Our theoretical understanding of galaxy clustering has improved significantly over the past 5 years. In the context of standard cosmological models based on GR, we now have a well-defined approach for absorbing all the complicated, incompletely understood physics of galaxy formation into a set of free parameters, the bias parameters. Following the effective field theory paradigm, the various contributions are classified by order in perturbation theory as well as number of spatial derivatives. I will review these developments, and discuss the implications for galaxy clustering as a robust probe of cosmology.
