About the Stanford–Elsevier Ranking
The Stanford–Elsevier database, updated annually, identifies the world's most-cited researchers. One of its contributors is John P. A. Ioannidis, Professor of Medicine at Stanford University and a researcher specialising in meta-research. The results are published in the Elsevier Data Repository and are based on standardised citation indicators derived from Scopus data.
The assessment takes into account several indicators, including citation counts, the h-index, metrics that account for co-authorship, and researchers' positions in publication author lists. These indicators are combined into a composite citation score (c-score), which measures the citation impact of scientific work rather than simply the number of publications.
The inclusion of Tallinn University researchers in the ranking highlights the international visibility of research conducted at the university and its contributions across different scientific disciplines.
More information about other Tallinn University researchers included among the world's top 2% most-cited scientists, based on both single-year and career-long citation impact, is available in the Stanford–Elsevier report.
