If you've got a really persistent biter like that, then you probably need to escalate the ignoring to leaving the room. Putting the dog in a time out works for some cases - but to do it, you've still actually got to give the dog some attention

Thus, what can actually be more affective is to remove yourself instead. The dog jumps/bites - you can indicate your displeasure with a sharp "Ah!!" and turn away, crossing your arms and examining the ceiling. But if the dog persists, then just walk away out the room and shut the door. No speaking, no eye contact, just walk away and leave her isolated. About 5 minutes should do it, let you collect yourself, before returning for another go. And every time she bites, you get up and leave her.
