Public Lecture: 

Measurements of the Cosmic Microwave Background radiation, and of the large scale structure in the universe, have taught us a great deal about the orgins and content of the universe, but there is still so much to learn. In the next decade we anticipate using new microwave background data, combined with cosmological measurements of the positions and shapes of galaxies, to measure the total mass of the neutrino particles. I will describe a path to making this indirect detection of the absolute neutrino mass scale using the Atacama Cosmology Telescope, Simons Observatory and the Large Synoptic Survey Telescope, which will complement direct measurements. I will also describe how different views of the universe will help us disentangle the signature of neutrinos from signatures of non-standard cosmologies.
