Analyses of galaxy clustering in surveys such as the Baryon Oscillation Spectroscopic Survey (BOSS), have provided robust cosmological measurements such that they are now considered as one of the pillars of modern observational cosmology. In this seminar I will briefly introduce the physics behind these measurements including those made using the Baryon Acoustic Oscillation and Redshift Space Distortion features. I will highlight some recent developments including the results of tests of General Relativity. I will then discuss tests of cosmology that can be made on smaller scales focussing on modelling voids. Future surveys including the Dark Energy Spectroscopic Instrument (DESI), and the Euclid satellite mission, undertaken over the next decade, will provide an order of magnitude more information and I will introduce these surveys and discuss predictions for the expected measurements. Finally, I will review some of the developments required to fully exploit their potential and reach the promised statistical errors.
