RESEARCH

My research expertise is in aging, insulin resistance and exercise physiology. My research program in metabolic/endocrine gerontology, is devoted to exploring the effects that aging has on numerous metabolic and cellular processes, and relevant to the patho-genesis of age-related diseases such as diabetes, obesity, and sarcopenia. My main clinical interests are (i) pathogenesis, prevention and treatment of diabetes in the elderly; (ii) molecular mechanisms underlying sarcopenia of aging; and (iii) effects of exercise on glucose and lipid metabolism at the whole-body and cellular levels. We conduct our research in human subjects, rodents, and cell cultures.
