How to get rid of annoying graduate student "supervisor" I am an undergraduate student who has developed a novel new model which according to my PI (principal investigator) will have a high impact.

My PI assigned a grad student to supervise me. Supervision consisted of meeting once a week to update him on my progress so far. Sometimes he would provide certain helpful suggestions(none that are actual innovations just slight fixes/alterations that would improve the model).

During the course of the year he (the grad student) has become more and more annoying. Unhelpful suggestions/requests, etc.

During our last meeting the grad student made some bold claims on the model developed by me claiming to be an equal author/developer. He made it clear he wanted to get a large amount of credit for the model (co-authorship).

I do not think that he has done enough meaningful work to deserve credit for the model (although he would be listed in acknowledgements). Knowing his intentions I wish to distance myself from him(including not having him review the paper), as to lower his chance of becoming a co-author.

I would like to achieve this in such a way that does not negatively impact my relationship with my PI, as grad schools require reference letters.

EDIT:
I don't think I have been very clear and for that I apologize. I acknowledge that he has contributed to the work. I also understand that having more authors doesn't reflect badly on me(I didn't even know about the score system). I just have problems with his claims of equal authorship. As we are nearing final results/submissions of paper and he has better relation with the professor he may try to take the first authorship position.

Additional: By my university guideline policies about co-authorship he has not done enough to deserve even a co-author position.

Great!

Less great. Much less great. Let me make something clear here: this is not your project alone, this is the project of you, your advisor, and the PhD student. The guy has invested a serious amount of time into this project (not as much as you, clearly, but still a significant amount), and now you have unilaterally decided that he is to be cut out when the time comes to publish your results? Likely, this is not to be going over well either with him or the advisor, and for good reasons.

Deteriorating professional relationships are never fun, but it is simply not feasible to decide midway through a project that you now would rather not have another researcher on board. If he has already made contributions to the project, and it certainly sounds like he has, it would be unethical to publish without him now.

EDIT: to make it clear, I am not saying that he should get equal credit to you. But it certainly sounds like he should get some credit.

The very least you need to do is follow user11192's recommendation:


  it is best to meet with your advisor (and possibly the grad student) to discuss an authorship plan.


Finding a "sneaky" way to get rid of the grad student before publication time is not particularly ethical, and has a pretty high possibility of backfiring on you.
