DESCRIPTION:In times of precision cosmology\, galaxies – the most promin
 ent building blocks of the universe – remain a key challenge in astrophy
 sics.  We still lack the knowledge of a number of physical key processes t
 hat drive the formation and evolution of galaxies.  Large-scale galaxy sur
 veys such as the SDSS have led to tremendous progress in our understanding
  of the local galaxy population by analysing samples containing huge numbe
 rs of galaxies.  The new generation of such surveys\, SDSS-III\, as well a
 s the ongoing experiments Dark Energy Survey and SDSS-IV are taking this a
 pproach to significantly larger distances\, look-back times\, and new spat
 ial scales.  I will present recent results from these surveys discussing t
 he 3-dimensional distribution of stellar population properties in galaxies
 \, the relative roles of self-regulating processes versus galaxy environme
 nt\, and the evolution of galaxy population properties and dark matter fra
 ctions with cosmic time.\n
