TL;DR

• Corresponding author manages all journal communication on behalf of co-authors.

• Only one person holds this role per submission, not multiple.

• Responsibility includes submission, revisions, proofs, and post-publication queries.

• Corresponding authorship is separate from first authorship or credit order.

• Student researchers can be corresponding authors on their own papers.

You have finished your research paper. You are ready to submit. Then the journal's submission portal asks: who is the corresponding author? If you are working alone, the answer is straightforward. If you are working with collaborators, the question gets complicated fast.

Many student researchers treat this field as an administrative detail and fill it in without thinking. That is a mistake. The corresponding author role carries specific responsibilities that last well beyond the submission date. Getting it wrong can create confusion, delay your publication, or create disputes with co-authors later.

Understanding what a corresponding author actually does, and who should take on that role, is one of the most practical things you can learn before you submit your first paper.

What Is a Corresponding Author?

A corresponding author is the person on a research paper who handles all official communication with the journal. This includes submitting the manuscript, responding to peer reviewer comments, approving proofs before publication, and answering any questions from editors or readers after the paper is published. Every journal requires exactly one corresponding author per submission.

The word "corresponding" refers to correspondence, meaning letters and communication. Before online submission systems existed, journals would mail physical letters to one designated author. That author was responsible for keeping the rest of the team informed. The name has stayed even though the communication is now digital.

Journals publish the corresponding author's email address alongside the paper. This is the contact point for anyone who wants to request data, ask about methodology, or flag an error. That visibility is part of the responsibility. If a correction is ever needed after publication, the journal will contact the corresponding author first.

How Is the Corresponding Author Different from the First Author?

First authorship and corresponding authorship are separate roles that sometimes overlap but often do not. First authorship reflects who made the largest intellectual contribution to the research. Corresponding authorship reflects who is taking administrative responsibility for the paper's journey through publication.

In many student projects, the student who did the most work is listed first and also serves as the corresponding author. This is common and entirely acceptable. But in larger research teams, a senior researcher or supervisor might take the corresponding author role while a student or junior researcher is listed first. This arrangement acknowledges that the supervisor has more experience navigating journal communication.

Understanding what is authorship order and how it is decided will help you see how these two roles fit into the broader picture of credit and responsibility on a shared paper.

Some journals, particularly in the life sciences, use a symbol or footnote to indicate when the first author and corresponding author are the same person. Others simply list the corresponding author's email at the bottom of the paper without any special notation.

What Does a Corresponding Author Actually Do?

The corresponding author's responsibilities begin before submission and continue after publication. Here is the full sequence of what that role involves:

1. Pre-submission: Confirm that all co-authors have approved the final manuscript and agreed to the submission. According to the Committee on Publication Ethics (COPE), corresponding authors are responsible for ensuring all listed authors meet authorship criteria before the paper is submitted.

2. Submission: Complete the journal's online submission form, upload the manuscript and any supplementary files, declare any conflicts of interest, and sign any required agreements on behalf of the author group.

3. Peer review: Receive the editor's decision and reviewer comments, share them with co-authors, coordinate the group's response, and submit the revised manuscript along with a formal author response letter.

4. Proofing: Review the typeset proof of the paper before it goes live, check for formatting errors, and approve the final version within the journal's deadline.

5. Post-publication: Respond to any reader queries, handle requests for data or materials, and manage any corrections or retractions if errors are discovered later.

That is a significant commitment. It is not just about clicking submit. The corresponding author is the paper's point of contact for its entire published life.

If you are preparing your first submission and want structured support navigating this process, joining the Publication Compass waitlist gives you early access to a platform built specifically to guide student researchers through each of these stages.

Can a Student Be a Corresponding Author?

Yes. There is no rule that prevents a student from serving as the corresponding author on their own paper. Many journals actively welcome student-led submissions, and being the corresponding author on a published paper is a meaningful credential for university applications and future research opportunities.

The practical consideration is whether you will still have access to the email address you use for the submission in the years after publication. Journals sometimes contact corresponding authors months or years later with questions about the research. If you use a school email that expires when you graduate, you may miss those communications.

A personal email address that you control long-term is a better choice for the corresponding author field. Some researchers also use a university email if they are enrolled for several more years, but it is worth thinking about continuity before you submit.

If you are working without a faculty supervisor, the question of who takes the corresponding author role is entirely yours to decide. Understanding the full scope of publishing without a professor co-author as an undergrad will help you prepare for what that independence actually involves.

What Journals Expect from the Corresponding Author at Submission

Different journals have slightly different requirements, but most expect the same core set of declarations from the corresponding author at the point of submission. Being unprepared for these can slow down your submission or cause it to be returned before review.

Most journals ask the corresponding author to confirm the following at submission:

1. All named authors have seen and approved the manuscript in its submitted form.

2. The paper is not under consideration at any other journal simultaneously.

3. Any conflicts of interest, including funding sources, have been disclosed.

4. Any ethical approvals required for the research (such as for human subjects research) have been obtained and documented.

5. The corresponding author has the authority to act on behalf of all co-authors during the review process.

Journals like PLOS ONE and Frontiers in Education, both of which publish student and early-career research, make these requirements explicit in their submission guidelines. Reading those guidelines before you begin filling out the submission form will save you significant time.

If your paper goes through peer review and revisions, the corresponding author is also the person who writes and submits the author response letter. Knowing how to write that document clearly and professionally is a skill worth preparing for. A detailed walkthrough of the author response letter template for revisions can help you understand what reviewers and editors expect to see.

Who Should Be the Corresponding Author on a Collaborative Paper?

On a paper with multiple authors, choosing the corresponding author should be a deliberate conversation, not an afterthought. The right person is usually the one who is most available, most organised, and most committed to seeing the paper through to publication.

Here are the factors worth discussing with your co-authors before you decide:

1. Availability: Peer review timelines are unpredictable. The corresponding author needs to be able to respond to editor requests within a few days, sometimes within 48 hours. If one co-author is about to start exams or a new job, they may not be the right choice.

2. Experience: If one author has published before and understands the submission and revision process, it often makes sense for them to handle the correspondence. Less experienced authors can still be listed first for credit purposes.

3. Stable contact information: As noted above, the corresponding author's email appears on the published paper permanently. Choose someone whose contact details are unlikely to change.

4. Agreement from all co-authors: COPE guidance is clear that all authors should agree on who the corresponding author will be before submission. Do not assign this role to someone without their explicit consent.

If you are weighing up whether to write a paper alone or with collaborators, the question of corresponding authorship is one of several practical differences between the two approaches. The comparison between single author vs co-authored papers for students covers those trade-offs in detail.

What Happens After the Paper Is Published?

The corresponding author's job does not end when the paper goes live. After publication, the corresponding author remains the official contact for that paper indefinitely. Other researchers who want to replicate the study, request raw data, or ask about methodology will email the address listed on the paper.

Journals may also reach out if they discover an error in the published version, if a reader raises a concern about the research, or if the paper is cited in a way that requires clarification. In rare cases, if a paper needs to be corrected or retracted, the corresponding author is the first person the journal contacts.

Understanding what happens after your paper is accepted gives you a fuller picture of the post-acceptance process, including proofing, publication timelines, and what to expect once your work is publicly available.

Publication Compass is a platform designed to help student researchers navigate the full submission process, from identifying the right journal to preparing for peer review. It does not replace the corresponding author's responsibilities, but it gives you the structure and guidance to carry them out with confidence.

Frequently Asked Questions

Can there be two corresponding authors on one paper?

Most journals allow only one corresponding author per submission. A small number of journals permit co-corresponding authorship in exceptional cases, typically for large multi-institution collaborations. Check the specific journal's author guidelines before assuming this is possible. When in doubt, designate one person and note the other's contributions in the acknowledgements section.

Does the corresponding author have to be the most senior person on the paper?

No. Seniority does not determine who serves as corresponding author. The role goes to whoever is best placed to manage journal communication reliably and responsibly. Junior researchers, including students, can and do serve as corresponding authors on papers they led. What matters is availability, organisation, and a stable email address.

What is a corresponding author's responsibility if a co-author later disputes their inclusion?

If an authorship dispute arises after submission, the corresponding author is the journal's primary contact for resolving it. COPE provides detailed guidance for editors handling authorship disputes, and journals will typically ask the corresponding author to facilitate a resolution among the team. This is one reason why getting written agreement from all co-authors before submission matters.

Is the corresponding author always listed first in the author list?

No. Author order and corresponding authorship are independent. The corresponding author can appear anywhere in the author list, first, last, or in the middle. Journals typically indicate who the corresponding author is through a footnote symbol or by publishing their email address separately from the author list itself.

What should I do if I used a school email as my corresponding author address and it has expired?

Contact the journal directly and request a corresponding author email update. Most journals have a process for this. You will usually need to provide proof of identity and confirm the change with your co-authors. Act quickly if you notice the issue, because missed post-publication correspondence can create problems if a correction or query arises later.

Getting This Right Before You Submit

The corresponding author role is one of the most overlooked parts of academic publishing for first-time researchers. It is not just a field to fill in. It is a commitment to manage your paper's relationship with the journal from submission through to its entire published life. Choosing the right person, using the right contact details, and understanding what the role involves will make your submission smoother and your post-publication experience far less stressful.

If you are preparing to submit your first paper and want a clearer path through the process, the Publication Compass blog covers every stage of academic publishing for student researchers, from understanding peer review to choosing the right journal for your work.
