Charlotte Mueller points out in “Migration and Knowledge Transfer” (NVVN blog) that “migrants can be knowledge senders and knowledge receivers simultaneously, in their country of destination as well as in their country of origin.” Knowledge transfer and human migration can both be “circular.”
"Migration" is not a stable, preexisting category but rather a product of societal processes that shape what the term comprises. We must take these entanglements with the past into account in our present-day research.
