Doctor Zhiguang Qiu

Dr Zhiguang (Galaxy) Qiu joined the Hawkesbury Institute for the Environmental as a Postdoctoral Research Fellow in January 2018. He is an environmental microbiologist interested in microbial communities/functions associated with hosts and their variation respond to environmental changes. He is currently involved in a SRA project ‘A Novel Polyphasic Framework to resolve Yellow Canopy Syndrome Paradox’ investigating ‘yellow cane syndrome’ (YCS) on sugarcane, evaluating the effect of interactions between resident microbiome(s) and YCS on soil health and manipulating this information for YCS management.

He obtained his PhD in Biological Science at University of New South Wales in 2017 under supervision of Professor Peter Steinberg, Dr Ezequiel Marzinelli and Dr Alexandra Campbell. During his doctoral studies, he investigated microbiomes associated with marine seaweeds by using next-generation sequencing technologies to determine the composition, abundance and functions of these microbes under different host and environmental conditions. He has a set of skills including amplicon and shotgun sequencing technologies to characterise microbiomes associated with seaweeds and their functional metagenomes, bioinformatics pipelines to create presence/absence and relative abundance matrices for analyses of seaweed-associated microbiomes, and various of statistical methods to determine the effect of variation on microbiome affected by environmental stressors. Finished projects including: i) Characterise microbial communities and functions associated with different host conditions, ii) Predict the variation of microbiomes associated with kelp driven by climate change, especially in future environmental scenarios, iii) Interpret microbiomes associated with kelp in different habitats caused by anthropogenic activities, and iv) Explore potential pathogens in the microbiome that causing algal disease by conducting inoculation experiment using bacterial strains isolated from sick kelp.

Zhiguang has a BArgo (2008) and MArgo (2011) in Ocean University of China and Yellow Sea Fisheries Research Institute, China, respectively.
