To correct and update your Profile, you will have to submit change requests to Scopus. The changes will usually be completed within 2-4 weeks. Before you can submit any change request, you will have to create an account and sign in to Scopus. Then Scopus will know how to contact you for the changes you request.
You can set the preferred name, update your affiliation, merge Profiles, and edit the document list in your Scopus Author Profile by clicking "Edit author profile". The Scopus Author Feedback Wizard will show up and guide you in making corrections to your Profile.
Under the session of Profile actions, you can find other options, such as connecting to ORCID, setting alerts, and exporting the Profile to SciVal to conduct more analyses.
