After over a decade as a medical doctor, ultimately specialising in treating children with cancer, I decided to focus on the aim of prevention of disease through healthy eating. Completing a PhD in genetics inspired my interest in how genes are turned on and off (epigenetics) and understanding the microbiome (the trillions of microbes which live in our digestive systems), which ultimately fuelled my interest in nutrition. There is still much research to be done, but with the scientific information already available, there are healthy choices that you could be making now which mean a rich array of tasty nutritious food, that may improve the quality of your life and reduce your future risk of disease.

I studied medicine at Trinity Hall, University of Cambridge and University College London. I have completed a PhD in cancer genetics from UCL and hold a postgraduate Membership of the Royal College of Paediatrics and Child Health. I have an accreditation for Applied Human Nutrition from The University of Cambridge. I no longer practice as a doctor, but instead provide nutritional consultancy, and lecture on culinary science and nutrition. I am a Registered Nutritionist with the Association for Nutrition.
