About me

I completed a Bachelor of Science with First Class Honours in Botany at UQ and went on to carry out a PhD on microalgal photosynthesis at the Institute for Molecular Bioscience (IMB, UQ). I then completed a postdoc at Ruhr-University Bochum, Germany on microalgal hydrogen production. I returned to UQ to develop RNA interference-based control strategies against plant pathogenic fungi and in 2018 was awarded an Early-Career Advance Queensland Industry Research Fellowship (AQIRF) to develop RNA vaccines against fungal diseases threatening Queensland crops and native plants. In 2021 I obtained a Mid-Career AQIRF to prepare RNA vaccines for application in the field.

Research focus and collaborations

My research focus is the development of environmentally-friendly RNA vaccines to protect Australian crops and native plants from aggressive fungal and oomycete pathogens including Phytophthora root rot of avocados and pineapples, and myrtle rust of native Myrtaceae species including lemon myrtle and tea tree. I am performing this work in collaboration with researchers at the Queensland Department of Agriculture and Fisheries, New Zealand Crown Research Institutes Scion and Plant and Food Research, as well as industry partners Nufarm Australia, Australian Pineapples, Howe Farming Enterprises, Greenlife Industry Australia, Kai Loa, Australian Native Products and the Australian Tea Tree Industry Association, who are helping me translate my research into a technology that can be used by Australian growers as an alternative to broad-spectrum pesticides.

Researcher biography

Dr Anne Sawyer is a molecular plant biologist passionate about the development of plant-based solutions to global problems. Her current research focus is the development of RNA sprays to protect plants from fungal pathogens. Dr Sawyer completed her PhD at the Institute for Molecular Bioscience, The University of Queensland on gene expression in microalgae. Following this, she carried out postdoctoral research at Ruhr University Bochum in Germany on microalgal hydrogen production. Dr Sawyer then returned to Australia to study RNA interference in plants and plant pathogenic fungi. Dr Sawyer has research experience in the fields of biotechnology, molecular biology, microalgal biology, synthetic biology, biochemistry and structural biology.
