World Top 100 Scientists 2025

Top 100 scientists can be ranked globally or specific to the following regions including Africa, Asia, Europe, North America, Latin America, Oceania, Arab League, ASEAN, EECA, and BRICS based on total H-index scores without any breakdown by subject areas. Top 100 rankings in the world, in a continent, or a region include standardized subjects areas of Agriculture & Forestry, Arts, Design and Architecture, Business & Management, Economics & Econometrics, Education, Engineering & Technology, History, Philosophy, Theology, Law/Law and Legal Studies, Medical and Health Sciences, Natural Sciences, Social Sciences, Art and Humanities Rankings and Social Sciences and Humanities Rankings BETA VERSION. Subject field rankings in world, region, country, and university are in Beta version and are subject to real-time updates, since the subject field “Others” (0 scientists profile whose branch cannot be determined, not yet edited or determined) is excluded. These rankings will dynamically evolve in real time as the “Others” profiles are revised and classified. Please note that. Subjects indicated as “ * others ” will not be included in the ranking by regions and subjects.
