Fish Physiology and Biochemistry, Aquaculture
I am broadly interested in a wide scope of fish physiology and biochemistry. A major portion of my research is in the area of aquaculture nutrition, with emphasis on linking dietary lipids/proteins and physiological/biochemical processes. My students were among the first in the world to characterize and demonstrate the extensiveness of polyunsaturated fatty acid biosynthesis in freshwater carnivorous teleost species. More recently, research in my lab has led to the proposal of a new family of elongases in teleosts. I also work extensively on the role of unsaturated fatty acids during embryonic development, using zebrafish as a model. My work has contributed to the establishment of a novel feeder-free zebrafish embryonic stem cell line.

My current research interest is in
1. Polyunsaturated fatty acid biosynthesis in aquatic organisms, with specific interest on the role and regulation of the fatty acyl desaturase and elongase enzymes.
a. Fundamentally, I am keen to understand how these enzymes substrate-specificity in aquatic organisms, which allows them to thrive in their respective niche.
b. I also investigate the function of these genes during zebrafish development.
c. From an applied perspective, I would be keen to link the activities of these enzymes/genes in fatty acid nutrition of different aquaculture species.
2. The application of next generation sequencing to unravel crucial pathways and overall biology of selected aquatic species (comparative genome, transcriptome, metagenome).
3. The role of microbiota in lipid nutrition of aquatic organisms
