My major research interest is in investigating the microbial diversity associated with extreme, pristine and other habitats for taxonomic novelty and industrial applications (especially Bioenergy, Petroleum Biotechnology and Bioremediation). My group works on collecting samples from a variety of extreme and pristine habitats including (but not limited to) volcanic mud, deep subsurface high temperature oil reservoirs, submarine methane hydrate sediments, high altitude lake sediments, etc. We document the bacterial and archaeal diversity associated with such environments using metagenomics.. Extremophiles such as thermophiles, halophiles, barotolerant and other microorganisms are isolated and novel taxa are documented by adopting the polyphasic identification approach. Microbial cultures, in isolation or as consortium, are used to develop technologies in the field of bioenergy, petroleum biotechnology, bioremediation or production of valuable enzymes/ biomolecules. Microbial metabolism underlying such industrial application is investigated using whole genome, transcriptome and proteome analysis.
