Personal profile
Research interests
I am interested in human fuel use. How we get fuel from our diet, burn fuels during exercise; and store fuels when they exceed our requirements.
My research group employs a variety of methods to understand human fuel use, including indirect calorimetry, tissue biopsies and stable isotope (IV) infusion and ingestion. We use these methods across laboratory-based and free-living studies to answer basic science and practically-relevant questions.
I joined the Department for Health at the University of Bath in 2014 as a Lecturer (Assistant Professor) before being promoted to Senior Lecturer (Associate Professor) in 2017, Reader (Associate Professor) in 2020 and Professor of Nutrition and Metabolism in 2022. I am also a consultant to sports teams and industry.
In recognition of my research, I received the Julie Wallace Award 2018 from the Nutrition Society and in 2025 became one of the Inaugural Excellence in Nutrition Fellows of the American Society for Nutrition. I am an Associate Editor for the International Journal of Sport Nutrition & Exercise Metabolism.
