Where to find Ashley Williams on the Normandy 2?

I asked Ashley Williams to join my crew on the Normandy and she is a selectable member for my squad.

The strange thing is I can't seem to find her on the Normandy spaceship. It does not really make sense.

Is there a glitch possibly? This is for the PC version on Origin.

Solution 1:

She is lying down on the floor on the left hand side of starboard observation deck, it took me ages to find her because you can't see her when you enter because she is behind the couch.

Solution 2:

She should be on the Crew Deck in the Starboard Observation deck - source

Depending on where you are in the game she might be having a bad hangover on the floor
