The Andromeda Galaxy is the Milky Way’s galactic neighbor, and is an excellent place to study how spiral galaxies are formed and how they evolve.  The Panchromatic Hubble Andromeda Treasury (PHAT) is providing the most in depth view of this galaxy yet with observations from the Hubble Space Telescope.  This survey covered over 1/3 of the galaxy and resolved over 150 million individual stars.  After a broad overview of the survey, I will discuss how we have identified thousands of star clusters, how we obtain their ages and masses, and how these clusters are helping us understand various astrophysical processes such as star formation and the lifetime of molecular clouds.
