DESCRIPTION:In the 1920s Hubble recognised that massive galaxies exist in 
 predominantly two types - spirals or ellipticals. It was also recognised v
 ery early on that elliptical galaxies are typically "dead"\, they have ver
 y little ongoing star formation linked to very low cold gas and dust conte
 nts\, while spiral galaxies have more cold gas and are still forming stars
 .  One of the biggest open questions in extragalactic astronomy is what ca
 uses some galaxies to shut off their star formation\, potentially with a c
 oncurrent morphological transformation\, while others don't. Our ability t
 o quantify the changing demographics of the galaxy population has progress
 ed substantially in the last couple of decades\, thanks to large multiwave
 length and spectroscopic surveys probing ever deeper into the Universe. Ho
 wever\, we still can't pinpoint exactly what processes are responsible for
  this galaxy transformation. I will present our recent work on post-starbu
 rst galaxies\, one type of transition galaxy that provides clues about how
  star formation might have quenched in a significant fraction of the galax
 y population. \n\n
