A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined metric that isolates a researcher's scholarly output and citation impact within a specific discipline—in this case, Physics. This approach ensures that the assessment reflects the individual’s contributions solely relevant to the examined area of research.
Scope of Research and Eligibility Criteria
This edition evaluated a total of 188,172 scientist profiles compiled from a variety of bibliometric data sources across all academic disciplines. Among these, 71 scientists specializing in Physics were specifically identified and analyzed.
To qualify for inclusion in the ranking, a researcher’s D-index had to be at least 70, with a majority of their Tier 1 publications situated within the area of Physics. Additionally, consideration was given to each scientist’s awards and notable achievements within the field.
The threshold for the D-index required to consider top researchers is set as an increment of 10 based on the estimated total number of scholars within each discipline. This scalable approach guarantees the inclusion of the top 1% of leading scholars in the respective research areas. Furthermore, to maintain coherence between general and discipline-specific performance, the proximity between a scientist’s overall H-index and their D-index was set to be within 30% or less.
Verification and Validation Procedures
The Research.com team recognizes that raw bibliometric data alone can never serve as an absolute tool to evaluate the full scholarly output of researchers. To ensure accuracy and fairness, all scientist profiles included in the ranking were manually verified and cross-correlated against publications across a wide range of trusted academic sources.
While the number of papers published in prominent journals and conference proceedings is not a direct factor influencing a researcher’s position in the ranking, it is nonetheless regarded as a valuable secondary signal reflecting their contribution to specific scientific domains.
The final position in the ranking is established exclusively based on each researcher’s verified D-index derived from consistently curated data from OpenAlex and CrossRef.
