Built from the index, not written by the researcher. It shows published papers in OpenAgData whose byline carries this ORCID iD, or that the ORCID record itself lists, which is usually a part of someone's work, not all of it. Names, affiliations and funding acknowledgements are as the papers print them, and a funder thanked in a paper is not necessarily an award the researcher held. Citation counts are OpenAlex's.
