Highly Cited Researchers have demonstrated 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™ over the past decade. However, citation activity is not the sole selection indicator. A preliminary list based on citation activity is then refined using qualitative analysis and expert judgement.
Of the world’s population of scientists and social scientists, Highly Cited Researchers™ are 1 in 1,000.
