The obesity-metabolism component includes 34* researchers, 33 nurses and research professionals, as well as 46 graduate students and postdoctoral fellows. In Canada, this component is considered one of the most significant groups working in obesity. In addition, the Institute represents a remarkable environment for clinical research in this field, while 740 cases of bariatric surgery are done each year. Université Laval, which oversees the Institute’s bariatric surgery group and researchers, ranks 18th (Science Watch, Thomson Reuters, 2010) worldwide among over 30,000 research institutions in terms of the number of scientific publications on obesity. This achievement is the result of a multi-faceted approach that includes nutrition, behaviour, surgery, molecular biology, applied human genetics, physiology, etc. applicable to human and animal, whether for tissue and cellular models. Basic research within the component focuses on multiple aspects of obesity triggers and complications. Clinical research has grown remarkably in recent years and involves numerous collaborations both within the component and with the other research components.
