A university’s position in the ranking is determined by the sum of the D-indexes (Discipline H-index) of all scholars primarily affiliated with the institution and whose main research area is Chemistry. The D-index is a discipline-specific variant of the H-index, taking into account only those publications and citation data relevant to Chemistry. This methodology ensures that an institution's standing reflects the impact and productivity of its scholars within the field of Chemistry.
Scope of Research
The current edition scrutinized 279,971 scientist profiles identified from a variety of bibliometric data sources. Of these, 279,971 scientists specializing in Chemistry were selected for focused analysis. To be included in the ranking, a scientist needed to meet a minimum D-index threshold of 40 and demonstrate that the majority of their leading publications were in the field of Chemistry. Moreover, scientists’ professional awards and achievements in Chemistry were factored into the assessment to ensure recognition of scholarly distinction.
The D-index threshold for the recognition of top researchers is dynamically adjusted by increments of 10, in accordance with the overall population of qualifying scholars within each discipline, and calibrated to ensure the top 1% of leading scientists are represented. To maintain discipline specificity, only those scientists with a difference of 30% or less between their H-index and D-index were considered. Further, awards and recognitions in the scientist's field of study served as an additional evaluative metric.
Additional Verification Practices
The team behind Research.com acknowledges that raw bibliometric data alone cannot fully capture the qualitative dimension of scholarly contributions. Therefore, every scientist profile included in the ranking underwent manual verification, along with cross-correlation against publications catalogued in a wide selection of respected, trustworthy sources.
While the number of papers published in prominent journals and conference proceedings is not a direct ranking factor, it remains a valuable secondary indicator of a scientist's influence and contribution to advancing Chemistry. Each researcher's H-index, utilized in the ranking, was calculated using information from OpenAlex and CrossRef, ensuring that the evaluation leveraged the most comprehensive and up-to-date citation datasets available.
