Dr. Ravinder Nagpal

Director: The Gut Biome Lab 

Interests

My research focuses on understanding the role of the gut microbiome in host aging-associated intestinal and neurocognitive health. The overarching goals of my research program are to discover gut ‘dysbiosis’ elements and underlying mechanisms of beneficial versus pathogenic microbes and metabolites in host physiology and to harness this knowledge to develop novel nutritional/pharmacological interventions to foster a healthier microbiome and ameliorate gut, cardiometabolic and neurodegenerative disorders including obesity, type-2 diabetes, and Alzheimer’s disease. Specifically, the ongoing research in my microbiome research lab is centered on unveiling the cellular, molecular and microecological mechanisms underlying the following:

(a) the role of gut microbiome dysbiosis and entero-septic pathobiome elements in host neurodegenerative disorders including Alzheimer’s disease.



(b) interaction of gut microbiome with specific nutritional interventions, dietary components, and pre/probiotics in context to host metabolic and neurodegenerative health.



(c) the role of maternal and neonatal microbiome elements in relation to developmental origins of health and disease.

We utilize cutting-edge and high-throughput microbiological, metagenomic, computational and preclinical models to gain comprehensive understanding of specific bacteriome, mycobiome and metabolome factors and their interactions with the host physiological system. Our lab has an extensive array of multidisciplinary collaborations with experts in gerontology, neuroscience, microbiology, nutrition/food sciences, cell/molecular biology, immunology, sepsis, and clinical care, with the principal mission to gain advanced and inclusive insights into this intricate and fascinating area of research.
