Professor Percival's research interests focus on the properties of the Universe on the largest scales. Surveys of three-dimensional galaxy positions provide a wealth of data both on the physics just after the Big-Bang when the seed fluctuations that will grow through gravity to become galaxies were created, and on the physics driving the evolution of the Universe today.

Large international teams are required to undertake galaxy surveys, and Professor Percival helps to run a number of experiments. In particular, he holds the position of Survey Scientist in the on-going extended-Baryon Oscillation Spectroscopic Survey (eBOSS, www.sdss.org/surveys/eboss), and is a primary science coordinator for the future satellite mission Euclid ([http://sci.esa.int/euclid](http://sci.esa.int/euclid)). He is also working on the Dark Energy Spectroscopic Instrument (DESI, [https://www.desi.lbl.gov/](https://www.desi.lbl.gov/)) and is involved in a number of other experiments and the use of their cosmological measurements.
