DESCRIPTION:Supermassive black holes (BH)\, which reside in the center of 
 most massive galaxies since the dawn of structure formation\, are usually 
 surrounded by a dense stellar component. If\, by chance\, a star gets too 
 close from the central BH\, the former can be disrupted by the tidal force
 s of the latter\, resulting in a luminous event known as a tidal disruptio
 n event (TDE). With a dozen of observations to date\, and many more to com
 e\, TDEs will soon allow statistical studies of BHs and their environment.
  I will begin with a brief introduction on TDEs. I will then discuss the k
 ey parameters affecting the rate at which stars are disrupted\, and how we
  can use the TDE rate to better understand the BH mass function or the typ
 ical stellar density in the vicinity of BHs. I will finally show how TDEs 
 could contribute to the growth of BHs and the formation of quasars at high
  redshift.\n
