I joined the Department for Health as a Lecturer in 2014 and my research interests are nutrition and metabolism.
Studying postprandial metabolism gives insight into the future risk of developing chronic diseases such as type 2 diabetes, cardiovascular disease and dementia. I am embarking on a programme of research to explore the interactions between nutrition and exercise and the effects on metabolic health, particularly in the postprandial state. By understanding how metabolically active organs such as muscle, adipose and the liver interact within whole-body human physiology in response to nutrition and exercise, more precise interventions can be developed to target specific health conditions.
In a sports performance context, I have performed research in highly trained cyclists and triathletes, studying how nutrition can influence metabolism during endurance exercise and in recovery, and how respiratory physiology affects performance. Additionally, I am the Nutrition Section Editor for the International Rugby Board (IRB) Science Network.
I completed my PhD in Human Nutrition and Metabolism in 2013. My thesis covered topics including nutrition, exercise, metabolism and appetite. During my PhD studies I also spent time at the Department of Metabolic Medicine at Imperial College London, to work under Prof Sir Steve Bloom. Following this, I undertook a post-doc which used 13C and 1H magnetic resonance spectroscopy (MRS) to investigate the effects of nutrition on liver and muscle metabolism during exercise.
