I am a computational cosmologist and am interested in large scale structure measurements which can constrain dark energy and modified gravity models. In particular I have worked on modelling redshift space distortions in both LCDM and non-standard cosmologies using dark matter simulations. These simulations allow us to determine the expansion history and growth rate of structure in the universe which are important ways to test the standard model of cosmology.

The PhD thesis "Simulations of Dark Energy Cosmologies" has been awarded a Springer Thesis Prize.
Simulations of Dark Energy Cosmologies
A major outstanding problem in physics is understanding the nature of the dark energy that is driving the accelerating expansion of the Universe. This thesis makes a significant contribution by demonstrating, for the first time, using state-of-the-art computer simulations, that the interpretation of future galaxy survey measurements is far more subtle than is widely assumed, and that a major revision to our models of these effects is urgently needed. The work contained in the thesis was used by the WiggleZ dark energy survey to measure the growth rate of cosmic structure in 2011 and had a direct impact on the design of the surveys to be conducted by the European Space Agency's Euclid mission, a 650 million euro project to measure dark energy.
