Dr Domingos is a Research Scientist at DAF QLD and holds an Adjunct Research Fellowship within the CSTFA. His research focuses on the development and incorporation of improved hatchery techniques, with focus on the reproduction, domestication and selective breeding programs of tropical aquaculture species. He is particularly interested to develop genetically improved barramundi and cobia strains for a sustainable and profitable Australian aquaculture industry.

Dr Domingos has recently assembled and published first draft genome of the Australian barramundi. He is currently working to understand the hermaphroditic sex change in the species, so that hatchery managers can have a better control over the breeding process. Dr Domingos has identified DNA methylation of several sex genes during adulthood to be a key epigenetic mechanism silencing male genes and awakening female genes. He also coordinates R&D projects towards (i) the mapping and identification of gene variants associated with superior growth performance, (ii) the use of RNA interference technology (RNAi) to "switch-off" counterproductive genes and (iii) teasing out genotype by environment (GxE) interactions in commercially important traits.
