Discrepancies with Author's name and identity can occur when:
A Researcher Identity would help to attribute all works to the correct author and avoid such discrepancies.
An ORCID is a persistent and unique researcher identity that would help distinguish you from other authors. This would lead to less ambiguity when attributing your work to your identity.
In NTU, it is mandated that you must have an ORCID.
There are other researcher identities and these can be consolidated in your ORCID profile.
Do note that these profiles can be consolidated in your ORCID profile.
