Quasar feedback - the influence of the black hole on the overall properties of its host galaxy - has been invoked to explain many properties in today's galaxies such as the scaling relations between the black hole mass and the bulge properties or the high end galaxy mass function. In the last few years there have been widespread efforts to find physical evidence for such feedback.

I will show results from studies of dust-reddened quasars, an early phase in a luminous quasar's life, in which we find signatures for powerful quasar outflows either in the ionization lines in the UV or in the molecular lines in the far-infrared. These outflows are powerful enough to influence the gas properties in the host galaxy and therefore the star formation efficiency. I will present statistical evidence of such effects and detail future efforts of characterizing the importance of such outflows on the overall properties of the host galaxy.
