Research Interests
Diseases of human metabolic health where energy balance is disordered are significant medical and socioeconomic problems. Meaningful intervention requires an understanding of the processes involved. My research aims to investigate how disorders of energy balance can result from disruption of the pathways that control how we eat, how we metabolise fuel and how we store excess energy in tissue. The basis of these studies comes primarily from studies of human disease, including rare genetic forms of obesity and larger population-based genetic studies.
In collaboration with colleagues in the IMS (O’Rahilly, Yeo) my work aims to gain a more mechanistic understanding of how pathways highlighted by these human genetic studies can malfunction and result in disorders of energy balance and metabolism
Our current understanding of the central control of appetite has relied heavily upon mouse models and I combine murine genetics and whole animal physiological studies to address these issues, in particular how signals from peripheral organs are integrated within the brain to change appetitive behaviour. Through an evolving interaction with colleagues at CRUK , I am also interested in determining how resources and skills developed in the study of obesity can be employed to understand the body composition and metabolic phenotypes seen in cachexia.
