After my PhD at King’s College London (formerly Queen Elizabeth College), I worked in the food industry for a short while and then moved to the Institute of Food Research, Norwich, initially as a Senior Research Scientist and latterly as Head of the Nutrition Division and Programme Leader for Micronutrients. In 2006 I was offered a personal chair in the School of Medicine, Health Policy & Practice UEA and moved to UEA in early 2007.
