Best Business and Management Scientists 2026 in Tunisia

A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that measures impact specifically within the examined discipline. The D-index considers only papers and citation metrics directly relevant to Business and Management, thereby providing a focused and discipline-specific evaluation of research performance.

Scope of Research and Inclusion Criteria

This edition reviewed an extensive pool of 279,971 scientist profiles identified across a wide array of bibliometric data sources encompassing all scientific disciplines. From this broad spectrum, the ranking specifically examined 1,138 scientists active in the field of Business and Management.

To qualify for inclusion in the ranking, researchers had to meet a minimum D-index threshold of 30, ensuring a high standard of scholarly impact and productivity. Additionally, a majority of their tier publications needed to be concentrated within Business and Management, affirming their core expertise in the discipline. Awards and notable achievements in the field were also taken into account as supplementary factors.

The D-index threshold is calibrated dynamically in increments of 10, corresponding with the estimated size of the discipline’s scholarly community. This approach guarantees the inclusion of the top 1% of leading researchers in Business and Management, striking a balance between exclusivity and comprehensive coverage. Furthermore, the methodology mandates a proximity of 30% or less between a scientist’s overall H-index and their discipline-specific D-index, thus maintaining coherence between their general academic impact and specialized influence.

Verification and Validation Procedures

The team behind this ranking recognizes that raw bibliometric data alone cannot be an absolute measure of a scholar’s contributions. Consequently, every scientist profile included in the ranking underwent manual verification and was cross-correlated against publications indexed in a wide range of reputable and trustworthy sources. This meticulous process strengthens the credibility and accuracy of the ranking results.

While not directly factored into the positioning within the Research.com rankings, the volume of publications in renowned journals and conference proceedings is respected as an important secondary indicator of a researcher’s influence and contribution to their field.

Ultimately, the ranking is established based on each researcher’s D-index as determined from data gathered from OpenAlex and CrossRef, which remain the most prominent and reliable bibliometric databases accessible to the scientific community today.
