What Is a Postdoc?

Read time 5 minutes

Published on Sep 18, 2025

A postdoc, also known as a postdoctoral researcher, is a scholar who undertakes a temporary period of continued academic research following the completion of a doctoral degree, usually a PhD. The term postdoc can also refer to the fellowship position that a postdoctoral researcher may occupy at a university.¹

If you're thinking of earning a PhD or are already in the process of doing so, you may be wondering, What’s next? If you decide to pursue a postdoc fellowship, you’ll have further opportunities to develop your research, refine your skills and work under the direction of a mentor before pursuing a more permanent position in academia.

What are a postdoc’s main benefits, and is it right for you? Learn more about postdoctoral research to decide if this is the path you should take.

Postdoc Meaning: Overview and Definition

Before considering pursuing a postdoctoral fellowship, it’s important to fully understand what a postdoc means and how it might fit into your career pathway following the completion of a PhD. The postdoc gets its name from the period of time in which it takes place; a postdoctoral fellowship or position takes place after the individual has completed a PhD.

Becoming a postdoc or completing a postdoctoral research fellowship does not confer any additional degrees. Typically funded by universities, postdoctoral research positions allow for the hiring of scholarly researchers to continue work on their research projects for a pre-determined period of time.¹ A postdoc fellow may also publish their research findings and may attend academic conferences, perhaps presenting their work there.

During their time in the position, a postdoc researcher works closely with a mentor, such as a tenured university professor or researcher. They’ll have opportunities to develop their research skills further under the mentor’s guidance. If the postdoc researcher is in a STEM field, they may also have opportunities to help manage a lab.

What exactly does a postdoc spend their time on? It varies, but may include the following:

Conducting experiments, analyzing the results and conducting other forms of research
Applying for grants
Meeting with other researchers
Reading published literature
Helping with the management of a lab (for STEM postdocs)

What is postdoctoral research? It varies considerably, depending on the postdoc’s chosen field and interests within that field. Postdocs may work on their mentor’s research project, and they may also have opportunities to develop their own independent research.

What Is a Postdoc’s Place Within Your Career Pathway?

A postdoc takes place at the end of your academic journey and the beginning of your professional career. It provides a transition between earning academic qualifications and becoming a contributing member of your field.

To have an idea of how a postdoctoral fellowship might fit into your career pathway, it may be helpful to evaluate the overall progression of your academic career.

Here is a typical example:

Earn a bachelor’s degree
Earn a master’s degree
Proceed to a PhD program, conduct original research and become a doctoral graduate
Apply to one or more postdoctoral fellowship positions and continue your PhD research or, more likely, begin research in a new topic or a new direction under the guidance of your mentor
Pursue a teaching and research position at a university, working toward becoming a tenure track professor

The length of a postdoc fellowship varies. Six months is on the shorter end. More commonly, postdocs will be funded for two to three years, or occasionally longer.¹

What's the Difference Between a Postdoc and a PhD?

There are many differences between postdoctoral vs. PhD programs. A PhD confers a degree, and the postdoc fellowship does not. A PhD requires coursework, and the postdoc position does not. The postdoctoral researcher has already earned a PhD, whereas the PhD candidate is in the process of earning one.

Furthermore, a PhD candidate is a student, whereas the postdoctoral researcher is a temporary employee who works with greater independence and self-direction. Instead of culminating their research in a dissertation as the PhD candidate does, the postdoc researcher will disseminate their findings through scholarly publications and perhaps academic conferences. Because of these differences, postdoc fellows are expected to already have solid research skills, whereas PhD candidates are expected to acquire them.

Common Goals of Postdocs

Another way to compare a postdoctoral vs. PhD program is to consider their main goals. While a PhD student’s main goal is to earn the PhD, a postdoc fellow’s main goals are to gain experience, benefit from continued mentorship and publish.

There are many reasons to consider applying to a postdoctoral research position, including the following:

Academic development: Conducting postdoctoral research provides opportunities to improve your research skills further.
Experience: You’ll be able to gain some work experience as a postdoc researcher, which can provide a launch pad for pursuing your professional career. Many postdoc fellows have the goal of pursuing a tenure track professorship.²
Resume: Completing a postdoc may bolster your resume and set you apart from other job applicants. Having a postdoc fellowship on your resume might help you in your pursuit of positions at nonprofit research organizations, government agencies, research-focused corporations and other entities.²
Publications: A postdoctoral fellowship typically provides opportunities to publish your research.
Networking: You’ll be able to build your professional network in your research position.
Mentorship: Postdoc fellows work under the direction of a mentor, who can provide advanced guidance on research and career matters.
