Kieran Clarke
PhD
Emeritus Professor of Physiological Biochemistry
Since 1991, Professor Kieran Clarke has worked at the University of Oxford on the effects of diet on energy metabolism in human heart, brain and skeletal muscle. Specifically, her interest in physical and cognitive function has led to the development of a fourth food group, a ketone ester called ΔG®, that improves endurance exercise in athletes and could be used for the management of common metabolic diseases, such as type 2 diabetes.
Before Oxford, Professor Clarke worked as a postdoctoral fellow at Harvard University Medical School and as a research scientist at the NRC in Ottawa, Canada.
