Frequently asked questions

How many scientists from Thailand are in the 2020 Stanford Top 2% list?

187 scientists affiliated with Thailand are on the 2020 single-year list, and 136 are on the career-long list.

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

On the 2020 career-long list, Mahidol University has the most listed scientists from Thailand, with 22. It is followed by Chulalongkorn University with 15.

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.
