Interests

Being a food and gut enthusiast, I firmly believe in the notions, “we are what we eat”, “all disease begins in the gut” and “let food be thy medicine”. Accordingly, my research interests span around understanding the host-associated microbiome and the dynamics of diet-gut-brain interface at the extremes of aging and in aging-associated metabolic and cognitive health. Specifically, our interdisciplinary lab aims at discovering novel signatures of gut dysbiosis in host metabolic diseases including obesity and type-2 diabetes and neuropsychiatric disorders including stress, anxiety and depression. Ultimately, we aim to explore how microbiome modulation with specific nutritional interventions including dietary elements, micronutrients, probiotics and prebiotics could ameliorate the pathology of these disorders.
