Metabolic Regulation Lab

We study adipocytes (fat cells) and adipose tissue. In recent years, our focus has been on the molecular control of differentiation, activation and metabolism of brown adipocytes. Our interest in brown adipose tissue biology derives from the striking ability of brown adipocytes to counteract obesity and insulin resistance in experimental animals and the observation that active brown fat is present in many adult humans. Ongoing projects revolve around metabolic regulation and signal transduction. Our aim is to uncover novel regulatory mechanisms through which brown adipose tissue can be exploited therapeutically.
