My aquatic animal health research program focuses on fish health and disease issues within warmwater aquaculture production systems. Using an applied approach, our lab aims to translate research findings from the bench to the production facility. Specifically, my fish health research focuses include:
  • Host-pathogen interactions
  • Mechanisms of virulence in emerging fish pathogens and the fish immune response
  • Nutritional aspects of fish health (including alternative feed ingredients and feed-based therapeutants/immunostimulants)
  • Aquaculture vaccine design, optimization, and delivery strategies
  • Characterization of the immune response and pathogen susceptibility in up-and-coming fish species with production potential
