I am transitioning from junior to senior researcher status. I have several publications as first author, many as coauthor, and a few as senior (last and corresponding) author.
As people perceive differently the role of authors according to their position, especially when looking briefly at a scholarly paper, I am wondering when it is most appropriate to transition from first to senior author.
Does it depend on biologic age, academic age, ranking, tenure, or what else?
My field of interest is cardiovascular research, but I think that a general answer followed by some details on the main different academic fields would be beneficial for ACADEMIA readership.
