Our primary research interest is the neurobiology of appetite with particular emphasis on understanding how food intake, food choice and feeding behavior is controlled.  One major focus is to determine the effects of endocrine and metabolic signals, such as ghrelin, on brain networks that control food intake, food choice and associated feeding behaviours. These brain networks include pathways involved in energy balance, reward and emotion. We are interested in the role of the gut-brain reward axis in normal physiology and in disease mechanisms that lead to obesity and overeating disorders.
