Lecturers and researchers from the Faculty of Mathematics and Natural Sciences, University of Indonesia (UI), have once again achieved extraordinary achievements on the international stage. Prof. Dr. rer. nat. Rosari Saleh, Prof. Dr. Yoki Yulizar, Prof. Dr. Ivandini Tribidasari Anggraningrum, Dr. Dipo Aldila, M.Si., and Dr. Zuherman Rustam have all made it into the World’s Top 2% Ranking of Scientists 2022.

The list of the world’s best researchers was officially released on October 10, 2022. As an annual publication, the World’s Top 2% Scientists 2022 is the fourth edition. Elsevier previously published the first edition in July 2019, the second in October 2020, and the third in October 2021.

The Top 2% Scientists in the World assessment was conducted by Professor John P.A. Ioannidis, M.D., Ph.D. of Stanford University; Jeroen Baas of Elsevier; and Kevin Boyack of SciTech Strategies, published in the fourth edition of the “Updated Science-wide Author Databases of Standardized Citation Indicators.”

Special criteria are established to identify the best researchers on an international scale. Stanford University and Elsevier created a database of top-cited scientists that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations for papers in different authorship positions, and a composite indicator (c-score).

Scientists included in this assessment are classified into 22 scientific fields and 176 subfields. Selection is based on the top 100,000 scientists based on c-score (with and without self-citations) or a ranking of 2% or higher in a specific subfield. A total of 195,605 scientists are included in the career-long database, and 200,409 scientists are included in the single recent-year dataset.
