Biographical details

Christine Roberts (MBBS, FAFPHM, DrPH ) is a medical epidemiologist with clinical experience in obstetrics, paediatrics and neonatology. In 2006 she was awarded an NHMRC Senior Research Fellowship (Level A), and in January 2007 took up the position of Director of Clinical and Population Perinatal Health Research in the Kolling Institute. Her main research interests are in making better use of routinely collected data to evaluate and improve care in pregnancy and childbirth, assessing population health data quality, and clinical trials in pregnancy care and maternal outcomes.

In 2012, Christine was awarded a further NHMRC Senior Research Fellowship (Level B), as well as one of three inaugural NHMRC Elizabeth Blackburn Fellowships, introduced to foster the career development of female scientists excelling in biomedical, clinical and population health research. Christine has over 200 peer-reviewed publications, has received over $16m in peer-reviewed funding, and is a regular presenter at national and international conferences.

In addition to Christine’s research activities, she has supervised or co-supervised over 40 students completing research Masters or PhD degrees. She also teaches regularly for the University of Sydney, including participating in the Hoc Mai teaching program in Vietnam. Christine has been a member of several international and local committees, including the International Health Data Linkage Network, the Expert Standing Panel for the Commonwealth’s Medical Services Advisory Committee, the NSW Tiered Maternity Network Working Group, and she is the chair of the Reproductive, Maternal and Child Health Key Research Area in the Northern Sydney Local Health District.
