Dr Gal Winter is a microbiologist studying microbial ecology in human and plant environments. For the past four years Gal has been working as a lecturer and Course Coordinator for the Bachelor of Biomedical Sciences at the University of New England. Gal has won several awards for excellence in teaching and research and has published her research outcomes in renowned professional journals. In 2008, Gal moved from Israel to Australia to chase her professional dream of working on microbial food biotechnology and her personal dream of living the Australian lifestyle. She received an international PhD scholarship from the University of Western Sydney and worked in collaboration with the Australian Wine Research Institute on wine fermentation, graduating her PhD in 2013. She then commenced a postdoctoral fellow at the University of Queensland, working on microbial biotechnology for the production of value-added chemicals.

Research Interests

I am fascinated by the “microbiome revolution”, that is the mounting evidence that suggest that the collective microorganisms inhabiting the human body (i.e. the microbiome) have a significant influence on physical and mental health. I  am particularly interested in understanding the role of the gut microbiome in the diagnosis and treatment of depression. This research has the potential to impact on the health and wellbeing of Australians, with as many as 1 in 6 people being diagnosed with depression throughout their lifetimes.I further apply the principles of microbial diversity to other environmental systems through academic and industry collaborations. A recent collaboration includes a study of the plant root microbiome in hydroponics systems. this project is part of the Future foods systems CRC.
