I have been invited to do a review paper for a journal, but I don't know whether it would be ethical for me to do so since I am a student researcher (and therefore belong to a university lab under somebody's supervision). Are there any ethical issues surrounding this? I would not be using any data (original or otherwise) from my laboratory in the paper. It would simply be based on my own expertise in a related but distinct field (my lab is in biology, but the paper is biochemical one in nature). Your input would be much appreciated since I do not want to offend or overstep any boundaries.
