Neutrinos are one half of the leptons included in the standard model of particle physics yet some of their properties are the most poorly constrained aspects of the standard model. Neutrinos are also important in the cosmological standard model due to their suppression of the growth of structure at small angular scales and their influence on the evolution of early universe. The cosmic microwave background (CMB) is one of the best probes we have at observing the effects of neutrinos on the growth of large scale structure and by observing those effects we in turn can place tight constraints on two elusive properties of neutrinos, the sum of their masses and the number of different species. In my talk I’ll introduce both properties of the neutrino and the CMB, the effects neutrinos have on large scale structure that leave imprints on the CMB, current and future missions to observe those effects, and my experimental contributions to those missions.
