In 2011 she received a New Year’s Honour (Officer of New Zealand Order of Merit) for services to health. Her clinical work is in high risk pregnancy especially preeclampsia and fetal growth restriction. A key research interest is the epidemiology of stillbirth, in particular the role of maternal sleep practices.
