Scope of Research and Qualification Criteria
The comprehensive scope of this ranking involved the examination of 279,971 scientist profiles collated from a diverse array of bibliometric sources, encompassing all scientific disciplines. From this dataset, a cohort of 800 scientists specializing in Chemistry was identified and analyzed in detail.
To qualify for inclusion in the ranking, a researcher was required to have a D-index of at least 40, ensuring a baseline of significant scholarly influence within Chemistry. Furthermore, a majority of a qualifying scientist’s tier publications had to pertain specifically to Chemistry, assuring disciplinary relevance. Recognition of awards and achievements in Chemistry served as an important supplementary factor in the evaluation process.
The D-index threshold for delineating top researchers is calibrated in increments of 10 based on the estimated total number of scholars in each discipline, ensuring that the top 1% of leading experts are represented across varied fields. Additionally, to verify the discipline-specific nature of their impact, the difference between a scientist’s general H-index and their D-index was required to be no greater than 30%.
Additional Verification Practices
Recognizing the limitations inherent in raw bibliometric data as a standalone evaluative tool, the ranking process incorporated extensive manual verification procedures. Each scientist profile was meticulously reviewed and cross-checked against publications indexed in a broad spectrum of reputable sources. This rigorous validation helps safeguard the integrity and accuracy of the ranking.
While the number of papers published in high-impact journals and prominent conference proceedings does not directly influence the position within Research.com’s ranking, it remains a valuable secondary indicator of a scientist’s contribution and stature within their field.
The final positions in the ranking are established based on the D-index values derived from OpenAlex and CrossRef—two of the most prominent and respected bibliometric databases accessible to the international research community.
