The Top 100 scientists are ranked based on total H-index scores at the global, regional, national, and institutional levels. Rankings cover 10 regions, 13 main fields, and 221 subfields. Subject-field rankings (world, region, country, and university levels) are currently in Beta and updated in near real-time.
Note: Researchers classified as “others” (1,123,399 profiles whose fields are undetermined or not yet edited) are excluded from subject and regional rankings. These rankings will dynamically evolve as the “others” profiles are reviewed and properly categorized.
Recognizing excellence across 10 regions, 13 fields, and 221 subfields — Explore the Top 100 today.
