I am a maternal, perinatal and child health researcher with twenty years’ experience in global health. My background is as a clinician and epidemiologist. I have experience working professionally across a number of countries including UK, Malawi, Kenya, Mozambique, The Gambia, India, Bangladesh, Ethiopia, Guinea-Bissau, Uganda and Ghana.


Faculty of Epidemiology and Population Health
Department of Infectious Disease Epidemiology


Centre for Maternal Adolescent Reproductive & Child Health (MARCH)
Health in Humanitarian Crises Centre


I am passionate about teaching, mentoring and supporting the development of early-career researchers including the supervision of both PhD and MSc students.

I am programme co-director for MSc Public Health for Development. I co-organise the current issues in Safe Motherhood and Perinatal Health module and am a tutor on the Research Design and Analysis, Study Design and Applying Public Health Principles in Developing Countries modules.


My research areas include

  • Improving measurement of birth outcomes across various data platforms including household surveys, Health Management Information Systems and Civil registration and Vital Statistics systems.
  • Global estimates of vulnerable newborns including stillbirths, preterm birth, low birthweight, small-for gestational age, neonatal morbidity and congenital disorders
  • Stillbirths: Ending preventable deaths and improving care for affected women and families
  • Impact of ill-health, nutritional, social, environmental and climate exposures starting in-utero and vulnerability at birth on women and children’s physical and mental health, and children’s neurocognitive developmental trajectories.
