 Research interest

My research interests are focused on using the state-of-the-art "genomics" technologies and experiments to study and characterize various physiological processes in non-model species. I use high throughput omics and bioinformatics approaches to study gene networks/pathways that regulate different physiological traits at genomics, transcriptomics, post-transcriptomics and proteomics levels. My projects include but are not limited to utilization of genomic approaches to examine and enhance fish production traits with particular interest in muscle growth and quality.
