DESCRIPTION:Astrophysical (supermassive) black holes (SMBHs) a
 re ultimately characterised by mass and spin. Howe
 ver\, virtually all state-of-the-art hydrodynamica
 l simulations of the assembly of galaxies neglect 
 the spin due to limitations in resolving the gas f
 low in the proximity of the BH. Nonetheless\, spin
  plays a crucial role in modulating both mass accr
 etion and power emission\, driving jet feedback\, 
 and determining recoil velocity of coalescing SMBH
  binaries in response to gravitational wave emissi
 on.\nIn this talk\, I will describe the new result
 s from the recent implementation of a new accretio
 n model that accounts for spin evolution in hydrod
 ynamical simulations of galactic nuclei. I will al
 so discuss\nsome preliminary results on the dynami
 cs and spin evolution in SMBH binaries surrounded 
 by self-gravitating circumbinary discs.
