Frequently asked questions

How many scientists from Greece are in the 2026 Stanford Top 2% list?

1,184 scientists affiliated with Greece are on the 2026 single-year list, and 1,243 are on the career-long list.

Which institute in Greece has the most Top 2% scientists?

On the 2026 career-long list, Aristotle University of Thessaloniki has the most listed scientists from Greece, with 165. It is followed by National Technical University of Athens (NTUA) with 123.

How has the number of Top 2% scientists in Greece changed since 2020?

On the career-long list, Greece went from 648 scientists in 2020 to 1,243 in 2026, a change of +91.8%.

What is the difference between the single-year and career-long lists?

The single-year list ranks scientists on the citations their work received in one year. The career-long list ranks them on citations across their whole career. Both lists are published every year, and a scientist can be on one, both or neither.

What is the official source of this data?

The rankings come from the science-wide author databases of standardized citation indicators published by Ioannidis et al. in the Elsevier Data Repository, updated every year. TOPSCINET, an independent platform, organises that data by country, year, institute and field, so you can compare and explore it.
