During my PhD I have developed two different research projects in parallel. This was not planned from the beginning, it just happened this way. I am sure each of these could be presented as a PhD and I am thinking on the possibility of presenting both, one after the other one. Would that make sense?

I had a quick talk with my Professor although I didn't ask him about this option because I had the fear he would find it a bit arrogant. So first of all, I wanted to get to know if it is meaningful.

Thanks in advance

    You cannot obtain two Ph.D. degrees by carrying out two research projects in the same field, albeit in different topics – it just does not make sense. Ph.D. is a per-discipline degree or a per-field-of-study degree (the latter applies to interdisciplinary fields). Commented Oct 11, 2015 at 10:16

    I am not sure you understand what a PhD is. In many disciplines (e.g. CS) you need multiple good publications (>3) to obtain a PhD. Thus, you have to work on many different projects (somewhat related but not entirely) to actually produce these publications.

  • Thanks for your reply. However I understand my question is substantially different from the previous threat on this topic. In that one, the person is asking if it is worthy to work in this direction as a future plan. In mine, I already have two fully finished projects and I'm wondering whether presenting them both as PhDs is a good idea. Commented Oct 11, 2015 at 14:03

    In addition to the earlier comments, I don't see how you can submit two PhD theses when you are only registered on one PhD course.

There are many more interesting groups you could present the second project to than a doctoral committee.

Go forth and publish.

  • Thanks for the reply. Sorry, what kind of groups do you mean? Both projects are done at a university. Commented Oct 11, 2015 at 14:00
