A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric measure that includes only the publications and citation metrics relevant to the examined discipline—in this case, Physics. This approach ensures that the ranking reflects a researcher’s true impact and productivity within their specific field of expertise.
Scope of Research and Inclusion Criteria
The ranking was compiled through an examination of 279,971 scientist profiles identified from a diverse array of bibliometric data sources spanning all academic disciplines. Specifically for the field of Physics in the Philippines, 1,XXX scientist profiles were carefully evaluated.
To qualify for inclusion in the ranking, a scientist had to meet a minimum D-index threshold of 70, with the majority of their tier publications focused explicitly on Physics. Additionally, awards and notable achievements within the discipline were considered as supplementary factors reinforcing their standing.
The D-index threshold for top researchers is established as increments of 10, calibrated according to the estimated total number of scholars within each discipline. This methodology is designed to guarantee that the top 1% of leading scholars are consistently incorporated into the list. Furthermore, to ensure disciplinary relevance, only researchers displaying a proximity of 30% or less between their general H-index and their D-index are considered, thereby filtering for depth of expertise.
Verification Practices and Methodological Rigor
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. Consequently, all scientist profiles underwent rigorous manual verification and were cross-checked against publications indexed in a wide range of trustworthy sources, ensuring accuracy and validity.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s rank, it remains an invaluable secondary indicator of a scientist’s contribution to their discipline, providing additional context beyond citation metrics.
The D-index remains the primary metric for ranking scientists, generated exclusively from meticulously curated data derived from OpenAlex and CrossRef. These databases represent the foremost and most widely recognized bibliometric resources accessible to the research community worldwide.
