Research Profile

My research focuses on investigating how long-term consumption of palatable high-fat, high-sugar foods causes alternations in the gut-brain neural circuitry and the endogenous function of the gut-vagus-brain axis to promote cardiovascular malfunction, diabetes and obesity. By utilizing a combination of neural circuit mapping, in vivo live cell imaging, chemogenetics and optogenetics approaches, my research aims to unravel how ensembles of neural networks that receive anatomical and functional inputs from the gut are dysregulated in metabolic disease states.
