A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a tailored metric that accounts exclusively for papers and citation statistics relevant to the examined discipline—in this case, Chemistry. This discipline-specific filter ensures that the ranking accurately reflects productivity and impact within the field rather than general scholarly activity.
Scope of Research and Qualification Criteria
The scope of this ranking encompasses 279,971 scientist profiles identified across all disciplines from a diverse array of bibliometric data sources. For Chemistry specifically, a refined cohort of 18 scientists was analyzed.
To qualify for inclusion in the ranking, a scientist's D-index must be at least 40, with the majority of their tier publications clearly situated within the Chemistry discipline. Additionally, a scientist’s awards and distinguished achievements in the field were also taken into consideration.
The D-index threshold for each discipline is calibrated in increments of 10 based on the estimated total number of scholars and is set to ensure that the top 1% of leading scholars are represented in the list. Furthermore, to maintain discipline-focus credibility, a proximity criterion is applied whereby the difference between a scientist’s general H-index and their D-index should not exceed 30%.
Verification Practices
Understanding that raw bibliometric data alone cannot serve as an absolute measure of academic contribution, the Research.com team implemented thorough manual verification processes. All profiles included in the ranking were cross-checked against publications indexed in a broad spectrum of trustworthy sources. This rigorous verification safeguards against data inaccuracies and ensures the ranking’s integrity.
While not directly influencing the ranking position, the volume of papers published in prominent journals and conference proceedings is recognized as a valuable secondary signal of a scientist’s research contribution within Chemistry.
The primary criterion for ranking remains the D-index derived from OpenAlex and CrossRef datasets. To learn more about the detailed methodologies and data processing protocols employed, readers are encouraged to visit our methodology page.
