Brief profile:

After taking masters in 1994 and PhD in 1998 I am working in CIBA since 1998 on 03-02-1998. I currently work in the division of Nutrition, Genetics and Biotechnology Division in CIBA. I have worked on the development of indigenous shrimp feed technology and development of feeds for brackishwater fin fishes, I have contributed to commercialization of shrimp and fish feeds. I have interests in the development of sustainable use of fish meal and fish oil in brackishwater feeds.

Research areas:

  • Animal/Fish Nutrition
  • Nutrient Profiling
  • Abiotic stress amelioration

Current Research Projects:

Funded By
