Definition · Plain-language
Postdoc
A postdoc, or postdoctoral researcher, is a professional academic who has completed their doctoral studies and is engaged in temporary, self-directed research. This position serves as a transitional career stage designed to refine research skills, publish scholarly papers, and prepare for a permanent university lectureship or industrial research role.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
The Strategic Role of Postdoctoral Research
A postdoctoral position serves as a critical bridge between graduate study and a permanent academic career. For most PhD graduates, transitioning directly into a tenure-track lectureship is exceptionally rare. A postdoc provides the time and resources required to build a competitive academic portfolio. During this period, researchers focus on converting their doctoral thesis chapters into peer-reviewed journal articles, presenting findings at international conferences, and establishing their scientific independence. Crucially, it allows scholars to diversify their methodological expertise by working in different laboratories or research groups, thereby expanding their professional network.
Securing Postdoctoral Funding and Fellowships
Postdoctoral positions are funded in two primary ways: principal investigator (PI) grants or independent fellowships. PI-funded roles are tied to specific research projects, where the postdoc is hired to execute a pre-defined research agenda. While these positions offer stable salaries, they may limit intellectual autonomy. Conversely, independent postdoctoral fellowships—awarded by national funding bodies such as the UK Research and Innovation (UKRI), the Wellcome Trust, or the European Research Council (ERC)—provide researchers with the freedom to design and conduct their own projects. Securing such prestigious external funding is highly valued in academia and significantly enhances a researcher's long-term career prospects.
Mentorship, Supervision, and Professional Transitions
In addition to conducting independent research, postdocs are expected to contribute to the broader academic environment. This often involves mentoring PhD and master's students, managing laboratory operations, and occasionally undertaking light teaching duties. The dual status of postdocs—being neither students nor permanent faculty—can present structural challenges, particularly regarding job security and short-term contracts. Therefore, active career planning is essential. Successful postdocs use this transitional phase to develop transferable skills, such as grant writing, project management, and public engagement, which are highly sought after in both the higher education sector and private industry.
Key facts
At a glance
- Postdoctoral positions are temporary, contract-based research roles for individuals who hold a PhD.
- They focus heavily on scholarly publication, methodological expansion, and developing research independence.
- Funding is typically sourced from a principal investigator's research grant or through competitive personal fellowships.
- Postdocs are classified as university staff members rather than students, receiving salaries rather than stipends.
- The role serves as a common prerequisite for tenure-track lectureships and senior research careers in industry.
Common misconceptions
What people often get wrong
Often heard: A postdoc is an advanced student working towards another academic degree.
Actually: A postdoc already holds the highest academic degree (a PhD) and is a professional employee focused on research, not a student.
Often heard: Postdoctoral research must be conducted at the same institution where the PhD was completed.
Actually: Academia strongly encourages postdocs to move to different universities or countries to broaden their research perspectives and networks.
Often heard: Teaching is the primary responsibility of a postdoctoral researcher.
Actually: While some postdocs choose to teach to build their portfolios, their primary contractual obligation is to conduct research and publish findings.
