Postdoctoral researcher

Post-doctoral researchers by discipline (United States, 2012)

A postdoctoral researcher, post-doctoral researcher or postdoctoral fellow is a person professionally conducting research after the completion of their doctoral studies (typically a PhD) as part of a temporary academic appointment, sometimes in preparation for an academic faculty position. It is intended to carry out research and further deepen expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualifications or certification, while in other countries it does not.

Postdoctoral research may be funded through an appointment with a salary or an appointment with a stipend or sponsorship award. Appointments for such a research position may be called postdoctoral research fellow, postdoctoral research associate or postdoctoral research assistant. Depending on the type of appointment, postdoctoral researchers may work independently or under the supervision of a principal investigator. However, a designated postdoctoral research appointment may also be taken up when other suitable positions are not available, rather than merely pursuing the deepening of scholarly experience. In many English-speaking countries, postdoctoral researchers are colloquially referred to as "postdocs".
