My research interests focus on the properties of the Universe on the largest scales. The evolution of the Universe is driven by General Relativity acting upon the energy-density components within it. Two important components of the Universe that make up 95% of the energy-density in the Universe, are Dark Matter and Dark Energy, which do not interact with light and hence we infer their presence and properties indirectly.

Surveys of three-dimensional galaxy positions provide a wealth of cosmological information through a number of physical processes that affect the observed positions of galaxies. Over the course of my research career, I have helped to develop two of the primary methods for making robust measurements from galaxy surveys, called Baryon Acoustic Oscillations (BAO) and Redshift Space Distortions (RSD). These techniques allow us to measure the rates of cosmological expansion and the build up of structures within the Universe. Together they allow us to understand Dark Matter and Dark Energy and the physics at work in the Universe on large scales.
