biggest challenges in current astrophysics and ongoing advances in computational power are making is possible for the first time to study this puzzle in fine detail.
I am interested in all aspects of the galaxy formation process. My recent research has been focused on two areas: firstly, in leveraging extremely large simulations to understand how violent outflows from the supermassive black holes that live in the centre of virtually all galaxies are able to regulate the growth of the galaxies themselves. Secondly, I am interested in the 'flip side' of the galaxy formation process: the properties of the gas and heavy elements outside of galaxies. How and when did the heavy elements that we observe in the intergalactic medium escape from the galaxies where they were born?
