Best Business and Management Scientists 2026 in Nigeria

A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a specialized variant of the traditional H-index. The D-index exclusively considers papers and citation metrics relevant to the specific discipline under examination—in this case, Business and Management—thus ensuring that the ranking accurately reflects impact within the relevant field rather than a researcher’s general scholarly output.

Scope and Criteria for Inclusion

The ranking draws on an extensive analysis of 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources spanning all scientific disciplines. Within this pool, 1,xxx scientists specializing in Business and Management were identified and thoroughly evaluated for inclusion.

To qualify for the ranking, candidates needed to meet multiple rigorous criteria:

• A minimum D-index of 30 in Business and Management, reflecting a threshold of significant scholarly contribution within the discipline.
• The majority of their top-tier publications had to be dedicated to research in Business and Management.
• Recognition of measurable awards and achievements explicitly related to Business and Management further factored into qualification.

The D-index threshold is dynamically set as increments of 10 relative to the estimated total number of scholars in each discipline. This method guarantees that the top 1% of leading researchers are systematically incorporated while maintaining disciplinary relevance. Additionally, to ensure consistency, a maximum proximity of 30% difference between a scientist’s general H-index and their D-index is maintained, verifying that their overall scientific influence closely aligns with their discipline-specific contributions.

Verification and Methodological Rigor

At Research.com, we acknowledge that raw bibliometric data alone can never fully capture the quality or nuance of a scientist’s scholarly output. Therefore, all scientist profiles included in the ranking underwent a careful manual verification process. This involved cross-correlating publication records against a wide range of trustworthy sources to validate authorship, affiliation, and relevance to Business and Management research.

While the ranking position is driven by the D-index sourced from OpenAlex and CrossRef — the most prominent and well-established databases available to the research community — the number of publications in prominent journals and major conference proceedings is considered a valuable secondary signal of a scientist’s contribution to their specific field. Though not directly factored into ranking calculations, this dimension adds an additional layer of context for understanding scholarly impact.
