Frequently asked questions

How many scientists from Romania are in the 2021 Stanford Top 2% list?

190 scientists affiliated with Romania are on the 2021 single-year list, and 133 are on the career-long list.

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

On the 2021 career-long list, Universitatea Babeș-Bolyai has the most listed scientists from Romania, with 11. It is followed by Universitatea din Bucuresti with 10.

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 133 in 2021, a change of +33.0%.

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.
