Research Focus

The research focus is to understand the cellular mechanisms and neural pathways by which macronutrients are detected in the intestine, and to determine the way in which these processed are altered in pathology and disease, such as long term changes in the macronutrient content of the diet, obesity, inflammatory bowel disease.
