Epigenetic regulation of insulin resistance and energy expenditure in obesity and type 2 diabetes
The research in the laboratory focuses on identifying novel targets and developing new tools for the treatment of obesity and diabetes. We are particularly interested in understanding epigenetic regulation of energy expenditure and insulin resistance. We have developed several animal models to ask questions regarding how epigenetic signatures are altered in obesity and type 2 diabetes, and how the altered epigenetic signatures regulate insulin sensitivity and energy metabolism. Another direction of the laboratory is directly related to transnational medicine. We are developing new tools for drug delivery to metabolic organs such as fat tissue and liver. The goal is to increase metabolic rate selectively in these organs for treating obesity and diabetes.
