Senior Research Fellow (Biostatistician)

Jill works in the Division of Sciences as a biostatistician. She collaborates with health researchers across the Division but is housed in the Department of Human Nutrition. She has qualifications in maths and biostatistics and also holds a PhD in Human Nutrition and Medicine. She currently co-supervises all Master of Dietetic students as principal investigator of the SuNDiAL project – a nationwide survey of diet, nutrition, and lifestyle.

Jill also works part-time in the Biostatistics Centre (Division of Health Sciences).
