Prof. Anna Visvizi has been included in the prestigious Stanford–Elsevier Top 2% Scientists list, which recognizes researchers with the greatest impact on global science. This distinction confirms the international reach and significance of her research.
Among global indicators of research influence, two rankings occupy a particularly prominent place: the Stanford–Elsevier Top 2% Scientists list and the Clarivate Highly Cited Researchers (HCR) program. Although based on different methodologies, both aim to identify scholars whose work significantly shapes science at the global level.
Stanford–Elsevier Top 2% Scientists: What Is It and What Does It Measure?
The Stanford–Elsevier list, developed by the team of Prof. John Ioannidis (Stanford University), draws on data from Elsevier’s Scopus database. It uses a composite bibliometric indicator, the so-called c-score, which combines total citations, the h-index, co-authorship adjusted through the hm-index, and field-normalized weights for publications where the researcher is the first, last, or sole author. By comparing results across 174 scientific subfields, the list highlights those scientists who belong to the top 2% worldwide. It includes two dimensions of impact: career-long and single-year, thus capturing both the durability and the current relevance of a researcher’s scholarly influence.
The Clarivate Highly Cited Researchers list, based on the Web of Science (WoS) database, identifies researchers whose publications rank among the top 1% most cited globally within an eleven-year period.
Both rankings provide valuable insight into a researcher’s standing in the international academic community. The Stanford–Elsevier list offers a broad perspective, spanning an entire career as well as annual performance snapshots, while Clarivate presents a more selective view of exceptional, recent impact.
Being featured on either list indicates that a researcher’s body of work is not only widely recognized but also substantively influential, i.e. it shapes international academic debate, inspires peers, and drives the development of science globally.
Anna Visvizi, Ph.D. (dr hab.), Professor SGH, Vice-Dean of the SGH Doctoral School, Head of the International Economic Policy Department (ZMPE). Editor-in-Chief of Transforming Government: People, Process and Policy (TGPPP) & Digital Policy, Regulation and Governance (DPRG). Economist and political scientist, editor, researcher and political consultant with extensive experience in academia, think-tank and government sectors in Europe, including the OECD. The author of several published works (Elsevier, Routledge, Elgar Publishing, Springer, Emerald Publishing). Her expertise covers issues pertinent to the intersection of politics, economics and ICT. This translates in her research on applied aspects of ICT, including AI, in such domains as smart cities/smart villages, geopolitics, and innovation management.
