According to the Research Division of the Pasteur Institute of Iran, four of the institute’s researchers—Azam Bolhassani, Mehdi Farokhi, Mohammad Ali Shokrgozar, and Mojgan Sheikhpour—are included in the single-year citation impact list in the 2026 update of the database commonly known as the “World’s Top 2% Scientists” list. Developed by John P. A. Ioannidis and colleagues using Scopus data, the database assesses researchers’ citation impact through standardized bibliometric indicators. These include citation counts, the h-index, the co-authorship-adjusted h_m-index, and a composite citation score that incorporates authorship positions. The approach emphasizes citation impact rather than publication counts alone. The 2026 update was released in October 2026. Its single-year list evaluates citations received during 2025. The four researchers’ rankings are presented below.

Rankings are based on the composite citation score excluding self-citations.
