This question already has an answer here:
I'm a masters degree student trying to figure out how publications and co-authorship work. I know that the school/PI retains legal ownership of any monetary profits that may result from the work, so please don't mention this in your response as it is irrelevant to what I'm asking. I WANT TO BE PUBLISHED AND DO NOT CARE ABOUT MONEY. I just want to ensure that I get academic credit/recognition this time since some of my work was previously passed off as another student's work in a different lab. I'm concerned because the new PI and another professor working on the project seem to want me to do all the grunt work/data collection, but according to the previous student that worked on the project, they prefer to keep the analysis to themselves even though I'm willing [to try] to learn how to do this myself... What protections do student have against others taking credit for their work, not giving them even partial credit/co-author status, and/or allowing another student to take credit who didn't help? Should I mail copies of my data to myself and retain a sealed copy? How do/did (when you were a grad student) you guys protect yourselves? Please list some measures/methods you use to prove that work you did was done by you as opposed to someone else in the lab. As things stand now, it seems like my PI, in theory, could hand over my work to another student who he likes more, who's viewed as younger/more promising, or who has a rich/important Daddy. Not saying he'd do this, but hey, its happened to me before, so yeah - just looking for some solid concrete measures I can implement to protect myself. I don't feel comfortable discusses this with my PI for reasons that should be obvious to anyone with a modicum of common sense, so please don't refer me to my PI. If you can't/don't want to help, fine, but please don't down vote me as somebody else may have some insight that would help me. Thanks.
