Becoming a Postdoctoral Researcher

Written by Hannah Slack

For many individuals, becoming a postdoctoral researcher represents a significant milestone in their academic careers. Often referred to as research assistant or research associate roles, these positions offer you the chance to consolidate the knowledge and skills gained during your PhD.

Ready to dive into what a postdoc is and determine if it's the right next step for you? Let's explore everything you need to know about becoming a postdoctoral researcher –from what the role involves to the funding and application process.

What is a postdoc?

A postdoc, or postdoctoral research position, is a temporary, funded role typically based at a university or research institution. Commonly, these positions are sponsored by Research Councils, supporting individuals to work in specific institutions.

Although postdoctoral researchers are considered university staff, they often work under supervision and in teams led by senior academics. Unlike a PhD, a postdoc does not culminate in a thesis or viva. Instead, the focus is on producing results and disseminating findings through publications and conferences.

Postdoctoral vs PhD

Let’s looks at the key differences between a postdoc and a PhD. Although both roles involve extensive research, a PhD focusses on completing original research culminating in a thesis, which must be defended.

A postdoc, on the other hand, involves completing advanced research projects but does not end with a thesis or a defence. Postdoctoral researchers are expected to publish their findings and often partake in teaching and mentoring activities, bridging the gap between learning and contributing new knowledge.

Why pursue a postdoc?

There are several reasons why you might want to pursue a postdoc:

  • Further research: it offers an opportunity to complete any unfinished research or pursue lines of enquiry excluded from your doctoral thesis.
  • Skill development: it helps in honing specialised research skills and gaining expertise needed for a career in academia or industry.
  • Networking and reputation: a postdoc provides a platform to network within the academic community and build a solid professional reputation, essential for securing future positions or funding.
  • Career progression: for those aiming for a permanent academic role, postdocs serve as a stepping stone, enabling continuous professional development and experience.

How does postdoc funding work?

Typically, postdoctoral researchers are externally funded by large research organisations such as the UKRI Research Councils. Alternatively, funding can come from universities or private companies. The funding body determines the length of the contract and the nature of the research to be undertaken based on grant applications.

Postdoc salary

In the UK, the average postdoc salary is approximately £34,124. Unlike PhD stipends, postdoc salaries are taxable income. As an employee, you may also contribute to pensions and be eligible for student loan repayments. Additionally, you’ll have access to benefits offered by your employer, such as healthcare or insurance.

What does a postdoctoral researcher do?

As a postdoctoral researcher, your role can be diverse and multifaceted. Although responsibilities may vary depending on the field, common tasks include:

  • Conducting research: performing advanced research aligned with the project's objectives.
  • Disseminating findings: publishing results in academic journals, presenting at conferences, and engaging with the wider academic community.
  • Teaching and mentoring: some postdocs involve teaching undergraduate students or supervising postgraduate students.
  • Grant and funding applications: assisting in applying for research grants and other funding opportunities.

How long is a postdoc?

The duration of postdoctoral positions can vary widely, typically ranging from six months to three years. These may be extended if additional funding is secured. Many PhD graduates complete several postdoc positions before securing a permanent academic role.

How to get a postdoc position

Applying for a postdoc is similar to job hunting. You’ll need an academic CV, a cover letter, and references. Some applications might require a research proposal or a statement of research intent if the role allows for individual research projects. Here are key steps to follow:

  • Check eligibility: verify that you meet the specific criteria for each postdoc position, which typically requires a completed PhD.
  • Prepare your application: tailor your CV and cover letter to highlight relevant experience and skills.
  • Submit your application: follow outlined procedures for submission, ensuring deadlines are met.
  • Where to find postdoctoral positions

    There are many places where you can find postdoctoral positions. Universities and research institutes typically advertise internally as well as externally. Make sure you’re signed up for emails from relevant career hubs. There are also many independent websites specialising in job postings for academics, such as FindAPostdoc. Additionally, you may find positions on popular career websites like LinkedIn.

    Some aspiring postdoctoral researchers also hear about positions ‘through the grape vine’. Networking is a prominent part of being an academic and so attending conferences can be a great way to keep in touch with upcoming research projects.

What is the next step after a postdoc?

You're probably wondering what the career trajectory looks like after completing a postdoc. Here are a few avenues:

  • Academia: many aspire to secure permanent academic roles such as lecturers or professors. This often requires completing multiple postdocs and building a strong academic record.
  • Fellowships: prestigious fellowships offer greater research independence and can be a significant career milestone.
  • Industry: transitioning to industry roles is also a viable path. The skills acquired during a postdoc can be valuable in private research sectors, healthcare, and technology companies.

Is a postdoc right for you?

Completing a postdoc can be a rewarding experience, offering valuable research opportunities and professional growth. Whether you aim to secure an academic position or move into industry, a postdoc can provide the skills, network, and expertise needed to advance your career.
