Which keywords describe research in Iran?

By fractional works in 2022–2025, weighted toward what it does more of than the world: Epidemiology, Biomedical Applications, Inflammation, Nanoparticles, Depression, Nanomaterials, Oxidative Stress and Quality of Life.

How many world-class institutions does Iran hold?

Average quality and elite capacity disagree by construction, and both are worth knowing: the first is decided by a country’s whole institution population, the second counts the institutions it holds at the top. One square per institution.

101st to 500th1501st to 1,000th9

Bands are exclusive, so the squares add up to 10 — the institutions it holds in the world top 1,000 — and not to four times it.

Which universities in Iran lead research?

University of Tehran, Tehran University of Medical Sciences and Iran University of Science and Technology rank highest in Iran on research quality in 2022–2025.
