Constraining Cosmology with Large Galaxy Surveys

We are entering the industrial age of large galaxy surveys. The next generation of these surveys measure an order of magnitude more cosmological modes compared with their predecessors, and promise tight constraints on cosmological parameters from dark energy to neutrino masses to the initial conditions of the Universe. These gains in statistical precision have been accompanied by improvements in theoretical modeling and analysis techniques. In this talk, I will start by surveying the observables that lead to these constraints. I will then review recent results from the current generation of surveys. I will then conclude by looking forward to upcoming surveys, using the ongoing DESI survey as an exemplar.
