Evolutionary and ecological genomics of marine invertebrate animals.

Animals evolve because their genomes need to respond to the constantly changing environment presented by both their external habitat and their internal microbial symbionts. Over evolutionary time, these different factors interact during development, when the animal body plan is being established, to generate the extraordinary animal diversity that graces our planet. In ecological time, early life history stages must detect and respond to the precise nature of their environment to generate a locally-adapted functional phenotype. Using coral reef invertebrates from phyla that span the animal kingdom, we study these gene-environment interactions using genomic, molecular and cellular approaches combined with behavioural ecology in natural populations. We work mostly with embryonic and larval life history stages of indirect developers, as these are crucial to the survival, connectivity, and evolution of marine populations. When not immersed in the molecular or computer lab, we are lucky enough to be immersed in the ocean, often in beautiful places!

Genetics of mental health (new research)

We are using the genetic model organism, C. elegans, do investigate the genetic basis of both normal and disordered behaviour. Our current interests are identifying the genes responsible for anxiety and depression as well as the genes for eating disoders and addiction. Using C. elegans as a model organism will also allow us to study gene function as it relates to behaviour.

Molecular mechanisms of phosphine resistance (other research)

Genetic mapping of oxidative stress resistance genes. The fumigant phosphine disrupts oxidative metabolism, resulting in the production of reactive oxygen intermediates. This causes the premature ageing and death of targeted pests. Insect pests of stored grain in Australia now exhibit resistance to phosphine at levels more than 200 times the normal lethal dose.

We have genetically mappedf and identified the genes responsible for phosphine resistance in tall major insect pests of stored grain. We are using a systems biology approach in the model organism C. elegans to understand the molecular basis of phosphine action. Our genetic studies have recently shown that resistance to phosphine is associated with an extension of lifespan

Invertebrate Virology

Insects are commonly infected with viruses. We study the interactions between viruses and their insect or arthropod hosts.

Viruses are obligate parasites, that is, they are completely dependent on the host cell machinery to complete their replication cycle. During infection, viruses commonly cause pathology in the host. For these reasons, viruses and hosts are in a constant evolutionary arms race. The host evolves antiviral mechanisms to prevent virus infection, while the virus adapts to overcome these host responses. Insects are ideal hosts to understand both the host response and the virus mechanisms for controlling the host.

My research group investigates the interactions between viruses and insects, primarily using Drosophila as a model. In this model we can control the genetics of both the host and the virus to tease apart the contribution of each partner to the interaction.

We discovered that a bacterium, Wolbachia, mediated antiviral protection in insects. We have several projects investigating both the mechanisms that protect the insects from virus infection and the impact of this protection on virus transmission.

Research interest: Monitoring ecosystem health of coral reefs and seagrass habitats, integrating field and remote sensing image datasets, and the developing applied cost-effective mapping and monitoring approaches. Developed approaches have been adopted as standard practice globally, making a difference in conservation of these valuable habitats. The long term monitoring studies at Heron and Moreton Bay formed the basis for the development of mapping and monitoring over time and space at local to global scale. See here major research impact

Dr T. Thang Vo-Doan is a Lecturer of the School of Mechanical and Mining Engineering at the University of Queensland. He was a postdoctoral researcher at the Institute of Biology I, University of Freiburg, Germany (2019-2023). He was also a Research Fellow at Nanyang Technological University (NTU), Singapore (2016-2018). He was awarded his PhD in Mechanical Engineering from the School of Mechanical & Aerospace Engineering, NTU in 2016. He received his M.Eng. degree in Manufacturing Engineering and B.Eng. degree in Mechanical Engineering from Ho Chi Minh City University of Technology, Vietnam in 2010 and 2008 respectively. He was awarded the prestigious Human Frontier Science Program Cross-disciplinary Fellowship (2019-2022).

He directs the UQ Biorobotics lab after joining in the University of Queensland. Current research activities of the lab focus on insect-machine hybrid robots, bio-inspired robotics, insect structures and functions, biomechanics, fast lock-on tracking, and brain imaging in untethered insects.

My research interests are centred around the structure and function of venom and silk polypeptides produced by arthropods, and their use in biotechnology and medicine. I am a Postdoctoral Fellow in the King laboratory in the Institute for Molecular Bioscience, the University of Queensland, Australia. Currently, I am investigating the composition, function and evolution of neglected insect venoms produced by assassin bugs (Hemiptera: Reduviidae), robber flies (Diptera: Asilidae) and nettle caterpillars (Lepidoptera: Limacodidae).

I have a keen interest in the evolutionary relationships that underpin symbioses, particularly those involved in plant disease. There are countless examples of how diseases have impacted on different crops throughout history, and this is an ongoing issue that deleteriously impacts food security. My research involves developing a better understanding of the epidemiology of plant diseases and pests, and delivering improved diagnostics and field management. Working with collaborators and international experts, my work involves research on a broad range of plants that are affected by bacteria, fungi, oomycetes and viruses. I have a strong interest in the biotic factors that govern soil health and the methods by which we can promote the development of beneficial microbial communities.
