Biography

I am currently the Associate Dean Research in the Faculty of Science. Previously, I was Deputy Head of School and the Director of Research in the School of Biotechnology and Biomolecular Sciences. My research area is environmental microbiology and I specialise in uncovering Antarctica's soil biodiversity by performing discovery-based and applied research. I am passionate about integrating 'omics' with innovative cultivation methods to the isolate and describe the diversity and functional capacity of 'extreme' microbial communities. By doing so, my team discovered a previously overlooked�� carbon fixation process where�� bacteria literally ‘live on thin air’. We coined this microbial-based process ‘atmospheric chemosynthesis’ and published these findings in the prestigious journal Nature. My team also works on using microbes as indicators of soil health, for the assessment of ecosystem recovery during bioremediation and for developing site-specific ecotoxicity assessments. My future goals are to continue to challenge our understanding of the nutritional limits and the boundaries of life, while training the next generation of confident scientists.
