This year, 25 SSPC researchers are recognised as leading experts in their fields in the rankings produced by Stanford University scientists in cooperation with publisher Elsevier and SciTech Strategies, based on Scopus data.

Elsevier/Stanford University have created a publicly available database of top-cited scientists that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator (c-score).

Separate data are shown for career-long and, separately, for single recent year impact. Scientists are classified into 22 scientific fields and 174 sub-fields to ensure fair and comprehensive representation.

Researchers are across 8 of our institutional partners:

• University of Limerick (UL)
• Trinity College Dublin (TCD)
• Royal College of Surgeons in Ireland (RCSI)
• Dublin City University (DCU)
• University College Dublin (UCD)
• Maynooth University (MU)
• University of Galway
• University College Cork (UCC)

The Stanford/Elsevier list of top scientists for 2025 is based on citations from 2024, and uses metrics like h-index, co-authorship adjustments, and a composite citation score (c-score), which reflects a scientist’s influence rather than just their publication count

The full list of the most-cited scientists in the world can be accessed from the Elsevier Data Repository.
