My research work is focused around improving the measurement and global estimation of perinatal conditions (including preterm birth, low birthweight, small-for-gestational-age, stillbirths, congenital abnormalities and neonatal morbidity and associated long term consequences) as part of the Every Newborn Action plan to end preventable newborn deaths and stillbirths. I was a leading author on Lancet papers regarding national and global rates of preterm birth (2012) and stillbirths (2011 and 2016). I played a central role in the Lancet Every Newborn series, Every Newborn Action Plan (2014) and Lancet Ending Preventable Stillbirths series (2016). I have also coordinated novel estimates on congenital conditions and disability after neonatal complications. 

More recently, I co-ordinated the EN-INDEPTH study aiming to inform in improvements in measurement of pregnancy outcomes including stillbirth and neonatal deaths in household surveys. My current work is focused on closing the gap in epidemiological  understanding of the impact of gestational age and birthweight on perinatal and child survival through the Vulnerable Newborn Measurement Collaboration.

In addition to the advancement of the global perinatal epidemiology knowledge base, I am interested how this knowledge can be integrated in policy and practice to ensure that every baby counts and am excited about improving the use of data in policy and programmes to improve the health of mothers and babies worldwide.
