Abstract:  Cosmology has entered the precision era: we now have a standard model
for cosmology where the content, history and evolution of the Universe
are described by few parameters. These parameters are constrained by
observations at the percent level or better. As for particle physics and
the search for beyond the standard model, the next development is to
test for possible deviations from the standard model like for example
constraining neutrino properties. In the past few years there have been
new developments in the effort of constraining neutrino properties with
cosmology. The Cosmic Microwave Background has been measured with
renewed in improved precision and large-scale structure surveys have
mapped cosmological structures in the Universe over unprecedentedly
large volumes. Future, massive large-scale structure survey have been
presented and approved. On the theory side, a significant effort has
been devoted to achieve better modelling of small scale clustering and
of cosmological non-linearities. As a result it has become clear that
forthcoming cosmological data have enough statistical power to detect
the effect of non-zero neutrino mass (even at the lower mass scale limit
imposed by oscillations) and to constrain the absolute neutrino mass
scale. I will present some recent work on constraints on neutrino
properties from cosmology, touching upon present and possibly future
constraints.
