DESCRIPTION:In this talk I will review some recent progress in theoretical
  modelling of the nonlinear structure formation and show how it can be use
 d to extract cosmology from current and future spectroscopic galaxy survey
 s. As an example I will present cosmological parameter measurements from t
 he publicly available Baryon Oscillation Spectroscopic Survey (BOSS) data 
 on anisotropic galaxy clustering in Fourier space. Assuming a minimal LCDM
  cosmology with varied massive neutrinos and imposing the big bang nucleos
 ynthesis prior on the physical baryon density\, the measured late-Universe
  parameters are: Hubble constant H_0 = 68.6 $\\pm$ 1.1 km/s/Mpc\, matter d
 ensity fraction Omega_m = 0.319 $\\pm$  0.015\, and the mass fluctuation a
 mplitude sigma_8 = 0.75 $\\pm$ 0.05\, independently of the cosmic microwav
 e background observations.
