Charles Rotimi, a genetic epidemiologist, is the Chief of the Metabolic, Cardiovascular and Inflammatory Disease Genomics Branch and the Director of the Trans-NIH Center for Research on Genomics and Global Health. His lab is particularly interested in engaging the global communities to ensure ethnic diversity in genomics research both at the level of study participants and investigators. His scientific approach takes broader societal context into account, recognizing the need not to alienate individuals or groups from the scientific process. His lab gives particular attention to ways in which scientists document and describe the non-random pattern of human genetic variation and its link to disease risks in different populations. His is the founding president of the African Society of Human Genetics and served as its president for 10years. He successfully led the establishment of the Human Heredity and Health in Africa (H3Africa) Initiative with $76 million commitment from the NIH and Wellcome Trust (Science. Jun 20, 2014). H3Africa is creating and supporting a network of labs that are conducting leading-edge research into the genetic and environmental determinants of diseases in Africans.
