Research Interests: Dr. Bradbury’s research interests center on uptake of fatty acids into cells and the function of fatty acid transporters, especially in the setting of obesity and hepatic steatosis. Understanding these processes and molecules will help us describe the processes whereby excess fats accumulate in adipose and liver tissue, leading to obesity, diabetes and fatty liver disease of various types. This knowledge could lead to better treatments for disorders and interventions that may prevent their development.
