Edward's position as part of S.T.A.R.S. in Resident Evil 0 is Rear Security.
If you're having trouble remembering who he is, he's the guy who turns into a zombie aboard the Ecliptic Express (too vague perhaps?).
I'd really like to be able to go over all of his escapades in the game, but sadly he shows up not a few minutes in and already he's been torn to shreds.
That said, there's a certain heart-wrenching scene involving Edward you can see if you play as Rebecca at a certain point, try and find it in the game if you can!
