A university's position in the ranking is determined by the aggregate D-index (Discipline H-index) of all ranked scholars affiliated with that institution, provided their principal publication area is Chemistry. The D-index measures only publications and citation metrics relevant to each examined discipline, guaranteeing specificity and precision in assessing research impact within Chemistry.
Scope of the Analysis
The ranking draws on a vast and representative sample of the global scientific community. A total of 279,971 scientist profiles—identified from various bibliometric databases—were initially examined, with 279,971 profiles specifically from Chemistry undergoing detailed analysis.
Eligibility required scholars to have a minimum D-index threshold of 40, with the majority of their significant publications concentrated in Chemistry. Scientists' awards and achievements within the field also contributed to their assessment. Notably, the D-index threshold for inclusion of top researchers is set dynamically in increments of 10, depending on both the number of scholars in each discipline and the overarching goal of incorporating the top 1% of leading experts per field. Furthermore, there must be a proximity of 30% or less between a scholar’s overall H-index and their D-index, to ensure the profile is genuinely representative of Chemistry scholarship. Once again, notable achievements and recognition in Chemistry play an important role in the review process.
Verification and Quality Assurance
The Research.com team understands that bibliometric data alone cannot provide a full or entirely accurate evaluation of scientific contributions. Therefore, every scientist profile was subject to manual verification and cross-checked with an array of authoritative publications and sources.
While the number of papers in prominent journals and conference proceedings is not a formal ranking criterion, it is acknowledged as a valuable supplementary indicator of a scientist’s impact in their field.
The final positions in the ranking are determined using each researcher's H-index, as established by data from OpenAlex and CrossRef—both regarded as premier bibliometric databases within the research community.
