Abstract: This line of research is devoted to the statistical analysis of the large-scale distribution of galaxies as observed in spectroscopic and photometric redshift surveys. It entails the theoretical modelling of matter and halo/galaxy correlation functions with analytical predictions from cosmological perturbation theory and their comparison against results from numerical N-body simulations. The goal is the optimal estimation of the cosmological parameters describing the Standard Model, including neutrino masses, as well as extensions due to modified theories of gravity, dark energy, general relativistic effects and non-Gaussian features in the early Universe.
