Oral title: The signature of AGN feedback on the global star-formation properties of AGN over z~0-3 Oral abstract: In this talk I will present our latest results on the star formation properties of X-ray selected AGN at both low (z~0) and high (z~1.5-3.0) redshift, utilising sensitive Herschel and ALMA data. I will show how the star-formation properties of the X-ray AGN population, particularly the distribution of star-formation rates, are consistent with those expected from AGN feedback predicted by a leading hydrodynamical simulation (EAGLE). I will discuss these results in the broader context of the role of AGN in the formation and evolution of galaxies.
