RESEARCH

Aging is the primary driving force for the development of obesity, type 2 diabetes, cardiovascular, neurodegenerative, and other aging-related diseases. However, the underlying molecular mechanisms remain poorly identified. 

Dr. Yuguang (Roger) Shi’s lab focuses on translational aspects of aging-related metabolic diseases using molecular, cellular, metabolic, and transgenic approaches. Our work has recently identified a critical missing link between mitochondrial dysfunction in aging and the onset of various aging-related diseases, paving the way for the development of novel treatment for these pathogenic conditions. 

We are also uncovering novel signaling pathways that regulates glucose-sensing by pancreatic beta cells, since a loss of glucose responsiveness by pancreatic beta cell is a major pathological event that triggers the onset of type 2 diabetes. The lab is recruiting graduate students and postdoctoral fellows.
