Cosmological observations provide constraints on the neutrino sector that are model-dependent, but potentially very strong under a set of reasonable assumptions. I will give an overview of recent cosmological constraints on the neutrino number density, the sum of the neutrino masses and the presence of sterile neutrinos, together with a discussion of the underlying assumptions. I will briefly summarise the expected sensitivity of future experiments to neutrino parameters.

The video of the presentation will be available shortly after the event.
