Research Focus


My collaborative clinical research focuses on the metabolic alterations in type 2 diabetes and obesity, particularly those implicating protein metabolism. My colleagues have demonstrated that whenever insulin resistance of glucose metabolism occurs, that of protein anabolism does as well. We have also shown, by increasing protein (amino acid) supply, that the resisitance can be overcome. In a recent fMRI study we showed that brain activity in cognitive control regions, rather than hormones controlling energy balance, plays a critical role in weight loss. We are presently providing deep metabolic phenotyping in a multi-omic study of the heterogeneity of type 2 diabetes.
