The Cosmic Microwave Background (CMB) contains a wealth of information about the fundamental properties of the universe, from the early stages of the Big Bang to the formation and growth of structure during later times. Together with Suzanne Staggs, Lyman Page, and Jo Dunkley, I work on the development and characterization of new detector technologies and data analysis techniques for two ground-based CMB observatories: the currently deployed Atacama Cosmology Telescope and the upcoming Simons Observatory. By probing both small and large-scale fluctuations in the temperature and polarization spectra of the CMB using these highly sensitive instruments, we hope to gain a better understanding of the physics of the nascent universe, the evolution of dark matter, and the nature of dark energy.
