The major focus of our research effort concerns the mechanisms of
obesity-induced metabolic diseases such as type 2 diabetes, which is a
serious disease that affects 8.3% of the population in the United
States. Currently we are using molecular biology, biochemical, and cell
biology approaches as well as tissue-specific transgenic and knockout
mouse models to identify and characterize key molecules involved in the
regulation of glucose metabolism and energy homeostasis. Particularly we
are interested in how obesity leads to adipocyte dysregulation and how
adipose tissue dysfunction affects whole body energy homeostasis. It is
our hope that better understanding of the mechanisms underlying the
crosstalk between adipose tissues and other tissues will generate
important information for the development of new therapeutic drugs for
the treatment of obesity-associated disorders such as Type 2 diabetes,
cancer, and aging.
