Role:Senior Scientist
Focus of Research:
  • Taxonomy and biology of fishes
  • Monitoring of marine ecosystem and biodiversity using underwater census method
  • Ecology and conservation biology  of vulnerable/threatened resources  

I am a professional graduate in fisheries science and my area of specialization is aquatic environment management. During my post-graduation, I worked on the removal of heavy metal contaminants from aquatic environment using algal biomass and my doctoral research is about the species diversity in trawl by-catch along Tuticorin coast and its economic valuation. At present as a researcher, I have been a part of the Central Marine Fisheries Research Institute (ICAR) since 2012 and I am currently involved in specific projects on marine biodiversity and fishery biology. I have deposited specimens (either as first or new record) in the designated marine repository and further I am studying the impact of over fishing on marine ecosystem and subsequent loss of biodiversity. As part of a team, I have carried out under water assessment of coral reefs and associated fauna from Lakshwadeep Islands and Gulf of Mannar. In the near future, my research interests are about the ecology and conservation biology of marine ornamentals and impact of exotics in marine ecosystem.
