Hi Editor,
PI=Principal Investigator. This is a common term in grant writing. But you can define it early, and then use PI.

The text was first edited, some few paragraphs by ProfessorEdit. There are some features that he put in the file, so when I add the Human Subjects chapter, it came out weird.

I need editing, English is not my first language, but I need the file "released" from special features, so I can use it.

Thank you. Please ask more questions, so we get a good product!
