Abstract: 
Present and upcoming surveys of the late time Universe allow increasingly precise cosmological measurements. This makes it possible to characterize further our theory of gravity and fundamental cosmological assumptions. I will first discuss how large-scale effects relevant for upcoming galaxy surveys contribute to constraining our theory of gravity in the context of statistically homogeneous and isotropic models. I will then examine purely geometrical functions based on distance modulus and expansion rate observations, and their implications for the validity of a statistically homogeneous metric.
