Background

I am a Newcastle University Research Fellow (NURF) working within the Human Nutrition Research Centre and Diabetes Research Group. Prior to moving to Newcastle I studied a PhD in clinical exercise physiology within the Diabetes Research Group, of the College of Medicine, and the Department of Sport and Exercise Science, at Swansea University.

My primary research interests focus on the role of exercise in the management of chronic disease, with particular interest in the facilitation of safe and effective exercise in those with Type 1 diabetes.  I also explore nutritional and insulin dose adjustment strategies to improve mealtime glucose control in both Type 1 and 2 diabetes.

I have received funding from Diabetes UK, Diabetes Research & Wellness Foundation, The Novo Nordisk UK Research Foundation, Juvenile Diabetes Research Foundation, Arla Foods Ingredients, Medtronic, Beneo Europe.

Expertise

I have conducted various nutrition and exercise projects that are published in highly esteemed clinical journals that have involved measures such as continuous glucose monitoring, exercise in high-risk patient groups, appetite regulation, postprandial glucose control, endothelial progenitor cells, gastric emptying, free-living nutritional interventions.

I am also an expert panel member for the international Type 1 diabetes and exercise education programme ‘JDRF PEAK’.
