Professor Sheila Skeaff

MSc(Guelph) PhD (Otago)

Sheila Skeaff Thumb 2016Email sheila.skeaff@otago.ac.nz

Professor Skeaff conducts research on the trace element status of the population, with a particular focus on iodine. Professor Skeaff also undertakes research on the environmental literacy of university students and food literacy in children.

Professor Skeaff has an MSc in Nutritional Biochemistry from the University of Guelph (Canada) and a PhD in Human Nutrition from the University of Otago. She conducts research on the iodine status of sub-groups of the population, including children and pregnant women. Professor Skeaff is also interested in elucidating the consequences of mild iodine deficiency on normal growth and development, including cognition. She is a member of a multi-disciplinary group that measures the environmental literacy of students at the University of Otago. She also conducts research on sustainable foods and diets. Recently her team developed and validated an online questionnaire to measure food literacy in children, which is currently being used to evaluate the impact of school gardens on food literacy in New Zealand children.

Professor Skeaff is a steering committee member of Food Waste Innovation, a University of Otago Research Theme which measures food waste, develops reduction strategies, applies innovative technology, and works to modify producer and consumer behaviour.

Professor Skeaff served as the President of the Nutrition Society of New Zealand for six years and sits on the trans-Tasman Expert Working Group for Iodine that is reviewing the Australian/New Zealand Nutrient Reference Values for Iodine. She also plays a key role in the governance of the Oceania Nutrition Leadership Program, serving as Deputy Chair. She is on the Editorial Board of the journal Maternal and Child Nutrition. In 2018 she gained national recognition with an Ako Aotearoa Tertiary Teaching Excellence Award.

Professor Skeaff coordinates and teaches the paper HUNT 141: Understanding Human Nutrition.
