Late-time observational cosmology is coming of age. With the unprecedented power of current and upcoming surveys, we will not only produce excellent constraints on the standard model of cosmology, but also pin down the properties of extensions to that model, such as dynamical dark energy, modified gravity, and massive neutrinos. I will discuss the state-of-the-art in testing and constraining these phenomena using weak gravitational lensing and galaxy clustering measurements. I will then describe the challenges and opportunities involved in making precise and accurate tests of fundamental physics using surveys such as the ongoing Dark Energy Survey (DES) and the next-generation flagship Large Synoptic Survey Telescope (LSST).
