DESCRIPTION:From the electron mass to the top-quark mass\, the masses of e
 lectrically charged fundamental fermions span over six orders of magnitude
 . Neutrino masses expand this range by another at least six orders of magn
 itude. Further\, it is a puzzling fact that there exist several similariti
 es and differences between the masses and mixing patterns of different fer
 mion flavours. While the standard model of particle physics can successful
 ly account for the observed fermion masses\, it does not shed any light on
  this puzzle. Some of its extensions\, originally proposed for the unifica
 tion of fundamental interactions\, provide a more appropriate platform to 
 address this puzzle by unifying also the fundamental fermions. In this tal
 k\, I will review some of the grand unified theory based attempts to under
 stand and resolve the flavour puzzle. Examples of approaches based on new 
 symmetries will be discussed. Alternative proposals based on theories in h
 igher spacetime dimensions will also be discussed.\n\nhttps://indico.ific.
