Bibliometric data used to devise the citation-based metrics were collected on January 12, 2026. The ranking positions are determined by a researcher’s D-index (Discipline H-index), which specifically focuses on papers and citations within the examined discipline of Earth Science. This allows for a targeted and discipline-relevant evaluation of research impact.
Scope of Research and Inclusion Criteria
The ranking was developed following a rigorous examination of 279,971 scientist profiles identified across a variety of bibliometric data sources covering all disciplines. Within this extensive dataset, only 2 scientists specializing in Earth Science in Serbia met the criteria for inclusion.
To qualify for this ranking, a scientist’s D-index had to be at least 30. Additionally, the majority of their tier publications were required to be firmly rooted in the Earth Science domain. Consideration was also given to notable awards and achievements specifically related to Earth Science, acknowledging recognized expertise and excellence beyond citation metrics alone.
The D-index threshold is carefully calibrated, increasing in increments of 10 based on the estimated total number of scholars per discipline. This ensures that the ranking reliably includes the top 1% of leading scholars within Earth Science. Furthermore, to confirm the disciplinary focus of candidates, the proximity between their overall H-index and D-index was maintained at 30% or less, reinforcing that their research impact is concentrated within the evaluated field.
Additional Verification Practices
Recognizing that raw bibliometric data cannot serve as an absolute measure of a scholar’s output, the Research.com team conducted extensive manual verifications of all scientist profiles. Researchers’ publication records were cross-correlated with a broad range of trustworthy sources to ensure accuracy and validity.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, this metric is acknowledged as an important secondary indicator of scientific contribution within Earth Science.
The official position in the ranking is established solely based on each researcher’s D-index, calculated from data aggregated by OpenAlex and CrossRef. These sources represent the most recognized and comprehensive bibliometric datasets currently accessible, reinforcing the reliability of the ranking outcomes.
