I have an article I'm writing where I'm the senior author, but I also did the majority of the work and wrote the paper. I have two co-authors who have also contributed.
In my field (physical sciences) the norm is that the senior author goes last and the person who wrote the paper/did the majority of the work is first author. Everyone else goes in between.
What should the order should be in this situation when lead and senior author are same person?
