Hmm, I happen to attend the school he mentions, though I am not familiar with him, nor do I fit in the criteria of what he is looking for, I would look upon his request with some skeptisism; not really for any reason than he hasn't bothered to respond to any queries here. Obviously that is a concern.
But this research he is doing, assuming he is legit, is governed by some strict regulations and clearances for some ethical boards at the university (the exact acronyms escape me now, I apologize). I'm not a PhD student (yet), but my master's thesis may run into those kind of human research areas; though I've been out of school for 3 months (summer!) and so I am kind of blocked right now.
Just an idea, Darnell, that you should probably ensure that this is cleared with them. If you don't know what I'm talking about, PM me here on susans and I'll get you the required URLs.
Thanks
