I am in a situation similar to that of this question where I did some work with a former employer, I changed fields, and now something related to that work is in the process of being published. Initial submission of the work was during my time with my former employer, but revisions are happening after leaving. The paper is a single author paper. Based on the responses to that question, it seems like I should be using my former employer as my affiliation, but I have a few difference in my situation that I would like to clarify.

  1. The work in question is a discussion paper which was solicited from me by a journal. As such, I gained the expertise necessary to write the paper working for my former employer, but the paper itself was written in my personal time so neither organization directly funded any of the work in the paper. However I would not have been requested to write the paper if not for my work with my former employer.
  2. If I do decide to use my former employer as my affiliation, what should my contact email be? I would rather not use a personal email, but I don't have access to the work email from my former employer, and it seems weird for my affiliation to be Company A, but my email to be [email protected].

In case it affects your response, the paper is in the field of quantitative forecasting and specifically on the use of machine learning for forecasting, which is what I did for my former employer. I now work using machine learning for video processing on medical devices.

  • If you look at the posts with tag affiliation you will probably find a good answer to your question. There have been several.

  • @Buffy Do you have a specific post in mind? I looked around in that tag for a while and I found one that was pretty similar, which I linked, but I couldn't find anything which addressed the two specific points I have listed below. For example, most posts where work is done in personal time, the work is also unrelated to the work with their employer. I couldn't find anything about email contacts.

  • The answer to this question depends on the customs in your field of study; different fields have different customs. (I have added an item to the "Academia varies more than you think" answer on "Welcome to Academia.SE" to say this.) Commented Feb 11, 2019 at 0:17
  • @AlexanderWoo I updated to include the field of study if that helps. If not, how do I find out the field specific answer?

  • @Barker - you can try asking senior people in your field who are likely to have encountered this situation (it's not that rare) before and thought about the issue. If you don't know anyone, the editor of the journal to which you are submitting the paper is a good option. Commented Feb 11, 2019 at 19:24

If you have the opportunity to be clear (that is, some limited online form doesn't prevent it) explain the transition "Jon Barker, formerly of Acme Corp, now with Zypppy Inc. [email protected]". Or something similar.

The reason for the email is so that people can contact you, so use the current one even if it seems weird. Using an obsolete mail does no one any good.

If the former employer/institution contributed funds to the project it is usually good etiquette to indicate that you were associated with them then. But for identification purposes, your current affiliation is more valuable. But if it is a paper with multiple authors, some still at Acme, then it is less important to list an old affiliation (my opinion only).

There may even be reasons that you must not imply an affiliation that no longer exists, but that is fairly rare. If you can only give a single affiliation, it is probably best in most cases to list your current one. I suspect such a rule has many possible exceptions, but I'd suggest thinking about why you think you have an exceptional case.
