We are delighted to announce that some of our outstanding lecturers have been recognised among the Top Scientists in the world by the AD Scientific Index 2025–2026 Rankings.
The AD Scientific Index is a respected global platform that ranks scientists and institutions using reliable data on research output, citations, and academic impact. It goes beyond numbers to provide visibility, recognition, and valuable support for researchers and institutions worldwide.
This recognition is not only a personal achievement for our celebrated academics but also a clear confirmation of the progress we are making as a university under the leadership of our Vice-Chancellor, Professor Prof. Kate Azuka Omenugha, fnipr.
Her administration’s 3V Agenda of Values, Viability, and Visibility has placed research excellence at the heart of COOU’s growth. Visibility is a key pillar of this agenda, and these rankings show that COOU is fast becoming an emerging leader in research, teaching, and innovation in Nigeria and beyond.
