Notice: Please note that the subject field rankings for the world, region, country, and university are in the Beta Version due to the exclusion of profiles classified under 'Others' (873.864 scientists whose branches have not been determined or updated). These rankings will adjust as profiles are updated.
Top %3 Indicator: The 'Top 3%' label indicates that a scientist ranks within the top 3% of all scientists in the AD Scientific Index for their specific subject field at the institutional, country, or world level.
Reporting Inappropriate Profiles: To report inappropriate, inaccurate, or unethical profiles, including deceased scientists or profiles that require deletion, please contact [email protected].
