RESEARCH INTERESTS

We are involved in research focusing on the molecular and genetic/genomic basis of feed efficiency and growth. Our interest is to combine classical nutrition with modern molecular techniques to understand the differences in feed efficiency and growth within the same and/or among different stains/families of channel catfish and rainbow trout and other finfishes. To explore this possibility we will study the interface between dietary manipulations, temperature, gut microbiomes, and mitochondrial functions in metabolic efficiency with growth, and possibly determine the potential role of nutrients and non-dietary factors (genetics, temperature, gut microbiome) in the molecular modulation of mitochondrial functions (protein and gene expression levels) relating to feed efficiency and growth.  
Other areas of interest include aquaculture waste management.
