DESCRIPTION:Thanks to revolutions over the past few decades in how we imag
 e the sky\, astronomers have been able to detect ever fainter galaxies in 
 our cosmic backyard. Some of these are fainter than a single giant star an
 d - whilst visually unimpressive -  they are extremely important tools in 
 our quest to understand (1) how galaxies form and (2) what our Universe is
  made up of. In this talk\, I will review how we use observations of the f
 aintest galaxies to probe the nature of the Universe. I will show the work
  my group are doing to detect the faintest galaxies\, measure and constrai
 n the properties of dark matter\, and to understand how star formation and
  reionisation progressed in the very early Universe.\n
