Data Sources and Citation Metrics
The 5th edition of the Research.com Best Microbiology Scientists in Madagascar Ranking is founded on extensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple additional reputable data sources. The bibliometric data used to derive citation-based metrics for this ranking were collected on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric measure that considers only papers and citation metrics directly relevant to the examined discipline of Microbiology. This ensures that the ranking reflects scholarly impact and productivity within a specific field rather than general academic output.
Scope and Criteria of the Ranking
The ranking was compiled following a comprehensive examination of 187,659 scientist profiles aggregated from diverse bibliometric data sources across all scientific disciplines. From this extensive dataset, 1 scientist specializing in Microbiology in Madagascar qualified for inclusion. To be considered for the ranking, a researcher’s D-index had to meet or exceed a threshold of 40, with the majority of their tiered publications predominantly in Microbiology. In addition to bibliometric thresholds, notable awards and achievements in the field of Microbiology were also factored into the evaluation process.
The D-index threshold is dynamically set as increments of 10 relative to the estimated total number of scholars in each discipline, thereby ensuring that approximately the top 1% of leading scholars worldwide are included in the ranking. Additionally, to maintain disciplinary relevance, a scientist’s general H-index and D-index must not differ by more than 30%, preserving a strong correlation between overall impact and domain-specific influence.
Verification and Validation Practices
Understanding the limitations of raw bibliometric data, the researchers behind this ranking implemented a rigorous verification process. All scientist profiles were manually reviewed and cross-validated against publications in a broad array of trustworthy sources and databases to confirm authorship, subject relevance, and citation accuracy. While the number of papers published in prominent journals and conference proceedings does not directly influence ranking placement, it serves as a valuable secondary indicator of a scientist’s contribution to the Microbiology research community.
The final ranking position is firmly based on the D-index calculated from data obtained through OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric repositories accessible to the global research community.
