OpenAlex returns no single authoritative profile for "Yinyin Yan." The strongest true name match is a profile with only 7 works, 69 total citations, and h-index 5, lacking an ORCID and institutional affiliation . A second profile with the same name (ORCID 0009-0009-6094-3215) holds just 1 work and 0 citations, suggesting the publication record is split across unmerged identities .
Critically, the top-ranked search result is Yinyin Wu (263 works, h-index 26), whose record spans titanium-oxo cluster chemistry, carbon-economics, and nutrition meta-analyses β an incoherent topical spread that strongly indicates OpenAlex conflation of multiple distinct people under one entity . Attributing this record to Yinyin Yan would be a confabulation.
Bottom line: the available, defensible evidence supports only a small early-career or peripherally-indexed researcher (h-index β€5 across the merged fragments). No work titles, venues, or topics are supplied for the genuine Yan profiles, so research rigor, novelty, and communication quality cannot be honestly assessed. What would change this conclusion: an ORCID-linked master profile with the actual publication list, which would allow re-scoring on primary evidence rather than fragmented metadata.
