Dr Kathryn Erica Bradbury

BSc MSc PhD Otago.


I was awarded my PhD in Human Nutrition, from the University of Otago, in 2013. I then spent 5 years in the Cancer Epidemiology Unit, Nuffield Department of Population Health, at the University of Oxford. In Oxford I worked as a nutritional epidemiologist on large cohort studies: the Million Women Study, the European Investigation into Cancer and Nutrition (EPIC), and the UK Biobank. Broadly, I am interested in examining the role of diet in the development of cancer, cardiovascular disease and other non-communicable diseases. I also have a special interest in researching the health and nutritional status of vegetarians, and the health and environmental impact of eating meat.

Research | Current

I have several current research interests. I am currently working on the nutritional component of the MENZACS study (the Multi-Ethnic New Zealand study of Acute Coronary Syndromes) - a cohort of patients with Acute Coronary Syndrome. We have measured diet and taken blood samples for lipidomic analysis. I am also investigating the environmental impacts of New Zealand household food and beverage purchases.

Postgraduate supervision

2020 - Anna-Marie Rattray (Master of Public Health). Household purchasing of folic acid fortified breads by socio-demographic characteristics.

Areas of expertise

I have particular expertise in traditional and web-based dietary assessment methods, nutritional epidmiology (including prospective analyses of large cohort studies), biomarkers of nutritional status (including folate), blood lipids, the role of diet in the development of gastrointestinal cancers, and vegetarian nutrition.
