I'm just curious, when schools say that one (or any) of the LOR's need to be from a faculty member, is it implied that it has to be from a science faculty member, or can it be from any professor/instructor?

How about a letter from your PI ? I work (volunteer technically) in one of the research labs at school.
This probably wont win me points for knowledge, but what is a PI again?

No worries !
A PI is a Principal Investigator. He/She is the head of the research lab. They all have PhDs and are considered staff so I thought their LoR might be worth something ? 😀

Yes. You can submit up to 4 LOR's on pharmcas according to pages 40 and 41 on http://www.pharmcas.org/docs/Instructions201011.pdf .I just have to ask.. is there a limit to the # of LOR's you can submit to pharmcas?
