Research interests are infectious disease epidemiology, with a particular focus on maternal and newborn health. Work is national and international, with a strong interest in health in low-resource settings, and in-particular East Africa.

Anna is a Senior Program Officer, Maternal Immunization Product Development and Surveillance at the Bill & Melinda Gates Foundation. She was previously Professor of Public Health in Warwick. Anna trained in medicine, and specialized initially in paediatrics. She then developed research interests in neonatal infection, and in particular Group B Streptococcus, working at the KEMRI-Wellcome Trust Research Centre in Kenya, through the University of Oxford. She completed her clinical training in public health, and developed a programme of work at the London School of Hygiene & Tropical Medicine, setting up a new Gates-funded research programme in Eastern Ethiopia, in collaboration with Haramaya University, to investigate the specific causes of death in children. She also took up a Wellcome Trust Career Development Fellowship to investigate the infectious causes of perinatal death in Kenya and Ethiopia. Anna subsequently led the research programme of the UK Public Health Rapid Support Team, developing multi-disciplinary research projects in outbreaks of infectious diseases in low-resource settings, and supporting capacity development in the context of outbreak response. During the COVID-19 pandemic she seconded to the Joint Biosecurity Centre where she led an interdisciplinary team to provide public health analytics on disease prevalence, health care, vaccine impact and variants, to inform the national response. She has since returned to her interest in perinatal infection, and in particular work on preventing Group B Streptococcal disease through maternal vaccination, leading on a program of work at the Bill & Melinda Gates Foundation.
