Faber was also the principal investigator of the Nuker Team, which used the Hubble Space Telescope to search for supermassive black holes at the centers of galaxies. One of her most recent works include the addition of a new optical spectrograph for the Keck II telescope, which saw its first light in 1996. The new addition would increase the Keck II's power for observing far-away galaxies by 13-fold. She has also joined up with other scientists to create the CANDELS project, which is the largest survey of the universe taken by the Hubble Telescope.
