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

Associate Professor Skeaff has an MSc in Nutritional Biochemistry from the University of Guelph in 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. Associate 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 is also conducts research on sustainable foods and diets. Recently her team has developed and validated an online questionnaire to measure food literacy in children, which is currently being tested throughout New Zealand.

Associate Professor Skeaff is the current President of the Nutrition Society of New Zealand and is the Chair of a 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. She serves on the Editorial Board of the journals Nutrients and Maternal and Child Nutrition.

Teaching

Associate Professor Skeaff coordinates and teaches the paper HUNT 223 (Minerals, Undernutrition and Health) and NUTN 401 (Principles of Human Nutrition).
