DESCRIPTION:Cosmological perturbation theory plays an important role in un
 derstanding the formation of large scale structure (LSS) of the Universe. 
 On a fairly large-scales (long-wavelengths)\, the cosmological fluctuation
 s can be treated perturbatively using the fluid description. EFT methods a
 llow us to integrate out the nonlinear\, small-scale\, modes where the phy
 sics gets increasingly complex (dark matter halo dynamics\, galaxy formati
 on\, baryonic physics\, etc.). In the talk\, I shall give an overview of s
 ome of the current developments and status of the field. We will conclude 
 by showing the performance and parameter constraints in light of upcoming 
 galaxy surveys and I will indicate some future directions.
