Brief profile:

After taking a master in Fish Production and Management in 1992, Ph.D. in Fishery Microbiology in 1997 from College of Fisheries, Mangalore, India and post-doctoral experience during 2003 to 2009 from Baylor College of Medicine, Houston, Texas, USA, I have been working at CIBA, Chennai, India since January 2010 on Aquatic Animal Health related aspects. I have worked on disease monitoring of L.vannamei farms and hatcheries, WSSV and host protein interaction, defense mechanism of shrimps and RNAi therapy for shrimp WSSV. I have contributed to the disease status of India due to exotic pathogens, with particular reference to AHPND/EMS, genotype related virulence status of WSSV and RNAi as a prophylactic against WSSV. I have interests in determining virulence status and pattern of spread of several aquatic pathogens, developing treatment strategy and antimicrobial resistance.

Research areas:

  • Disease diagnosis for fin fish and shellfish
  • Virulence mechanism of aquatic pathogens
  • Antimicrobial Resistance (AMR)
  • Development of treatment strategy
