Research areas

Human microbiome

Our bodies are home to a vast ecosystem of microorganisms including bacteria, archaea, fungi, viruses, and bacteriophages that make up the human microbiota. These microbes and their collective genetic material, known as the microbiome, influence a wide range of physiological functions: they aid in nutrient production and absorption, help in the development and regulation of our immune system, fight off potential pathogens, and even influence our mood and mental health. While distinct microbial communities exist throughout the body, the gut microbiome has gained particular attention in recent years given its link to several diseases including inflammatory bowel disease, metabolic disorders and cancer. Like other ecosystems, exploring how inhabitants of the human microbiome influence (and are influenced by) their environment is key to understanding their role in host health and survival.

Here, we use cutting-edge technologies to study the human microbiome in the context of health and disease. By integrating meta-omic approaches including metagenomics, metatranscriptomics and metabolomics with powerful bioinformatic tools developed by our team, we can provide accurate and comprehensive characterisation of these communities at unprecedented resolution.

We are particularly interested in inflammatory bowel disease, including the subtypes ulcerative colitis and Crohn’s disease, and the neurodegenerative disorder Parkinson’s disease. Our current research aims to answer important questions about the microbiome function in human health, including their distinct role in these conditions.

Marine symbiosis

Microorganisms represent important components of both free-living and host-associated marine ecosystems, performing vital functional roles that maintain global ocean health and productivity. Australia’s marine estate is facing extensive and rapid change as a result of global climate change, yet our understanding of the diversity, structure, and function of the primary biotic determinants of ocean health, the marine microbiome, remains limited.

We are studying marine microbial communities using an integrated genome-centric approach to explore both functional and phylogenetic diversity. By focusing our research on Australia’s most iconic ocean habitat, reef-building corals of the Great Barrier Reef, we aim to provide detailed insights into the beneficial functional roles of the microbiome in coral health and resilience.

Microbes and the global carbon cycle

Microorganisms have several important roles in global carbon and nutrient cycles. Our understanding of these processes, and the microorganisms responsible, is critical to our comprehension and response to Earth’s rapidly changing climate.

We will apply meta-omics and single cell visualisation methods to characterise the microbial communities responsible for the metabolism of methane and short chain alkanes (ethane, propane and butane), which are potent greenhouse gases ubiquitous in the environment.

A key environment for this work will be permafrost wetlands, which contribute a tenth of global methane emissions and contain a quarter of the global soil carbon.

Microbial bioinformatics

The study of microbial ecology is almost always data-heavy since it involves the study of microbes in the context of their microbial community. Bioinformatics provides the statistical analysis, exploratory approaches and scalable computational toolsets necessary to study the structure and function of microbiomes from a wide range of environments. Given the increasing size of metagenomic data being generated, bioinformatic advances are required in order to fully realise the potential of this data and explore understudied components of microbial ecosystems.

Our work will advance the science of microbial bioinformatics by developing novel bioinformatic techniques and implementations that will be widely applicable in microbial ecology.

Our facilities

Housed within the Translational Research Institute, the Centre for Microbiome Research is uniquely positioned amongst top researchers and world-class facilities to drive scientific discovery and translational research. We have access to a purpose-built research environment for the study of microbial ecology and evolution using state-of-the-art molecular biology and computing facilities. Its location at the Princess Alexandra Hospital (PAH) provides access to clinical cohorts, which is critical for our work on the human microbiome.


Long read sequencing

Advancements in high-throughput next-generation sequencing technologies have revolutionised genomic research. These technologies largely replaced single gene approaches by enabling paralleled sequencing of short fragments of DNA that are then pieced together into a continuous genomic sequence, offering a high-throughput and low-cost option to sequence whole genomes.

However short reads of DNA can be insufficient, with a limited ability to resolve complex and repetitive regions of the genome and the complicated task of genome reconstruction. In contrast, long-read sequencing technologies directly sequence single molecules of DNA, thus improving de novo assembly, mapping certainty, and identification of transcript isoforms and structural variants.

We aim to become the first certified service lab in Australia to offer a long-read sequencing service on the PromethION 24. This technology provides improved efficiency and accuracy over existing DNA sequencing applications, including:

  1. Direct sequencing of native DNA and RNA with capacity for real time analysis
  2. No restrictions on read length, capable of high-throughput sequencing of ultra-long reads
  3. Ability to sequence up to 24 flow cells at a time, and generate up to 200Gbp of data per flow cell

Flow cytometry

We have a dedicated high-speed cell sorter for microbial samples with the ability to sort single particles (using 96/384 well plates) and bulk populations. It is housed in a Class II biosafety cabinet and is therefore OGTR approved to handle human samples. With a dedicated operator with expertise in environmental microbiology, we are able to help with project design and development of new assays to target populations of interest.

Confocal microscopy

Confocal microscopy is an optical imaging technique for increasing the resolution and contrast of a micrograph. By capturing multiple two-dimensional images at different depths in a sample we are able to reconstruct three-dimensional structures (a process known as optical sectioning) within an object. This technique allows exploration of microbial habitats and the observation of microorganisms in situ with an unprecedented accuracy.
