Most authors spend weeks on their manuscript and ten minutes on their biography, yet the biography is often the first thing an editor, reviewer, or reader learns about who wrote the paper. A good author biography is short, factual, and useful: it tells the reader what you do, where you do it, and why you are qualified to write on this topic, without turning into a CV or a piece of self-promotion.
This guide explains what journals actually ask for, how long a biography should be in different contexts, and a simple structure you can reuse for every submission. It also covers the mistakes that make biographies look careless, such as outdated posts, inflated claims, and a list of publications nobody asked for.
An author biography, sometimes called an author bio or contributor note, is a short paragraph about the author that appears alongside a published article, on a journal's website, or in a conference programme. Journals use it to introduce authors to readers, and readers use it to judge context: is this author a doctoral student writing a first paper, a clinician reporting from practice, or a senior researcher summarising a long programme of work?
It is not the same as a CV. A CV lists everything; a biography selects only what helps the reader understand this paper. It is also not the same as an acknowledgements section, which thanks funders and helpers. Keep the biography focused on identity and expertise: your name, your current role and institution, your research interests, and, where relevant, one or two publications or achievements directly connected to the topic. Everything else can stay on your institutional profile.
Editors check biographies for accuracy and consistency before anything else. Your name should match the name on the manuscript and on your other records, your affiliation should be the institution where the work was done or where you are now based, and your role should be stated plainly. If you have moved since the work was done, many journals allow a present address to be added separately, so tell the editorial office rather than quietly replacing the original affiliation.
Editors also look for claims they can stand behind. A biography that says you are a professor when you are a lecturer, or that describes a paper as widely cited when it has barely been read, creates a problem the journal must fix. Write only what you can support, and let the work speak for the rest. If you are an early-career researcher, say so honestly: journals publish first papers all the time, and a clear, modest biography inspires more confidence than an inflated one. For the wider submission journey, see our guide on how to publish a research paper.
Consistency across co-authors matters too. When a paper has several authors, editors notice when one biography is a paragraph and another is a single line, or when affiliations follow different formats. Agree a shared format before submission, and check that every author's details match the manuscript's title page.
A reliable structure has four parts, in this order. First, your current role and institution, for example a lecturer in veterinary medicine at a named university. Second, your research interests, in one sentence, connected to the paper's topic. Third, a brief note of relevant experience or selected work, such as a previous study, a thesis, or a practical role. Fourth, an identifier or contact route, most usefully your ORCID iD, which lets readers find your other work without ambiguity about similar names.
Here is that structure in action, as a pattern rather than a real person: a lecturer in animal sciences whose research covers smallholder dairy production, who previously studied feeding practices on family farms, and who lists an ORCID iD for a full publication record. Each sentence earns its place because it helps the reader place the paper. If a sentence does not help the reader understand this article, cut it, however proud of it you are.
Length depends on where the biography will appear, and the journal's author guidelines are the final authority. A short biography of about fifty words suits a journal that prints a one-line contributor note beside each article. A standard biography of about one hundred words suits most journal websites and article pages. A longer biography of about two hundred words suits a book chapter, an invited review, or a conference keynote, where the reader is expected to want more background.
The practical rule is to write the one-hundred-word version first, then cut or expand it as the guidelines require. Keep a master version saved with your submission files, and update it whenever your role, institution, or research focus changes. Sending the same biography to five journals over three years without checking it is how out-of-date posts and long-finished projects end up in print. Check it against the manuscript before every submission, just as you check the title and the abstract.
Special issues and invited pieces sometimes ask for a longer biography than a standard article, because the editor wants readers to understand why you were invited. If you are asked for a longer version, expand the middle of the biography, on expertise and relevant work, rather than adding a list of posts. The reader's question is still the same: why is this author qualified to write this piece?
If you publish under more than one name form, for example a full name in one country and an initialled form in another, choose one form for the biography and record the others on your ORCID record. Journals and databases match authors far more reliably when the biography, the manuscript title page, and the ORCID record all use the same professional name.
A journal biography, a conference biography, and a book biography differ in emphasis even when they describe the same person. A journal biography stresses the expertise behind this paper. A conference biography stresses what the audience will hear and why the speaker is qualified to give it. A book biography may range more widely, because the reader is committing to a whole book rather than one article. The table below summarises the differences.
| Context | Usual length | Main emphasis | Include |
|---|---|---|---|
| Journal article | 50 to 100 words | Expertise behind this paper | Role, institution, interests, ORCID iD |
| Conference programme | 50 to 75 words | Why this speaker, this talk | Role, topic, one notable work |
| Book chapter | 150 to 200 words | Wider background | Career path, books, major projects |
| University profile page | 100 to 200 words | Full professional picture | Teaching, supervision, full publication list link |
The most common mistake is turning the biography into a CV, listing every post, prize, and paper since graduation. Readers stop reading, and editors cut it anyway. A second mistake is hype: words such as world-leading, renowned, or groundbreaking in your own biography sound like advertising, and reviewers notice. Let other people describe your work that way, if they choose to, and keep your own account factual.
A third mistake is inconsistency of person and tense. Some journals prefer third person, some accept first person, so follow the journal's house style and be consistent within the paragraph. A fourth mistake is leaving in details that are no longer true: a former post, a finished project described as current, or an email address you no longer check. Finally, never include personal details that do not belong in a professional publication, such as family information or private contact details. A biography is a professional introduction, not a personal profile.
Do not put a personal email address in your biography unless the journal specifically asks for one. Readers normally contact authors through the corresponding author details on the article page, and a personal address printed in a biography will attract spam for as long as the article is online. Keep contact routes in the places designed for them.
Be selective about which publications you mention. A biography that lists work in venues a reader cannot verify, or that describes every item as a major contribution, weakens trust instead of building it. Mention the one or two items most relevant to this paper, and let your profile record carry the full list.
Run through this checklist on the final version, not on an early draft. Is your name spelled exactly as it appears on the manuscript? Is your affiliation current and correct? Does the biography mention the expertise behind this paper, rather than your whole career? Is every claim in it something you could support if asked? Is it written in the person and tone the journal asks for, and is it within the word limit the guidelines set?
If you can answer yes to each question, the biography is ready. Save it with your submission files, add your ORCID iD if you have one, and read our companion guide on how to create an ORCID profile if you have not set one up yet. A short, accurate biography will never make a weak paper strong, but it does something almost as valuable: it lets the reader trust the author before reading the first page.
Finally, compare the biography with your ORCID record before you submit. If the record lists a different institution, a different name form, or works the biography does not mention, a reader who follows the link will be confused. A two-minute comparison keeps the two introductions telling the same story.
A biography is not a document you write once and forget. Roles change, research interests shift, and a project described as current becomes history. Set a routine: review your master biography whenever you change post, complete a qualification, or publish in a new area, and update the version held by each journal only through the proper channels, since published biographies are part of the published record.
Name changes deserve particular care. If you change your name, tell journals and update your ORCID record so that your earlier and later work remain connected. Consistency matters more than form: use the same professional name across manuscripts, profiles, and conference programmes, and record other name forms on your ORCID record so that databases can match them.
As your career grows, resist the urge to let the biography grow with it at the same rate. A senior researcher with twenty publications does not need twenty lines of biography; readers still want the same four things, namely role, institution, interests, and a route to the full record. Select the two or three achievements most relevant to the paper in hand, and let your profile page carry the rest.
Keep a master file with three versions: a fifty-word note, a one-hundred-word standard version, and a two-hundred-word long version. Store them with your submission templates, date the file, and note which version you sent to each journal. That small habit prevents the common embarrassment of a biography that names a post you left two years ago.
Ready to publish your study? Submit your manuscript to Global Academic Publishers and follow the journal's author guidelines for the Global Journal of Veterinary and Animal Sciences.
Most journals want between 50 and 100 words. Always check the journal's author guidelines first, because the required length and style vary, and write a 100-word version you can cut or expand as needed.
Follow the journal's house style. Many journals use third person for biographies, while some accept first person. Whichever you use, be consistent throughout the paragraph.
Your current role and institution, your research interests, and the work behind this paper, such as your thesis or a recent project. Honesty about your stage inspires more confidence than inflated claims.
It is not always required, but it is very useful. An ORCID iD distinguishes you from researchers with similar names and lets readers find your other work reliably.
You can reuse a master version, but check it before every submission. Update your role, institution, and research focus when they change, and adjust length and style to each journal's guidelines.
Leave out your full CV, personal details, private contact information, and any claim you cannot support. A biography is a short professional introduction, not a complete career history.
