By this, I do not mean I did not obtain significant research results. My supervisor has told me to finish up a draft of paper for submission, I wrote it, then after few months, he told me to correct some parts and did more experiments on certain area, I followed all his instructions and wrote a second draft to him. And until now, it is already one year after sending my draft to him, and still I have no idea when he will publish it.
Actually, this not only happens to me, it happens to all the members in my research group. The average time my supervisor publishes our results is about 2-3 years after we have finished all the required experiments. The results just become idle. I would like to ask, if this is a common phenomenon (and the possible reasons behind it), if not, what I (and my colleagues) can do about it? You know as a research student, having publication is very important, it is really frustrating.
