I trained as a clinician in Ghana at the Kwame Nkrumah University of Science and Technology. I obtained a master’s degree in Epidemiology and a PhD in infectious disease control from the London School of Hygiene & Tropical Medicine (LSHTM). My PhD examined the role of age groups and interpersonal contact patterns in persistent vaccine-type pneumococcal carriage in rural Gambia. Before enrolling at the School, I worked on infectious diseases, including meningitis and malaria. I then joined the Kumasi Centre for Collaborative Research in Tropical Medicine (KCCR). I served as the Scientific Officer for the African Research Network on Neglected Tropical Diseases (ARNTD) and the Severe Typhoid in Africa Program (SETA) coordinator. In 2019, I joined LSHTM as a Research Fellow. Currently, I serve as a Clinical Trial Epidemiologist at the Medical Research Council Unit in The Gambia at LSHTM, coordinating a series of studies that compare a reduced-dose pneumococcal conjugate vaccine (PCV) schedule with the standard schedule.
