Research Interests:

I am interested in function and regulation of adipose tissue in aging and age-related disease. Aging is associated with redistribution of body fat with loss of subcutaneous fat and gain of visceral fat, which leads to increased risk of metabolic syndrome and cardiovascular disease (CVD). Accumulation of senescent cells in fat with aging induces the releasing of inflammatory cytokines and chemokines. I am particularly interested in elucidating the mechanisms of how preadipocytes and adipocytes in aging manipulate the function of vasculature. I am also interested in obesity induced cellular senescence, which links to the dysfunction of adipose tissue and metabolic disorder.
