My present research focus is mainly on drug discovery for novel compounds of therapeutic value for major human ailments from coastal living resources. Coastal organisms like coral reefs are of economic and environmental significance and often been subjected to anthropogenic and natural perturbations causing great concern today. Since ocean is the last frontier for mankind to exploit natural resources of all kind, It is very much imperative to understand the systems like behaviour, biology and evolutionary genomics of corals and associated organisms towards its interacting environmental variables thoroughly before judicious exploitation. My research over a decade focused on understanding the coastal ecosystem how human activities and natural factors affect the coral reef ecosystem in the Gulf of Mannar and adjacent Palk Bay, besides continuous monitoring of the changes encountered by these corals and associated organisms.
