My colleague and I are both PhD students (My colleague started about 8 months after me) from the same research group (and share the same PhD supervisor) in a UK university. We were collaborating on a research project with a Prof. 'X' from another university in the EU.

Early on in the project (March 2017), over a phone call, Prof 'X' requested my colleague to provide them with a 1-page project summary to support a small grant application. My colleague and I worked on this at my colleagues work desk for a single afternoon (about 2 hours) to produce this document. Both of us thought out aloud, iterated the words & phrases a few times to write and polish this document. Since we were working on the colleague's computer, after writing we just opened the email client on that machine and sent the 1-page doc as an email attachment to Prof 'X'.

The document itself contains only 5 paragraphs of pure text. It does not contain any title/authorship or any other information whatsoever (such as header/footer). My colleague signed the email as "Best Regards, A & B". where "A" is me and "B" is my colleague. Later on, the colleague forwarded the same email (with the attachment) to our common PhD supervisor (as an FYI).

As we proceeded further into the project, the involvement of my colleague and mine became intricately interwoven. It soon very became hard for our common PhD supervisor to separate out individual contributions. There was a huge authorship dispute of the resulting paper (manuscript) which lasted 8 months but eventually got resolved, nevertheless leaving my colleague and me in not good terms.

Since this project was important to our respective PhD theses, it became crucial to clearly identify who contributed what. As part of this forensic examination, both of us gave our evidences to our common PhD supervisor, who apportioned the contributions suitably on a high-level basis. It was decided that both our theses shall have a suitably detailed "attribution of content" section for this relevant chapter, and the contents of the scientific reporting shall be minutely scrutinised by our common supervisor to prevent any allegations in the future.

Present Situation

I recently passed my PhD viva. Examiners were happy and the outcome was to submit minor corrections in 90 days time which were to be checked and approved by them. However, just before leaving for Christmas holidays, my PhD supervisor ran my submitted version of thesis in turnitin (against all relevant docs for this project) and found that I had large chunks of text (2 lightly modified paragraphs) copied verbatim from the email attachment. Our PhD advisor then inquired with my colleague about this, who insisted that the document was entirely written by him albeit with intellectual inputs from me . Therefore, our PhD supervisor asked me to re-write these 2 paragraphs and said they had no choice but to inform the internal examiner about this.

I am really worried. I copied and modified the 2 paragraphs because I thought I was entitled to reuse these words from that email attachment. Did I do something egregious? Am I in deep trouble? I am happy to re-write these 2 paragraphs from scratch, but I cannot afford to lose a degree I worked for 4 years for something little like this. What are my options if I am accused of plagiarism?

    A very strange situation from beginning. I think your supervisor want to prevent another 8 months discussion on who did/wrote what..... cannot be plagiarism nor self plagiarism. In the worst case your colleague could argue but I don't see why unless your thesis is as short as that attachment was :)

    The email included both of your names, so the document (which itself mentioned no authors) was prima facie authored by you both. At least there's no reason why it should have been authored by your colleague alone. The fact that your colleague sent the email from his mail account but felt the need to sign with both your names even makes it plausible that he then thought of you both as authors. Why else would he have included your name as well? Commented Dec 23, 2018 at 0:48
  • What you told us (that the document in question was written by both of you and you don't remember who wrote what) is a strong argument in your defense, and you should explicitly tell it to your supervisor and everyone else involved. If you silently agree to make changes to your thesis, you'll be admitting that you did something wrong, which you did not.

1 Answer 1


Not knowing the policies of your university, nor of your advisor, it is hard to be definitive in an answer here. However, I'll suggest that you do two things. One is to re-write the paragraphs as you seem willing to do, but also contest the characterization that the original wasn't joint work with you as an equal contributor. If necessary (and possible) make your claim formally, in writing. You don't need to accuse the other student of misconduct, but you need to be clear that you worked jointly. The other student may just misremember the interaction, of course. Best if you have preserved some evidence of course.

I would also try to get the professor to stand up for you with the internal examiner.

If you are reporting accurately, then nothing you did was wrong unless the attachment was somehow published and you failed to cite it. That would be self plagiarism and is in a different category than ordinary plagiarism.

My personal opinion about self plagiarism is that you can copy and include your own unpublished work without citation, but need to cite earlier work of your own rather than just copying. That is to permit readers to trace back and find the complete context of a work.

However, there is one aspect I'm unclear about. If the attachment wasn't ever published, how did turnitin even find it for analysis? If it was published, perhaps without your knowledge, that raises other issues.

    I shall further explain here. Of course, I shall re-write the 2 paragraphs, but the internal examiner has already been alerted to this and I may have to defend any accusations of plagiarism. I have told my supervisor that we worked jointly, but there is of course no proof of this. Can the last line of email ("Best Regards, A & B" where "A" is my name can be considered as proof of this joint work? Turnitin can run against custom sources. As part of apportionment of work for our respective theses, our supervisor had submitted docs such as this email attachment & the journal article to turnitin Commented Dec 22, 2018 at 14:03

    +1 good response - also, "Best Regards, A & B" where "A" is you - if the email was sent from B's account, definitely acts as a proof of joint authorship. Contest emphatically on grounds that you assumed to the best of your knowledge that piece of mail not having been published. Commented Dec 23, 2018 at 0:00
