Stanford University has recently released the list of the World’s Top 2% Scientists 2022, which represents the top 2% of the most-cited scientists in various disciplines. The list included 100,000 top scientists based on their career-long citation impact (until the end of 2021) and single-year citation impact (2021). Scientists are classified into 22 scientific fields and 174 sub-fields. The rankings are calculated based on standardized information of citations, h-index, co-authorship-adjusted hm-index, citations to papers in different authorship positions, and a composite indicator.
