Dr Hongwei (Jason) Liu has over 7 years' progressive experience in Microbiology and Microbial Ecology research, in particular in functional profiling of plant and soil microbiomes. He was awarded PhD degree in Agricultural Science at the University of Queensland in 2017 under the supervision of Professor Peer Schenk, Dr Paul G. Dennis and Dr Lilia C. Carvalhais. Through extensive training during his research, he now possesses the skills in a range of culture-independent methods for plant and soil ecology, in particular next generation sequencing techniques and microbial community profiling (16S and 18S rRNA amplicon sequencing). Other methods include qPCR and qRT-PCR functional and phylogenetic marker genes, T-RLFP, and Microresp®.
Plants are associated with diverse microbial communities that influence their health and nutrition. These organisms are known collectively as the plant microbiomes and could be used to more sustainably maintain or enhance global food security. His previous research aimed to testing those factors that influence soil and plant-associated microbiomes and exploring ways to manipulate them for a more sustainable agriculture. He was among one of the most productive PhD students in Schenk's lab, and successfully finished several major projects for his PhD degree, leading to 8 published papers in 2016 and 2017. Those finished projects include (i) effects of plant signalling pathways (jasmonic acid and salicylic acid) on wheat-associated microbiomes, (ii) effects of strategic tillage on microbial properties of continuous no-till soils in eastern-Australia, (iii) how wheat-associated microbiomes correlate to crown rot disease symptom at stems, and (iv) effects of 1-aminocyclopropane-1-carboxylate (ACC) and salinity on soil microbial properties and soil microbiomes.
Dr Liu now is a Postdoctoral Research Fellow in the institute (joined in 2017). He is currently involved in a multi-disciplinary project "Supporting Healthy Bees and Healthy Crops" that is aimed to better understand and protect Australian bees. He will undertake a combined methodologies approach to reveal both, the structure and function of honey bee microbiomes during plant and soil interactions.
