I am interested in understanding the neurobiological mechanisms of food intake control and addiction. Using multi-level approaches in rodent models, my research explores the neural circuits, neuropeptide function, gut-brain interaction, and intracellular signaling pathways that contribute to the control of feeding and addictive behaviours.
