Lisa Houghton is a Emeritus Professor in the Department of Human Nutrition with research interest in community and international nutrition.
Professor Lisa Houghton joined the Department of Human Nutrition in 2008. Lisa completed her undergraduate and MSc training at the University of Guelph, Canada, her clinical dietetic training at McMaster Health Sciences, and her PhD in Nutritional Sciences at the University of Toronto. Prior to arriving in New Zealand, Lisa was an Assistant Professor at Acadia University, and was a Research Associate at The Hospital for Sick Children, Canada, and the Premature Infant Nutrition group at Abbott Laboratories, USA. She is a member of American Society of Nutrition and the International Society for Research on Human Milk and Lactation.
Lisa Houghton's research is focused on the assessment and health consequences of micronutrient deficiencies in “at risk” population groups, with particular expertise in maternal and young child undernutrition. Current topics of investigation include nutritional assessment of infants, young children and mothers in Indonesia, Kenya and India; investigation of the influence of infant and young child feeding practices on diet quality, gut microbiota, growth and morbidity; assessment of the impact of a complementary feeding home-fortification strategy using a desiccated beef powder on the growth and development of young children; and, development of a field friendly exclusive breastfeeding biomarker tool.
