The question of how to choose PhD committee members has already been asked and answered in general terms, but I have the following more specific questions regarding the choice:
Is it more important that your advisor already know your committee members or that you do (e.g., your advisor knows them but you've never met them before vs. you know the member but your advisor doesn't have a strong or pre-existing relationship with them).
Is it better to get someone in your discipline or someone doing more related work (e.g., if you're getting a computer science degree, you ask computer science faculty vs. you're getting a computer science degree but everyone except for your advisor is from the English department)?
Should you pick people who are already invested/interested in you succeeding or is the dissertation process supposed to be a chance for you to win people over to your side?
