Not ranked in the World University Rankings

We couldn’t find an official student count for this university, so its alumni outcomes can’t be measured per student. It is listed in the Research Index but not ranked overall.

Research Index

The Research Index ranks a university only when it has at least 1,500 fractionally counted core publications over four years, so that a handful of highly cited papers can’t produce an extreme score. Its field ranks (where it has 200 or more papers in a field) and all of its data are shown here.

Core publications, fractional counting, field-normalised citation shares. Brackets show Leiden’s stability interval. Collaboration and open-access shares use full counting and aren’t field-normalised. Retraction counts come from the Retraction Watch database and include publishers’ mass retractions as well as honest-error retractions; a retraction is not by itself evidence of misconduct, and the count is never scored.

Position over time

Not enough periods to show a trend.

The same method applied to each 4-year publication window. The number of ranked universities grows from period to period, so position is shown as a share of the field.

How other rankings place it

–Research Index 2026 (not ranked)
–QS 2027 (not in top 100)
–THE 2027 (not in top 100)
–ARWU 2026 (not in top 100)

Other rankings are cited for comparison. The Research Index measures research only; QS and THE also use reputation surveys and figures universities submit, and ARWU counts prize winners and total output.
