Sankore

Named after the University of Sankore in Timbuktu — one of the world’s oldest centres of learning. Every figure here is computed from work-level records in our own graph, never copied from a source’s summary count.

Built from

OpenAlex — works, authorships, subject classification
ROR — institutional identity
ORCID — researcher identity
Crossref — publisher confirmation

What we cover

Coverage is partial and says so. A country appears with its research output only once its works have been swept; until then the portal shows whatever the graph happens to hold for it and labels it as exactly that.

ORCID, self-asserted

ORCID 0000-0002-7262-7908

This profile carries an ORCID the researcher published on their own record — the strongest evidence available short of a human confirming it.

Computed over the works the graph holds, so it is a floor rather than a career figure.
