DESCRIPTION:Cosmological perturbation theory plays an essential role in un
 derstanding the formation of large-scale structure (LSS) of the universe. 
 \nOn a fairly large scale (long-wavelengths)\, the cosmological fluctuatio
 ns can be treated perturbatively using the fluid description. Effective fi
 eld theory methods allow us to integrate out the nonlinear\, small-scale\,
  modes where the physics gets increasingly complex (dark matter halo dynam
 ics\, galaxy formation\, baryonic physics\, etc.). We will discuss the per
 formance of the approach in light of the current and upcoming observationa
 l surveys.
