Optimal nutrition during pregnancy is important for healthy babies and children. My interests are focused on how maternal micronutrient status influences birth and childhood outcomes.

My long-term research goals are to use existing cohorts, in which components of maternal diet, particularly micronutrients, assessed by dietary intake methodologies or by biomarkers, are compared to pregnancy outcomes and subsequent disease risk. In addition, genotyping mother and infant will allow the assessment of the potential interaction between maternal diet, variation in genes, and outcome.

My research will include clinical trials to rigorously test these associations as well as dose response trials will to determine requirements or optimal intakes of dietary constituents during pregnancy.


Current Project
Beverly Anne Biggs and Gerard Casey (University of Melbourne) to examine examine the effectiveness of weekly iron and folate supplements in reducing anaemia in women of reproductive age in in a rural province of Vietnam.

Current Project
Antonia Shand, Peter von Dadelszen, and Sheila Innis (co-Investigators) investigation into vitamin D status in early pregnancy influences subsequent risk of pre-eclampsia (hypertension of pregnancy) in women at high-risk for this condition

Current Project
Sheila Innis (Co-Investigator) and Vancouver Public Health Dietitians to determine whether pregnant women in Vancouver receive enough vitamin D. Factors that influence vitamin D status such as ethnicity, sunlight exposure, and season will also be explored.
