Changing my information in a published paper How can I change my position/title that was mistakenly written in a published paper?
If the paper has already been published, you can't. It's too late. Even if the print versions have not been printed, the electronic version will have been distributed, and it's not possible to issue a recall.
If the issue is severe enough you could publish a corrigendum/erratum, for which you'd have to ask the journal.
