Research Interests

  • Aquaculture
  • Aquaculture sustainability and development of new production technologies to improve sustainable healthy seafood production
  • New nutritional strategies for improvement of aqua feed sustainability and performance
  • Aquaculture disease management, enhancement of host immunity and delivery of health solutions through feed

Current Research Projects

  • Development of feeds and feeding programs to maximize aquatic animal health and growth. Evaluation of new ingredients which can improve aquafeed  sustainability and performance.
  • Aquaculture systems ecology and dynamics focusing on microbial community structure and function. Interactions between natural productivity, feeds and fish/shrimp performance. Effects of waste production and improving system efficiencies.
  • Penaeid shrimp pathology and immunology with an emphasis on viral and bacterial disease. Development of new technologies for delivery of health benefits through feeds.
  • Risks and benefits of seafood consumption with an emphasis on developing better aquaculture products which enhance human health while avoiding potential risks from contaminants in the diet or in the environment.
