I am serving as Scientist F in the Microbiology and Fermentation Technology Department (MFT) at CSIR‑CFTRI, India, where I lead multidisciplinary research at the intersection of metagenomics, fermentation science, and functional foods. My work focuses on how food‑derived glycans and microbial metabolites shape gut–liver and gut–brain axis signaling, with an emphasis on mechanistic pathways that influence immunity, metabolism, and neurobiology. My group has identified and characterized several novel enzymes from metagenomic libraries, including a polygalacturonase that generates pectic oligosaccharides capable of modulating mucosal immunity and influencing bidirectional gut–brain communication. I have authored reviews on extremozymes in food processing, histamine signaling and IL‑33–mast cell regulation in allergy, and diet–microbiome interactions, contributing to a deeper mechanistic understanding of how gut microbiota regulate immune and inflammatory pathways. My current research advances fermented foods and postbiotic formulations designed to regulate metabolic and immune pathways, We are trying to address the questions • What is the effect of prebiotics and dietary fibers supplementation on structure and functional dynamics of gut microbiome? • Elucidation of mechanism of pectin derived oligosaccharide in prevention of allergic disease
