Role:Principal Scientist
Focus of Research:
  • Fish genetics
  • Molecular ecology and eco-genotoxicology
  • Marine Biodiversity and conservation

I graduated in fisheries science from College of Fisheries, Panangad, completed my masters’ degree in Mariculture from CMFRI, Kochi and carried out doctoral studies at University of East Anglia, UK.  I worked intensively on reef corals of Gulf of Mannar and Palk Bay with a view to gain insights into their biodiversity, taxonomy and ecology.  The effect of genotoxic chemicals on aquatic ecosystem and the role of sex in shaping evolutionary adaptations were studied using matrix population modeling in Artemia.  Presently my research is focused on population genetics of fishes and its relation to climatic fluctuations in the Indian ocean.
