Microbial ecology, Bacterial systematics and Metagenomics.
Our research group studies prokaryotic diversity from different habitats with a special focus on Biodiversity hot spots. The microbial community structure is characterized using culture-dependent and -independent metagenomics approaches based on 16S rRNA gene tag sequencing. We have been involved in studying the surface of intertidal macroalgae and mangrove environments as specialized niches for bacteria. In the past few years we have described several novel taxa from these environments and have also applied genomic approaches to rectify their taxonomy. Current research projects 1) Bioprospecting and taxonomic studies of marine microorganisms in search of novel anti-infectives. 2) Use of genomic approaches for deciphering taxonomic intricacies in bacterial taxa.
