Savitz, David A. (2004). Why Senior Epidemiologists Should Write and Publish Papers. Epidemiology, 15(4)
Career progression and authorship follow a fairly predictable course. The first papers epidemiologists write often reflect opportunities provided by established investigators, frequently using existing data. The junior partner typically is the first author of such papers, with the research mentor listed second or last as a reflection of their valued, important role.
