Clarivate Highly Cited Researchers 2025

Of the world’s population of scientists and social scientists, Highly Cited Researchers are 1 in 1,000

Highly Cited Researchers demonstrate significant and broad influence in their field(s) of research. Each researcher selected has authored multiple Highly Cited Papers which rank in the top 1% by citations for their field(s) and publication year in the Web of Science Core Collection over the past eleven years. However, citation activity is not the sole selection indicator. This list, based on citation data, is then refined using other quantitative metrics, as well as qualitative analysis and expert judgment.
