Dr. Sasha Tetu

Biography

Sasha Tetu is a Senior Lecturer in the Department of Molecular Sciences at Macquarie University. He earned his PhD from the University of Sydney, focusing on the interactions of different mobile genetic elements within bacterial genomes. Following his doctoral work, he conducted postdoctoral research under Professor Ian Paulsen at Macquarie University, where he applied molecular microbiology and ‘omics techniques to study microorganisms involved in disease and agricultural processes. Dr. Tetu completed an ARC DECRA fellowship in 2020 that investigated the effects of anthropogenic pollutants on marine bacteria, assessing how these pollutants influence population phenotypic changes and gene expression. His current research focuses on understanding the genetic basis of microbial adaptation to environmental pressures and how environmental perturbations impact microbial communities, particularly the role of mobile genetic elements in bacterial niche adaptation. Among his notable projects, he investigates the impact of human pollutants on key marine microbes and assesses the importance of bacterial primary producers in marine food webs. Dr. Tetu's work employs various microbiological and molecular techniques, including flow cytometry and metagenomics, and has led to widely acclaimed publications in notable journals.
