In the next few years, large-scale structure (LSS) surveys will probe the low-redshift universe with unprecedented accuracy. Because there are more modes available at smaller scales, the amount of information about the the universe that we can extract from these surveys depends on our ability to theoretically understand these small, non-linear scales. Among other things, we hope to learn about the early universe (primordial non-Gaussianities) and the late universe (dark energy). The effective field theory of large-scale structure (EFTofLSS) is a theoretical framework that has allowed us to make accurate predictions in the mildly non-linear regime. In this talk, I will briefly review recent progress in the EFTofLSS and explore how it can be used to constrain interactions in the effective field theory of dark energy.
