Authorship dilemma: Grading prof won't let me add my actual lab PI to the paper?
Hey everyone, I'm an MSc chem student caught in a weird authorship dispute and could really use some advice. For my mandatory project course, my grading professor told me I'll only get an S grade if the work gets published. His lab didn't really have the setup I needed, so I approached another PI in the department and did all the actual bench work, synthesis, and data analysis under their supervision. Now, my grading professor is refusing to allow the other PI's name on the final paper. I want to do the right thing since the other PI actually guided the chemistry and deserves authorship. Can I just submit the manuscript to my grading professor as a standard internal project report to get my grade, and then officially submit it to a journal later with the PI who actually helped me? I don't want to violate any research ethics or burn bridges in the department, but I'm completely stuck. Has anyone navigated this before?
