Thanks so much for replying Sneaks and Doodles, I really appreciate it..
To Doodles,
Is he going to a co-author on your papers when you get your results assuming he does contribute to them so what is he worried about?
He will co-author on my papers and since his field is distant from mine and he knows squat about it save some general ideas, he won't make any significant contributions.
I wouldn't assume that just because he's not studying your specific area, he'll not make any significant contributions to a publication. Getting the data and writing it up is only about 20% of a publication in my experience, there needs to be a lot of re-writing, re-scoping, re-arguiing within a publication, particularly if you want it to get into a good journal.
My supervisor isn't studying in my specific area, but she's still very able to supervise me and understand 'what is a phd' and what isn't in terms of structure, amount of work, detail etc.
