The annual ranking highlights researchers whose work has had significant global influence, measured through widely accepted metrics such as citation counts, publication quality, h-index, and overall contribution to knowledge. It is regarded as one of the most reliable ways of tracking the research impact scientists are making across the globe.  

• Professor Obiageli Eunice Nnodu – Rank 771,295

• Dr. Oludare Isaac Abiodun – Rank 87,938

The TopSciNet list is updated annually and evaluates millions of researchers across various disciplines worldwide, applying recognised measures such as citation counts, h-index, and other standardised indicators to rank scientists.
