DESCRIPTION:Supermassive black holes (SMBHs)\, which reside at the centres
  of massive galaxies and co-evolve with them\, are expected to form binari
 es following galaxy mergers\, a natural outcome of hierarchical galaxy for
 mation. The orbital evolution of these SMBH binaries is driven by a range 
 of physical processes acting across vastly different length scales: from k
 iloparsec separations\, where the dynamics of merging galaxies dominate\, 
 down to sub-parsec scales where interactions with gas and\, eventually\, g
 ravitational wave emission become the primary drivers of orbital decay. In
  this talk\, I will present an overview of the key hardening mechanisms th
 at govern SMBH binary evolution\, highlight recent progress in the field\,
  and share insights from my own research on the dynamics of these systems.
