My research work focuses on translational aspects of type 2 diabetes and other aging-related metabolic diseases, from identification and validation of novel drug targets, development of high throughput screening assays, to preclinical testing of potential therapeutic compounds in animal models. Our work has recently identified a critical missing link between mitochondrial dysfunction in aging and the onset aging-related metabolic diseases, including diabetes, heart failure, stroke, and Alzheimer’s diseases. Using genome-wide synthetic lethal screening, we have also identified a family of novel regulators of phospholipid trafficking between ER and mitochondria. We are currently characterizing their function in regulating the onset of aging-related diseases.

Related Diseases: Mitochondrial dysfunction, cardiolipin remodeling, aging, metabolic diseases.

Techniques: Molecular cloning, confocal imaging analysis of mitochondrial dynamics, enzymatic assays, signal transduction, mitochondrial respiration, transgenic and knockout mice, metabolic phenotyping, echocardiography, glucose tolerance, insulin tolerance and animal surgery
