It is not uncommon to move from one place to the other as fa as working institutions is concerned. This could occurs due to many factors. Someone worked for three years at MIT, and at Harvard University currently. His/her affiliation is Harvard University at present.
If he/she want to publish a research work done at previous work institution (MIT), which institution is used as affiliation for the researchers to be written in title page of the research work? The current or previous institution?
Thank you in advance!
