Institutional ranking positions are determined by calculating the sum of D-indexes (Discipline H-index) for all affiliated scholars whose principal publication area is Chemistry. The D-index exclusively aggregates publications and citation data specific to Chemistry, offering an accurately focused reflection of research impact in the discipline.
Scope of Research and Inclusion Criteria
The ranking has a wide-reaching scope, building upon an initial evaluation of 279,971 scientist profiles, collected from diverse bibliometric data repositories. Of these, 279,971 scientists with a primary focus on Chemistry were shortlisted and rigorously analysed.
To ensure only highly impactful researchers are included, the qualifying D-index threshold for each scientist was set at 40, with the stipulation that the majority of their distinguished publications reside within Chemistry. Notably, researchers’ awards and achievements in Chemistry were considered as part of the assessment process. Additionally, the threshold for top researchers is adjusted in increments of 10, reflecting the total number of scholars in each discipline, and upholding the inclusion of the top 1% of global scholars.
Scholars included must maintain a 30% or less proximity between their general H-index and their D-index, further ensuring the discipline-specific relevance of their research output. Scientists’ accolades and recognition in Chemistry served as additional qualitative metrics in the evaluation process.
Verification Practices and Data Reliability
Research.com recognizes that, while quantitative analysis provides a critical foundation, raw data alone cannot comprehensively evaluate scholarly impact. Consequently, every scientist profile featured in the ranking has been manually verified and cross-validated with publications from a diverse array of reputable sources. While the number of publications in major journals and conference proceedings does not directly affect ranking position, it is considered a valuable secondary indicator of a researcher’s disciplinary contribution.
A scholar’s positioning within the ranking relies on the H-index as reported by OpenAlex and CrossRef, currently the most authoritative and widely recognized bibliometric databases available to the scientific community. The rigorous methodology and verification steps underscore Research.com’s commitment to accuracy and transparency. To explore the methodology in greater detail, please visit our methodology page.
