- 1博士後（的）
This word describes work, study, or a job that comes after finishing a doctoral degree (a PhD, the highest kind of university degree). A "postdoctoral researcher" (often to "postdoc") is someone who already has a PhD and keeps doing research, usually for a few years, before getting a full professor job. It's a formal, academic word — you'll see it around universities and science, not in everyday conversation.
From the word’s history
From post- + doctoral.
post-（之後）加 doctoral（博士的）。
組成post- (after) + doctoral (relating to a doctorate degree)
