About me

About me

I am an independent Campus Fellow at the National Centre for Biological Sciences, Bangalore, India. Before joining NCBS, I worked as a CSIR-Quick Hire Fellow at National Institute of Oceanography, Goa. I did my PhD from Ecole Normale Supérieure, Paris under the supervision of Dr. Chris Bowler. During my PhD, I worked on biogeographical distribution of marine diatom communities collected during the Tara Oceans expedition using high throughput -omics data sets. My doctoral experience and a quest to unfold various ecological questions cemented the foundation for my research at NCBS.

Research interests: Ecoinformatics, Environmental genomics, DNA metabarcoding, Marine microbial diversity, Blue Biotechnology

Planktons are a vital part of the Earth's life support system, providing half of the oxygen generated each year on Earth by photosynthesis and lying at the base of marine food chains on which all other life in the ocean depends. Despite that drawing, a global picture of their biodiversity, community structure and ecological determinants remains a grand challenge. As a computational biologist involved in ecological research, the possibility that interests me, and that is the central topic of my study, is to understand their unexpected biodiversity. Presently, I am working on community structure and assembly of major protistan lineages, dominating the world oceans, by integrating genomics and environmental data. 

Alongside this project, I am also interested in investigating the microbial eukaryotic community structure in the oligotrophic and oxygen-depleted zones in the Arabian Sea (AS) and Bay of Bengal (BoB) using metagenomic analysis. There are a lot of mysteries about the OMZs - and particularly the BoB and AS OMZs, which differ from the Eastern Upwelling Margins.

Recently, I joined National Advisory Board Committee of Marine Ecology Researchers Club (MERC) and Citizen Marine Science Program (CMSP) at Centre for Climate Change Studies (CCCS), Sathyabama Institute of Science and Technology, Chennai, Tamil Nadu. Our main goal is to build a network of action-oriented researchers to discuss topics related to India’s coastal and marine ecosystems, their functional ecology and associated biodiversity conservation.
