Research Focus:

Kathiresan Purushothaman, with a research focus on molecular biology and genomics, has made significant contributions to understanding the Asian seabass genome. His work includes the chromosomal-level assembly of the Asian seabass genome, morpho-histological characterizations of its alimentary canal, and barcoding analysis revealing distinct species. Additionally, he has conducted proteomics and transcriptomics studies on zebrafish embryos, Asian seabass acclimated to different salinities, and the effects of pelleted feeds on Asian seabass. His diverse research spans from genetic variations in individuals and populations to exploring the intestinal mucus proteome of Atlantic salmon to counter inflammation.
