The bibliometric data used to derive the citation-based metrics were collected on January 12, 2026. The position of each scientist within the ranking is determined by their Discipline H-index (D-index), a refined metric that evaluates scholarly impact exclusively within the examined discipline—in this case, Chemistry. The D-index considers only publications and citations relevant to the field, providing a more focused and discipline-specific assessment of research influence.
Scope of Research and Inclusion Criteria
The ranking was developed by analyzing a total of 279,971 scientist profiles, identified from a broad spectrum of bibliometric sources spanning all research disciplines. Within this comprehensive data set, 402 scientists specializing in Chemistry were specifically examined.
To qualify for inclusion in this Chemistry-focused ranking, a scientist’s D-index had to be at least 40. Additionally, a majority of their tier publications needed to be demonstrably within the field of Chemistry. Beyond bibliometrics, scientists’ awards and notable achievements in Chemistry were also factored into the evaluation to ensure recognition of distinguished contributions.
The threshold for the D-index is set in increments of 10 that reflect the total number of scholars estimated in each discipline. This approach ensures inclusion of the top 1% of leading scholars, maintaining a consistently high standard for the ranking.
Furthermore, eligibility requires that the difference between a scientist’s general H-index and their D-index remains within 30%, thereby confirming a close alignment between overall scholarly impact and discipline-specific research excellence.
Verification Practices
Recognizing that raw bibliometric data alone cannot fully encapsulate a scholar’s output and impact, our research team undertook meticulous manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a diverse range of trustworthy and authoritative sources to confirm accuracy and relevance.
While the number of papers published in prominent journals and recognized conference proceedings does not directly influence a researcher’s position in the ranking, it is treated as a valuable secondary indicator of scholarly contribution within the field.
The final ranking positions are established exclusively using each researcher’s D-index as calculated from OpenAlex and CrossRef data, ensuring consistency and reliability through the use of well-vetted bibliometric resources.
