He specialises in genomics and other omics of African populations using approaches such as genome-wide association studies (GWAS), polygenic risk score analysis and Mendelian randomisation. He co-led the first major GWAS of cardiometabolic traits in Africa and led the first GWAS of kidney functions in continental African populations. 

Dr Solomon Carter Fuller – Dr Fuller was a neuropathologist from Liberia, instrumental in our current understanding of Alzheimer’s Disease. In 1911 Fuller was the first to suggest that amyloid plaques and neurofibrillary tangles could be significant biomarkers for the study of Alzheimer’s. It has been said that his contributions to our understanding of the disease were so significant that were it not for the insistence of the esteemed psychiatrist Emil Kraepelin that it be named after his student Alois Alzheimer, the disease would have been named after Dr Fuller.

Alma Levant Hayden – Potentially the first African American scientist to work in the US Food and Drug Administration (FDA) after being hired in the 1950s, Hayden was an expert in spectrophotometry. Her work showed that the alternative cancer medication Krebiozen was actually just creatine, proving that the expensive scam was not a real anti-cancer therapeutic. 

Professor James E K Hildreth – One of the most influential HIV researchers in the world, Dr Hildreth’s lab identified the adhesion protein LFA-1 as playing a direct role in HIV infection.
