The analysis was performed by a team from Stanford University, USA using Scopus data provided by Elsevier. The four professors are among 38 scientists based in Sri Lanka who were included in the list. 

Scientists are classified into 22 scientific fields and 176 sub-fields. Field-specific and subfield-specific percentiles are provided for all scientists with at least 5 papers. Single recent year data pertain to citations received during the calendar year 2021. The selection was based on the top 100,000 scientists by c-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field. The calculation was performed using all Scopus author profiles as of the 1st of September 2022.
