Academics at the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, have been recognised in the 2026 AD Scientific Index, with 100 researchers featured among Ghana’s top 1,000 scientists, underscoring the University’s growing contribution to global research and scholarship.
The rankings, based on research productivity, citation impact and international visibility, place several KNUST scholars among the country’s highest-performing researchers across disciplines including medical sciences, engineering, natural sciences, agriculture and social sciences.
Leading the KNUST cohort is Professor Ellis Owusu-Dabo, ranked ninth in Ghana and first within the University, followed by Professor Fred Stephen Sarfo (10th) and Professor Daniel Ansong (18th), reflecting a strong presence in medical and health sciences research.
Other top-ranked academics include Professor Tsiri Agbenyega (23rd), Professor Robert Clement Abaidoo (24th), Professor Richard Odame Phillips (26th), Professor Godfred Darko (34th) and Professor William Otoo Ellis (38th).
The rankings also feature a strong representation from business, engineering and environmental sciences. Scholars such as Professor De-Graft Owusu-Manu (51st), Professor Nathaniel Boso (54th), Professor Osei Akoto (59th) and Professor Tsiri Agbenyega in atmospheric physics (65th).
Further entries include Professor Christian Agyare (78th), Professor Adu-Boahen Raymond (88th), Professor Ibok Oduro (89th), Professor Kofi Agyekum (94th), Professor Eric Woode (103rd) and Professor Dadson Awunyo-Victor (104th), spanning pharmacy, biological sciences, food science, civil engineering and agricultural economics.
Earlier listed scholars such as Professor Philip Antwi-Agyei, Professor Christian Agyare, Professor De-Graft Owusu-Manu and Professor Nathaniel Boso further reinforce KNUST’s footprint in environmental science, pharmacy, engineering and business research.
The list also features senior and emerging researchers across a wide range of fields, including agriculture, architecture, economics, education and public health, demonstrating the depth of expertise within the University’s academic community. From climate change and infectious diseases to construction management and biotechnology, the rankings reflect research aligned with real-world challenges.
The AD Scientific Index evaluates scientists using indicators such as total citations, H-index and i10-index, drawing from global academic databases to measure both productivity and impact. The inclusion of 100 KNUST academics highlights sustained research output and increasing international recognition.
The rankings also point to a strong pipeline of researchers contributing to knowledge generation and policy-relevant work, particularly in areas critical to national and regional development, including health systems, food security, environmental sustainability and technological innovation.
University officials say the recognition affirms KNUST’s position as a leading research institution in Ghana and beyond, while reinforcing ongoing efforts to support high-impact research, interdisciplinary collaboration and global academic visibility.
