Yaw Bediako is an immunologist and the CEO of Yemaachi Biotech, an Accra-based immunogenomics company focused on diversifying precision oncology. Under his leadership, Yemaachi has positioned itself as a key contributor to African cancer research by leveraging the continent’s genetic diversity to identify novel biomarkers and therapeutic targets.
A landmark achievement of his tenure is the 2025 launch of the African Cancer Atlas (TACA) in partnership with Roche. This consortium aims to sequence 15,000 genomes from 7,500 African cancer patients, creating one of the world’s most comprehensive genomic datasets to address the historic underrepresentation of African populations in global drug discovery and diagnostic development.
Dr. Bediako’s leadership has attracted global support, including a $25 million Cancer Grand Challenges award as part of the SAMBAI consortium to investigate cancer inequities. He has also been recognized as one of the 100 Most Influential Africans and a Bloomberg New Economy Catalyst, highlighting his role in advancing precision medicine across the continent.
Through strategic partnerships with organizations such as Bio Usawa, Dr. Bediako is helping bridge the gap between genomic research and the development of locally relevant oncology solutions, ensuring that the future of precision medicine is inclusive and accessible.
The 100 CEOs featured here reflect the diversity and complexity of modern oncology leadership.
