Dr. Tarrant’s program of research focuses on improving maternal and child health outcomes and has resulted in an extensive publication record on a range of subjects, including breastfeeding and maternal and childhood vaccinations. A strong focus on health promotion and disease prevention in the context of women and children’s health underpins all of Dr. Tarrant’s work. Her research has not only helped to improve health outcomes but has also impacted health service delivery for new mothers, specifically as it relates to improved breastfeeding support in the immediate postpartum period. Dr. Tarrant’s work will continue to combine epidemiological studies to further explore and understand the determinants of maternal and child health behaviours with individual and community-focused interventions to support and promote breastfeeding and vaccination programs.

Dr. Tarrant’s study methodologies have included large longitudinal cohort studies, population-based cross-sectional studies and intervention studies designed to inform and influence public health policies and perinatal health-care services. Her research has put a much-needed spotlight on maternal health and has received more than $2.0M (CAD) in funding. Dr. Tarrant has recently completed a trial of an intervention to improve maternal influenza vaccine uptake and has an ongoing study investigating the effect of breastfeeding on postpartum glycemic control in women diagnosed with gestational diabetes.

Dr. Tarrant has extensive teaching experience at both the undergraduate and graduate level including Bachelor of Nursing, Master of Nursing, and Master of Clinical Pharmacy programs. She has taught courses in public health nursing, epidemiology, population health, and educational assessment methods. She previously received the Li Ka Shing Faculty of Medicine Teaching Medal for Excellence in Teaching from the University of Hong Kong.

Dr. Tarrant has successfully supervised over 20 research post-graduate students and has published more than 70 articles in peer-reviewed journals.
