DESCRIPTION:Different modes of AGN feedback are now considered key process
 es in the evolution of massive galaxies by regulating black hole and galax
 y growth. Indeed\, a wealth of observational evidence demonstrates that fe
 edback from supermassive black holes impacts the galaxies and the halos th
 ey inhabit on a wide range of scales: from the central parsecs to hundreds
  of kpc. What we are still far from understanding is how AGN feedback coup
 les with the host galaxy\, which is what ultimately determines its efficie
 ncy. The aim of the QSOFEED project is to answer this question by quantify
 ing the impact of multi-phase quasar-driven outflows and jets on the nucle
 ar regions of galaxies\, which have the same dynamical timescales as the A
 GN-driven outflows and jets. I will present recent results based on high a
 ngular resolution data from cutting-edge telescopes including Keck\, GTC\,
  and ALMA. We do not find evidence for a significant impact of quasar-driv
 en winds/jets on the total molecular gas reservoirs and star formation rat
 es\, but they are undoubtedly modifying the distribution of cold molecular
  gas and young stellar populations (ages < 100 Myr) in the central kpc of 
 the galaxies.
