Nutrition Obesity Research Center

NORC Director: Samuel Klein, MD

The Washington University Nutrition Obesity Research Center (NORC) activities enhance our understanding of the basic and clinical aspects of nutrition in the prevention, etiology, pathophysiology and therapy of nutrition-related diseases. Since its inception in 1999, the NORC has served as a nucleus for the growth and development of nutrition and obesity research at Washington University. The NORC has four core facilities including: Adipocyte Biology Molecular Nutrition Core (ABMN), Animal Model Research Core (AMR), Biomolecular Analysis Core (BMA), and Clinical Science Research Core (CSR).

The NORC is focused around three major interactive Program Themes: 

  • Obesity: Pathophysiology, Complications and Therapeutics
  • Nutrient Metabolism in Health and Disease
  • Growth, Development, and Aging

The overall goals of the NORC are to support these themes by: 

  • Stimulating innovative, interdisciplinary research and attracting new and established investigators to the field of nutrition and obesity by providing state-of-the-art, cost effective Core Research Laboratory services, exposure to leading edge research, critical feedback on ongoing research at our research conferences, access to specialized training, and support from our Pilot and Feasibility Program
  • Improving the training and education of students, house-staff, postdoctoral fellows, faculty, and allied health personnel in clinical nutrition/obesity and in nutrition/obesity research
  • Supporting and enhancing clinical nutrition and weight management services
  • Stimulating and promoting community outreach activities in nutrition and obesity in the greater St. Louis Metropolitan area

NORC Cores

The NORC Cores provide outstanding technical services and assist investigators in areas of research including isotope tracers, mathematical modeling, rodent models, and mass spectrometry. The four NORC research cores are as follows:

Adipocyte Biology and Molecular Nutrition (ABMN)

Animal Model Research (AMR)

Biomolecular Analysis (BMA) 

Clinical Service Research (CSR)

Accessing NORC Services:

Access to NORC services is open to all investigators. Though, in times of high demand, priority will go to Washington University investigators who are also members of the NORC. Any grant/project for which you wish to request services will need to be registered and approved prior to receiving services.
