通常直接说post-doc,大家就知道了,如I'm thinking to do a one-year post-doc at ** university.如果用于正式文件,要写全称"postdoctoral fellow".A postdoctoral fellow (colloquially "post-doc") is a temporary research position held by a person who has completed his or her doctoral studies. Postdoctoral fellows commonly last for periods ranging between six months and five years, and have traditionally been dedicated purely to research; so-called "teaching post-docs" are now being offered for those who seek to focus on teaching in their careers, appointee is typically given a title such as research associate, or sometimes research assistant professor.
