Sherly Tomy. Ms. Dr
Designation : Principal Scientist
Discipline : Animal / Fish Genetics And Breeding
Division : Nutrition, Genetics and Biotechnology Division
Specialization : Molecular Endocrinology
Research areas:
  • Molecular Endocrinology regulating reproduction of crustacean and finfish.
  • Development of strategies to induce maturation of captive stocks.
Brief profile:

After taking masters in Fish & Fishery Science (Mariculture) in 1997, Ph.D. in Fish & Fishery Science in 2002 and a post-doctoral experience in Taiwan (2004 to 2009), I have been working in CIBA since September 20009 on molecular endocrinology of penaeid shrimps and finfish. I have worked on the molecular reproductive endocrinology of finfish and crustacean. I have contributed to the understanding of the molecular pathway regulation vitellogenesis and development of induce maturation protocols alternative to eyestalk ablation in penaeid shrimps. I have interest in understanding the neuroendocrine pathways regulating reproduction and its application to fish culture.
