My research is focused on the molecular and cellular signaling mechanisms associated with energy metabolism in skeletal muscle and adipose tissue across different species. This research is aimed at improving animal production traits and meat quality, and at developing strategies to reduce the prevalence of obesity and diabetes. I am interested in epigenetic modifications and interactions of genetic background, diet and development on regulation of selective lipid deposition, insulin resistance and adipocyte turnover. Specific endeavors include 1) Elucidating mechanisms underlying differences in food intake and adiposity in chickens selected for high or low body weight and 2) investigating the use of flavonoids as anti-obesity/diabetic compounds through improving insulin resistance in adipose tissue and skeletal muscles.
