Top 5 West African scientists in the diaspora driving critical research

Across laboratories in Boston, London, Toronto and Accra, a generation of West African scientists is shaping some of the most consequential research of our time. From artificial intelligence and climate policy to genomics and endocrine biology, these researchers are influencing industries, informing global policy, and redefining Africa’s role in the knowledge economy.For Nigeria and the wider sub-region, their work carries strategic implications. In a world where innovation drives competitiveness, intellectual capital is fast becoming as valuable as natural resources. These five scientists exemplify how West African expertise is contributing to global breakthroughs, and why diaspora engagement should be central to economic policy.

1. Dr. Moustapha Cissé (Senegal) — Advancing Artificial Intelligence for Public Good

Dr. Moustapha Cissé was the former Head of the Google AI Centre in Accra, Ghana, the first Google AI research centre on the African continent. A Senegalese computer scientist, he earned his PhD in Machine Learning from Pierre and Marie Curie University (Sorbonne University) in France and has held research positions at Facebook AI Research (FAIR) and Google.At Google, Cissé led foundational research in machine learning with applications in healthcare diagnostics, agriculture optimisation, language modelling, and climate analytics. His work on algorithmic fairness and bias mitigation addresses one of the most pressing issues in AI governance: ensuring that automated systems do not replicate social inequalities.Artificial intelligence is projected to contribute trillions of dollars to global GDP over the next decade. By building AI capacity in Africa and expanding research into underrepresented languages and datasets, Cissé is positioning the continent not merely as a consumer of digital tools but as a producer of foundational technologies, a shift with significant long-term economic implications.

2. Dr. Fatima Denton (The Gambia) — Climate Science and Sustainable Development

Dr. Fatima Denton is Director of the United Nations University Institute for Natural Resources in Africa (UNU-INRA), based in Accra. She has contributed to the Intergovernmental Panel on Climate Change (IPCC) and held senior advisory roles within multilateral institutions.Her research focuses on climate adaptation, resilience financing, and the economic consequences of environmental degradation in vulnerable economies. For West Africa, where agriculture, infrastructure, and energy systems are increasingly threatened by climate volatility, her work provides data-driven frameworks to balance sustainability with industrial development.By shaping global climate policy discussions and influencing how international climate finance is allocated, Denton’s work affects billions of dollars in adaptation funding. Her scholarship underscores that climate resilience is not only an environmental concern but a macroeconomic imperative.3. Dr. Ibiagbani ‘Ibi’ Max-Harry (Ghana) — Redefining Hormone Control in Diabetes Research

Dr. Ibiagbani ‘Ibi’ Max-Harry earned her Bachelor of Engineering in Biomedical Engineering from All Nations University College in Ghana, graduating as Best Graduating Student (summa cum laude). She later completed her PhD in Cell and Molecular Biology at Ohio University, where she investigated the role of parathyroid hormone-related protein (PTHrP) in pancreatic islet biology.Her research demonstrated that specific nuclear domains of PTHrP are essential for pancreatic islet development, calcium signalling, insulin secretion and glucose homeostasis. By clarifying a molecular architecture that sustains endocrine balance, her work expands diabetes research beyond insulin replacement toward deeper cellular regulation and beta-cell protection.With diabetes affecting more than 500 million people globally, such mechanistic insights carry implications for pharmaceutical innovation and public health strategy. Now an Instructor of Introductory Biology at the Massachusetts Institute of Technology (MIT), Max-Harry combines cutting-edge research with educational leadership, integrating AI tools and active learning methods to prepare the next generation of scientists.4. Dr. Abasi Ene-Obong (Nigeria) — Genomics and Precision Medicine

Dr. Abasi Ene-Obong Abasi holds a master’s degree in human molecular genetics from Imperial College London and a PhD in Cancer Biology from Barts and The London School of Medicine and Dentistry in England. He founded 54gene to address a major gap in global biomedical research: the underrepresentation of African genomic data in drug discovery and clinical trials.

African populations contain the highest levels of genetic diversity globally, yet remain significantly underrepresented in pharmaceutical databases. Ene-Obong’s work seeks to generate high-quality genomic datasets from African cohorts, improving disease-marker identification and enhancing precision medicine outcomes.As global biotech industries increasingly rely on genetic data to develop targeted therapies, African inclusion becomes both a scientific necessity and an economic opportunity. His work highlights how research infrastructure and data sovereignty can reposition Africa within global biomedical innovation chains.

5. Prof. Rose Leke (Cameroon) — Immunology and Vaccine Research

Professor Rose Leke, affiliated with the University of Yaoundé I, is an internationally respected immunologist whose work has advanced malaria research and vaccine development. She has served on World Health Organisation advisory committees and contributed to shaping immunisation policy frameworks across Africa.Her research into immune responses in malaria-endemic regions has informed vaccine trial protocols and strengthened research ethics and regulatory standards. Beyond laboratory science, she has mentored generations of African researchers and strengthened clinical trial capacity across the continent.In a post-pandemic global landscape where vaccine equity and infectious disease preparedness remain urgent priorities, Leke’s career demonstrates the importance of embedding African expertise in global health governance and biomedical research.
