Outstanding research performance in academia is often measured by how frequently a scholar’s work is cited by others. Each year, the ‘Highly Cited Researchers’ list recognizes leading experts in specific fields whose publications are among the most frequently cited worldwide. This year, three researchers from Saarland University have once again earned a place on the prestigious list, reflecting their exceptional academic reputation.

The following text has been machine translated from the German with no human editing.

These three researchers from Saarland University are “Highly Cited Researchers”:

Andreas Keller, Professor of Clinical Bioinformatics at Saarland University (listed in the ‘interdisciplinary’ category).
He also received this award in 2024 and 2023.

Volker Presser, Professor of Energy Materials at Saarland University (listed in the ‘interdisciplinary’ category).
He also received this award in 2023, 2022, 2021 and 2018.

Ori Staszewski, senior physician at the Institute of Neuropathology at Saarland University (listed in the ‘interdisciplinary’ category).
He also received this award in 2024, 2023 and 2021.

To determine the “Highly Cited Researchers”, the US company Clarivate evaluates its “Web of Science” database every year, which covers scientific publications from a wide range of subjects. The compilation lists 21 subject areas in the natural sciences, life sciences and social sciences, as well as the “Cross-Field” category, which covers interdisciplinary publications.

The ranking lists all researchers who have had a significant impact on their field by publishing several frequently cited works over the last decade and who are thus among the top one per cent of the most cited publications in their academic field. In addition to the pure number of citations, a qualitative analysis and expert opinion are also taken into account, so that the “Highly Cited Researchers” award is not only a summary award but also a scientifically evaluated one.

This year, 6,868 scientists from 60 countries and regions were selected for the list of Highly Cited Researchers, with a total of 7,131 Highly Cited Researcher Awards being presented (some researchers were recognised in more than one field). 86.1 per cent of the awards are concentrated in just ten countries and regions, and 74.6 per cent in the top five alone, illustrating a remarkable concentration of the world’s best research talent. With 363 award-winning researchers, Germany ranks fourth among scientific locations. The United States has the highest concentration of awards worldwide with 2,670 in 2025, followed by China (1,406) and the United Kingdom (570). Australia ranks fifth with 312 awards.
