We work on early host-microbe interactions, with specific emphasis on human epithelial innate immunity and bacterial biofilms. The human epithelial surface is continuously exposed to microbes and acts as the first line of defense against infections. Arrays of Pattern Recognition Receptors on epithelium associated cells discriminate between commensal vs. pathogens microbes; and produce endogenous antibiotics like defensins against pathogens. The latter develop biofilms, which use complex Quorum signalling to generate virulence factors that can outcompete these immune determinants. The balance between these competing early host-microbe forces often determine the outcomes of infections. In this context we use novel biofilm models, innate immune arrays, transcriptomics and mass spectrometry based metabolomics to investigate these domains in collaboration with leading hospitals. As part of this we are currently part of the National Neonatal Sepsis Research Consortium (DBT), one of the largest research programs in India in collaboration with AIIMS, TSHTI, IGIB, NII and ICGEB.
