He received his PhD in nutrigenomics from the University of Lausanne Switzerland in 2005. During his post-doctoral positions at The Scripps Research Institute in San Diego California and the French National Institute for Health and Medical Research (INSERM) in Paris France, Dr. Mutch began to study human obesity using an approach integrating global metabolite profiling (metabolomics), gene expression (transcriptomics), and genomics. In January 2009 he joined the University of Guelph to establish a nutrigenomics research program focused on studying the interactions between genes, dietary fats, and inflammation, and how this contributes to the development of obesity-related complications.
