Who Has the Highest H-Index Among Scientists?

World Highly Cited Researchers Citation Rankings 2025

The Citation Rankings (Highly Cited Researchers) provide a unique platform to highlight the most cited and influential scientists across a wide range of disciplines. Covering 197 main and sub-disciplines, including the Art and Humanities Citation Rankings and Social Sciences and Humanities Citation Rankings, these rankings showcase academic excellence on a global scale.

This exclusive service by AD Scientific Index adopts a meticulous approach to citation rankings, ensuring fair and balanced representation. Notably, it excludes data from CERN and other statistical sources that disproportionately favor certain researchers. This adjustment is particularly crucial in fields such as social sciences and humanities, where researchers often face challenges in competing with those involved in multi-author publications and CERN collaborations.

Why Citation Rankings Matter

Citation rankings not only highlight research impact but also address challenges within the academic community. By analyzing citation data, these rankings help uncover unethical practices such as:

• Honorary authorship
• Citation cartels
• Excessive self-citation
• Other forms of misconduct

This transparency promotes accountability, ensuring that academic recognition is truly merit-based.
