Dr Sheila Skeaff
Dr Skeaff conducts research on the iodine status of sub-groups of the population, including children and pregnant women. Dr Skeaff also undertakes research on the environmental literacy of university students and sustainability as it applies to food and nutrition.
Dr 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. Dr Skeaff has expertise in the assessment of trace elements, with particular emphasis on iodine. She conducts research on the iodine status of sub-groups of the population, including children and pregnant women. Dr Skeaff is also interested in elucidating the consequences of mild iodine deficiency on normal growth and development, including cognition. She has collaborations in Malaysia, India, Australia, the USA and Switzerland. Dr Skeaff is also part of a multi-disciplinary group developing a tool to measure the environmental literacy of university students. She is also conducting research on sustainable foods and diets.
Dr Skeaff teaches mainly in the area of micronutrients. She coordinates the paper HUNT 223 (Minerals, undernutrition and health) and NUTX 401 (Principles of Human Nutrition). She also teaches into a number of other undergraduate papers in Human Nutrition.
