Genomics Applied to Aquaculture
We develop genomic resources (e.g. genome assemblies) and apply omics methods for applications in aquaculture, including to characterize and diagnose disease agents and better understand their evolution and transmission, to study fish immune responses, and to establish associations between genomic variation and commercially-important trait variation.

Bayesian phylogeny of salmonid alphavirus genomes built from an 11,681 bp alignment and analyzed in BEAST2 using the best fit nucleotide substitution model (TIM2 + G4), a relaxed molecular clock model, tip-dating, and a coalescent Bayesian Skyline population model. A discrete phylogeographical analysis was performed using ancestral reconstruction with branch colors indicating the estimated geographic location of each node. Statistical support for key nodes is indicated by posterior probability values in bold, and the ancestral location probability in brackets. From Gallagher et al. 2020. Front. Microbiol.
