DESCRIPTION:Gravitational potential of large-scale structure of the\nUnive
 rse generates a deflection of the paths of the CMB photons as they propaga
 te from the last scattering surface to the observer. This gravitational de
 flection causes a re-mapping of the primary Gaussian CMB temperature\, an 
 effect known as CMB lensing\, which can be detected and measured with the 
 current generation of CMB experiments. As this effect strongly depends on 
 the gravitational potential of large-scale structures which are in turn in
 fluenced by late universe parameters such\nas neutrino mass or curvature\,
  CMB lensing offers a new powerful probe to constrain cosmology.\nIn this 
 talk\, I will present some techniques used in the full-sky reconstruction 
 of the lensing potential with Planck\, and investigate the importance of n
 on-Gaussianities induced by CMB lensing in cosmological\nparameter estimat
 ion.\n
