Subject Field Ranking Notice: Please be aware that the subject field rankings for the world, region, country, and university are currently in Beta Version. This is due to the exclusion of profiles categorized under the 'Others' field, which includes (829.221 scientists whose branches have not yet been determined or edited. As these profiles are updated, the rankings will adjust accordingly.
Top %3 Indicator: The "Top %3" designation indicates that a scientist ranks within the top 3% of all scientists in the AD Scientific Index in their specific subject field, either at the institution, country, or world level.
Reporting Inappropriate Profiles: If you encounter inappropriate, inaccurate, or unethical profiles, a deceased scientist, or any other situation that warrants deletion of a profile, please report it to [email protected]. In accordance with our Data Privacy Policy, should you wish to have your personal information removed, you can request this by emailing [email protected]. Your data will be deleted within a maximum of 5 business days.
