Cosmological data from the next generation of cosmological surveys such as Euclid and LSST have the statistical power to distinguish modified gravity or dark energy models from LCDM, as well as determining neutrino masses. But with excellent data come formidable challenges in analysis. In this talk I report on recent advances that attempt to ensure that any evidence for new physics is well...
That the universe is statistically isotropic when averaged over large scales is a foundational `principle’ of the standard cosmological model. Recent surveys of the distribution of galaxies and studies of the CMB now make it possible to test this - with some intriguing results.

As the Planck space mission is delivering its final results, it has become clear that much is still to be learnt from observing the polarization and electromagnetic spectrum of the Cosmic Microwave Background Radiation. In the light of current results and remaining questions, I will discuss the scientific case of future CMB projects and how to address the challenges of measurement accuracy and...
