Mission

The mission of the Energy Metabolism Laboratory (EMET) is to explore determinants of energy regulation throughout adult life and contribute to reducing the obesity epidemic both in the United States and worldwide. Studies are conducted on both nutrition (factors influencing energy intake and expenditure) and eating behavior.  New interventions are being created to help individuals and groups manage their weight in ways that are easier and more sustainable.

Lab Objectives


1. Develop and test new lifestyle interventions for easier and more sustainable weight management across the lifecycle.  Randomized controlled trials are ongoing in military families and worksites.

2. Lead an International Obesity Consortium of scientists from nine countries (Brazil, China, Ghana, Guinea-Bissau, India, Kuwait, Italy, Singapore, U.S.) and conduct studies to understand the diverse cultural and other barriers to successful weight control in different locations.  Once barriers are identified, the knowledge will be used to create interventions to be tested and refined.

3. Conduct metabolic studies and clinical trials of dietary composition and meal timing to improve dietary recommendations for health, weight management and cognitive enhancement across the lifecycle.

4. Continue to improve methodology for studying weight management, including the development of improved software for monitoring daily food intake.

Senior Scientist
Research focus: Dietary, behavioral and cultural determinants of body fatness, and development of behavioral programs for weight loss and prevention of weight regain. In addition, new formulations of foods for prevention and treatment of malnutrition across the lifecycle, in particular to reduce susceptibility to obesity and improve cognition.
