I graduated from University College London with a BSc. (Biochemistry, First Class Hons) in 1996, followed by a post graduate teaching qualification (1997), a Masters in Public Health Nutrition at LSHTM (1998) and finally a PhD, also at LSHTM (2003). My PhD comprised a clinical trial in Ghana of low-dose maternal vitamin A supplementation to determine effects on immunity to malaria in pregnancy. In 2002 I became a staff member at LSHTM within the MRC International Nutrition Group and worked on malaria and anemia in Gambian children. In 2007 I moved to be based in Dar es Salaam Tanzania, working mostly on sickle cell disease. In 2015 I was appointed as a Professor at the School of Tropical Medicine & Global Health, Nagasaki, where I am now based. I hold a joint position as an Associate Professor at LSHTM.
