Highly Cited Researchers 2.343 Scientists Citation Rankings - 2025
The Citation Rankings (Highly Cited Researchers) list highlights the most cited and influential researchers across a vast range of scientific fields, covering 211 main and sub-disciplines, including the Art and Humanities Citation Rankings and Social Sciences and Humanities Citation Rankings. This service, offered exclusively and with real-time updates by AD Scientific Index, aims to provide a balanced and dynamic perspective by excluding data from CERN and other statistical sources that disproportionately favor certain researchers — particularly in the social sciences and humanities. This real-time methodology addresses the unfair advantage researchers with multi-author publications and CERN involvement hold over others, ensuring a more equitable evaluation. Furthermore, real-time citation rankings help uncover rule violations and unethical practices within the research community by continuously monitoring citation behavior.
