Institutions are evaluated based on the collective scientific impact of their affiliates, measured as the sum of the D-indexes (Discipline H-index) of all ranked scholars whose primary research focus lies in Chemistry. The D-index is a rigorous metric that includes exclusively publications and citation data relevant to Chemistry for the scholar under consideration.
Scope of Research and Inclusion Criteria
The scope of the ranking is underpinned by the examination of 279,971 scientist profiles identified from a diverse set of bibliometric data repositories. Among these, 279,971 scientists specializing in Chemistry were analyzed in depth. To ensure the highest standards of inclusion and to feature only impactful contributors, the qualifying threshold for the D-index for each scientist was set at 40, with the stipulation that the majority of their key publications pertain directly to Chemistry.
Additionally, recognized achievements and awards in Chemistry were incorporated as considerations in the evaluation process. The D-index threshold is dynamically calibrated—in increments of 10—to reflect the total number of scholars active in each scientific discipline, while guaranteeing that the top 1% of leading scholars are represented. Furthermore, to bolster disciplinary relevance, a proximity criterion was enforced: the difference between a scientist’s general H-index and their D-index must not exceed 30%. This ensures each scholar's primary impact is within Chemistry.
Additional Verification and Quality Assurance Practices
Recognizing the nuances of bibliometric data, Research.com has implemented comprehensive verification processes to ensure the reliability and fairness of the ranking. While citation metrics are a central pillar, they are not deemed absolute measures of scholarly contribution. Every scientist profile included in the ranking underwent meticulous manual verification; profiles were cross-checked against authoritative publication sources to validate disciplinary alignment and research quality.
Though not a direct metric influencing rank, the number of articles published in prominent journals and conference proceedings is considered a valuable secondary indicator of a researcher’s contribution to their field. The principal H-index data that inform each researcher’s position are sourced from OpenAlex and CrossRef, esteemed for their prominence and reliability within the global research community.
