My international roles include being a Council Member of both the International Union of Nutritional Sciences (IUNS) and the Federation of African Nutrition Societies (FANUS). I sit on the Professional Advisory Committee of HarvestPlus and am a board member of the educational foundation the Nestlé Nutrition Institute. I am a Fellow of the Academy of Medical Sciences and a Member of the US National Academy of Science.
Our research covers a broad portfolio of nutrition-related disease with an emphasis on driving Africa-specific insights and interventions. Within this, my own chief interests are in the interplay between iron, infection and immunity, and on the impact of a mother's pre-conceptional diet and nutritional status on the emerging fetal methylome and downstream epigenetic influences on later-life diseases.
