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 and fluoride in vulnerable groups of the population, such as 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 was a member of a multi-disciplinary group that measured the environmental literacy of students at the University of Otago. More recently, Professor Skeaff has led a team that 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. Her Inaugural Professorial Lecture can be viewed here.

Professor Skeaff leads the Metrics and Management theme of Food Waste Innovation Otago, which measures food waste, develops reduction strategies, applies innovative technology, and works to modify producer and consumer behaviour. She has been involved in measuring food waste in primary production, retail, and food service (eg, universities halls of residence and aged care). Research in Food Waste Innovation builds on Professor Skeaff's interest in sustainable nutrition.

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. In addition to being a long-standing academic at the University of Otago, Professor Skeaff has held or been appointed to a number of national and international expert groups. Professor Skeaff served as the President of the Nutrition Society of New Zealand for six years and is the vice-chair of the trans-Tasman Expert Working Group for Iodine that is reviewing the Australian/New Zealand Nutrient Reference Values for Iodine. She is a member of a World Health Organisation external expert group working to revise guidance on Iodine indicators. Professor Skeaff plays a key role in the governance of the Oceania Nutrition Leadership Platform (https://www.onlp.org/), serving as the Chair. She is on the Editorial Board of the journals Maternal and Child Nutrition and Frontiers of Nutrition. In 2018 she gained national recognition with an Ako Aotearoa Tertiary Teaching Excellence Award and in 2022 was the OUSA best postgraduate supervisor of the year.
