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

On the 2025 career-long list, University Politehnica of Bucharest has the most listed scientists from Romania, with 22. It is followed by Universitatea Babeș-Bolyai with 15.

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

On the career-long list, Romania went from 100 scientists in 2020 to 220 in 2025, a change of +120.0%.

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.
