Understanding the Stanford/Elsevier Top 2% Scientists List
Developed jointly by Stanford University and Elsevier, this prestigious ranking employs a sophisticated methodology to identify global scientific leaders. The selection utilizes a composite indicator (c-score) that accounts for citation counts, co-authorship adjustments, and authorship positions, emphasizing meaningful research impact rather than mere publication volume.
The 2025 update incorporates data indexed by Scopus as of August 1, 2025, covering citations through the end of 2024. The methodology includes adjustments for self-citations, classification into detailed scientific subfields, and considerations for retracted papers, ensuring transparent and rigorous evaluation across disciplines.
