Dr. Klein’s primary research involves the use of both basic and clinical research tools to evaluate cellular, regional, and whole-body substrate metabolism to test physiologically and clinically relevant hypotheses in human subjects in vivo. His laboratory is specifically focused on understanding the pathophysiological alterations in metabolic function associated with obesity in people and the mechanisms for weight-loss induced benefits in ameliorating obesity-related metabolic abnormalities.
