Data Sources and Ranking Methodology
The 5th edition of the Research.com Best Microbiology Scientists in Malaysia Ranking is primarily derived from comprehensive bibliometric data sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. The citation-based metrics used to devise this ranking were collected on January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively considers publications and citation counts relevant to the examined discipline, in this case, Microbiology, ensuring a focused and accurate reflection of discipline-specific research impact.
Scope of Research and Qualification Criteria
This ranking was compiled following an extensive examination of 187,659 scientist profiles aggregated from diverse bibliometric sources across all scientific disciplines. Within this dataset, specifically 5 scientists were identified and evaluated for their contributions to Microbiology. To qualify for inclusion in the ranking, candidates were required to have a minimum D-index threshold of 40. Additionally, a majority of their tier publications needed to be explicitly within the field of Microbiology, and their notable awards and achievements in this discipline were also taken into account.
The D-index threshold for identifying top researchers is calibrated as increments of 10, contingent on the estimated total population of scholars within each discipline. This dynamic threshold setting guarantees inclusion of approximately the top 1% of leading scholars in the ranking. Furthermore, a proximity criterion ensures that the difference between a scientist’s overall H-index and their D-index does not exceed 30%, reinforcing the focus on disciplinary relevance while accounting for overall scholarly impact.
Additional Verification and Validation Practices
Understanding the limitations of raw bibliometric data, the Research.com team has incorporated rigorous manual verification procedures in the compilation of this ranking. Each scientist profile was meticulously cross-verified against an array of trustworthy publication sources to authenticate the accuracy and relevance of the scholarly output attributed to them.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it serves as an important secondary indicator of their contribution to advancing Microbiology research.
The final rank order is established solely based on each researcher’s D-index, calculated through data aggregated from OpenAlex and CrossRef—the two most prominent, widely recognized, and accessible bibliometric databases used by the global research community.
