Five researchers from Royan Institute, who are ranked among the top 2% of scientists worldwide, have been recognized by Stanford University’s website.
According to the Public Relations and International Affairs of Royan Institute, the Top 2% list of the world’s leading scientists, introduced by Stanford University, is a prestigious scientific ranking that identifies and honors the most influential researchers across various subject areas. Among these, five researchers from Royan Institute have been included in the list of the top 2% of scientists worldwide.
This ranking, based on data from Elsevier in collaboration with the Scopus database, is a powerful tool for identifying the world’s leading scientists. The top 2% citation-based ranking strives to identify researchers who have made significant contributions to their respective fields through a standardized approach. The list is created based on indicators such as citations, the h-index, co-authorship, and normalized citation counts.
The Top 2% citation-based researchers list is updated annually, with data categorized into two groups: Career Long Data and Single Year Impacts. The Career Long Data category reflects a researcher’s overall performance from the start of their career, including their recent achievements, while the Single Year Impacts category focuses solely on the researcher’s performance in the year 2024.

Key Indicators of the Top 2% Researchers List:
The primary criterion for this list is the normalized citation count. The normalized citation index used in this list is called C-Score, which is derived from several bibliometric indicators: total citations, the h-index, and the number of citations received by the researcher, excluding self-citations.
The main research domains and their subdomains are categorized as follows: The list is divided into 22 major subject areas and 174 sub-disciplines. Only those researchers who are placed within a sub-discipline are included in the top 2% category.
Stanford University’s Top 2% list is a recognition of scientific excellence and impact. By aggregating data across various scientific fields and offering a fair, normalized approach, this list not only celebrates individual achievements but also emphasizes the importance of impactful research in advancing knowledge.
