Vector-borne diseases (VBDs) are known for a long time to contribute significantly to the global burden of disease. These lead to epidemics, which upset health security and affect the socio-economy of a nation. Vectors and VBDs are all sensitive to climate, and the ongoing trend of climate change and variable weather conditions may lead to a change in the global scenario of these diseases. With changes in global climate, VBDs may shift to new regions, suitable for the pathogens and their vectors, and as such may switch to new host species. Being a parasitologist, I study parasites of veterinary importance and related diseases. My special research interest lies in understanding how vectors interact with pathogens, the effect of climate change on their ecology and epidemiology, and related sustainable control strategies.

To predict future changes in the ecology and epidemiology of the vectors and VBDs, first, we need to work on and understand the three primary entities within this disease transmission system, i.e. the pathogen, vector and the host. Secondly, we need to identify the climatic and environmental requirements of the vectors and vector-borne pathogens and the underlying cycle of events which run between them to help sustain the disease in a particular region. The global distribution of various VBDs and possibilities of spill over of these diseases between various regions and animal and vector species interests me the most. In the UK, my research was focussed on molecular and spatial epidemiology of ticks and flea-borne diseases. Further, I worked on a climate-based predictive model for the global distribution and risk of Haemonchus contortus (round worm of sheep). This model predicts the survival of worm larvae on pasture, based on the temperature and precipitation data and can help to predict the future spatial and temporal distribution and spread of H. contortus. Further, this model, along with targeted selective treatment (TST) of sheep, could help in reducing the pace at which anthelmintic resistance is developing in H. contortus and may help in sustainable sheep farming.

Currently, my lab is investigating the temporal and spatial distribution of zoonotic parasites among pet dogs in various regions of Southeast Queensland. In this project, we are collecting data from dog owners through an online survey pertaining to their knowledge of risk associated with dog parasites and their transmission into humans. Also, we are collecting dog faecal samples for microscopic and PCR analysis for various parasite eggs and oocysts. The data obtained from this survey will be analysed for determining the risk of spread of parasites among dogs as well as to humans in shared spaces and the relative risk of infection between parks.

Another study being conducted in my lab is about identifying drug resistance mechanisms in canine hookworms in Australia. The study will provide a baseline data on the frequencies of SNPs, known to confer benzimidazole resistance in animal helminths.

We have recently received an NHMRC 2021 grant looking into Targeted surveillance of major zoonotic arboviral and other vector-borne diseases in Australia using spectroscopy technology. Infectious diseases transmitted by vectors represent a significant health threat to the Australian biosecurity. Detection methods used in current surveillance of these pathogens are expensive, time consuming and require highly trained personnel. We propose to conduct a set of experiments to test the best spectroscopy technique to identify infected vectors and demonstrate its capacity as surveillance tool for vector control programs against these pathogens.

I always look forward to collaborating with fellow researchers within Australia and from different parts of the world to gain different perspectives of research of my interest.

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!

The molecular evolution of cytochrome P450 Enzymes: biological catalysts of unprecedented versatility.

Cytochrome P450 enzymes (CYPs, P450s) especially those responsible for drug metabolism in humans, are the unifying theme of the research in our lab. These fascinating enzymes are catalysts of exceptional versatility, and functional diversity. In humans they are principally responsible for the clearance of a practically unlimited variety of chemicals from the body, but are also critical in many important physiological processes. In other organisms (plants, animals, bacteria, fungi, almost everything!) they carry out an unprecedented range of functions, such as defense, chemical communication, neural development and even pigmentation. P450s are involved in the biosynthesis of an unequalled range of potent, biologically active natural products in microbes, plants and animals, including many antibiotics, plant and animal hormones, signalling molecules, toxins, flavours and fragrances. We are studying how P450s have evolved to deal with novel substrates by reconstructing ancestral precursors and evolutionary pathways, to answer such questions as how did the koala evolve to live on eucalyptus leaves, a toxic diet for most mammals.

The capabilities of P450s are only just coming to be fully recognized and structural studies on P450s should yield critical insights into how enzyme structure determines function. For example, recently we discovered that P450s are present within cells in the Fe(II) form, a finding that has led to a radical revision of the dogma concerning the P450 catalytic cycle, and has implications for the control of uncoupling of P450 activity in cells. Importantly, the biotechnological potential of P450s remains yet to be exploited. All of the specific research themes detailed below take advantage of our recognized expertise in the expression of recombinant human cytochrome P450 enzymes in bacteria. Our group is interested in finding out how P450s work and how they can be made to work better.

Artificial evolution of P450s for drug development and bioremediation: a way of exploring the sequence space and catalytic potential of P450s. The demonstrated catalytic diversity of P450 enzymes makes them the ideal starting material for engineering sophisticated chemical reagents to catalyse difficult chemical transformations. We are using artificial (or directed) evolution to engineer enzymes that are more efficient, robust and specialized than naturally occurring enzymes with the aim of selecting for properties that are commercially useful in the areas of drug discovery and development and bioremediation of pollutants in the environment. The approach we are using also allows us to explore the essential sequence and structural features that underpin all ~12000 known P450s so as to determine how they work.

Synthetic biology of enzymes for clean, green, solar-powered chemistry in drug development, bioremediation and biosensors. We have identified ancestral enzymes that are extremely thermostable compared to their modern counterparts, making them potentially very useful in industry, since they can withstand long incubations at elevated temperatures. They can be used as ‘off the shelf’ reagents to catalyse useful chemistry, such as in in drug discovery and development, fine chemicals synthesis, and cleaning up the environment. Working with drug companies, we are exploring how they can be best deployed in chemical processes and what structural features make them efficient, robust and specialized. We are also immobilizing P450s in virus-like-particles as ‘designer’ reagents that can be recovered from reactions and reused. To make such processes cheaper and more sustainable, we are using photosynthesis to power P450 reactions for clean, green biocatalysis in microalgae.

Ongoing Projects

Three PhD positions available in 2023-2025

Project 1: Unification of selection and inheritance informs adaptive potential for generations to come (Applications open in 2023; CLOSED)

Natural selection acts on phenotypes and produces immediate phenotypic effects within a generation. In this short-term process, some phenotypes are more successful than others. Use of single traits for selection analysis could generate opposing outcomes and cannot predict how selection operates on an organism. In contrast, multivariate selection in trait combinations utilizes the attribute of functional integrations to reveal how selection works in a multi-dimensional trait space. Selection is an important force driving evolution but not equal to evolution; the latter leads to changes in genetic variation. Only through assessment of the evolutionary responses of phenotypes can we understand the transmission of such selection from one generation to the next. How does selection occurring within a generation affect evolution across generations? In the project, we aim to address the question by unifying the two processes to forecast evolutionary potential in relation to selection. To that end, we partition genetic variance into components based on an experimental design, employ experimental evolution to estimate additive genetic variance-covariances (G) on quantitative scales and evaluate G-matrix evolution. We eventually hope to elucidate how populations subjected to artificial selection move along evolutionary trajectories and whether there are genetic constraints making the fitness optimum evolutionarily inaccessible.

Project 2: Genetic and ecological bases of shoot branching divergence across Arabidopsis species-wide accessions (Applications open in 2024)

Spatial patterns of genetic variation are shaped by environmental factors, topological features, and dispersal barriers. As a result, we often can identify population genetic structure stratified by geographic locations or ecological niches, the drivers of population isolation by distance or the environment, clinal genetic variation over space in alignment with gradually varying environment gradients, and adaptive genetic variation in relation to environmental variables. At the ecological level, assembly rules uncover the coordination of phenotypic traits along environmental clines. Tradeoffs between traits represent the consequence of environmental filters and reflect adaptation to environmental heterogeneity. For example, three fundamental adaptive strategies are delineated by a CSR theory, that is, Competitors, Stress-tolerators, and Ruderals. As such, ways of genetic and phenotypic assemblage over space and throughout time point to a role for natural selection driven by spatially varying environmental conditions to maintain genetic variation that confers natural variation in phenotypes. In this project, we focus on an important agronomic trait – shoot branching – due to its important contribution to the overall shoot architecture of a plant and being a potential target for yield optimization. We aim to dissect features of the genetic architecture of the trait and to reveal its relationships to environmental conditions. We integrate geographic, environmental, and genomic data from the 1001 Arabidopsis Genomes Project, coupled with the branching phenotype measured in selected accessions and then forecasted for the rest of the 1001 accessions using machine-learning models, to investigate the ecological relevance and genetic underpinnings of branching divergence across the Arabidopsis species-wide accessions. Our study has implications for enhancing our understanding of the genetic and ecological basis of shoot branching divergence and the potential for generating novel knowledge for improving phenotypic predictability.

Project 3: Dimensionality, modularity, and integration: Insights from the architecture features of pan-genomes, pan-transcriptome, pan-epigenomes, and pan-chromatin (applications open in 2025) Application Portal ALSO ACCEPTING EXPRESSION OF INTEREST FROM INTERNATIONAL APPLICANTS

Organisms are functionally integrated systems, where interactions among phenotypic traits make the whole more than the sum of its parts. How is a suite of traits assembled into an adaptive module? How is an intramodule rewired to form a regulatory network? What is the persistence and stability of a module under exposures to perturbations triggered by altered interactions between the response to disparate environmental conditions or between the responses of multiple traits to the same environment? What constrains modules to vary independently, reflecting the integration and canalization of evolutionary trajectories? In this project, we utilize a compilation of pan-genomes, pan-transcriptome, pan-epigenomes, and pan-chromatin resources of Arabidopsis thaliana to uncover how dimensionality, modularity, and integration are organized at different omics levels including genetic polymorphisms, structural variants, RNA isoforms, expression abundance, epigenetic imprinting, and chromatin accessibility. Ultimately, we apply such functional elements to multivariate genomic selection, in the hope of enhancing multilayered omics-enabled prediction.

Prof Tim Mahony joined QAAFI’s Centre for Animal Science in October 2010, after 15 years of conducting research projects with the Queensland Government. He obtained his PhD from James Cook University in the area of molecular microbiology. During 2001 and 2002, Prof Mahony was a visiting professor at the University of Saskatchewan.

Research interests

Dr Mahony’s research interests are in the area of molecular virology revolving around improving viral disease control in production animals such as cattle and poultry. His group is characterising the molecular interactions between invading pathogens and the subsequent host responses with the goal of developing new vaccines and diagnostic technologies. A key component of this work includes improving the basic understanding of the molecular mechanisms that underpin and drive viral virulence and evolution. Next-generation sequencing has been used to sequence the genomes of herpesviruses and adenoviruses from a variety of species including, cattle, chickens, marsupials, horses, and crocodiles. Prof Mahony’s team is also investigating the role of virally encoded microRNAs in virulence, replication, and disease development. His group was one of the first in the world to apply bacterial artificial chromosome infectious clone technology for the efficient manipulation of herpesviruses that have large DNA genomes. These strategies are also being exploited to understand viral gene function and the development of vaccines.

Currently, Prof Mahony is researching risk factors that protect and predispose feedlot cattle to developing bovine respiratory disease (BRD). He is also leading the development of new vaccines for BRD and cattle tick infestations. Prof Mahony has also led the development of new vaccine delivery technologies for the poultry industry targeting the application of in ovo strategies. Prof Mahony research into improving animal health is increasing industry productivity, food safety, and consumer confidence in food products and he is keen to explore collaborations with other scientists in this area.

Prof Mahony has a strong interest to work with post-graduate students and has supervised a number of post-graduate students from Australia and overseas. These projects have covered research areas in molecular virology, animal health, vaccine development, and pathogen-host interactions.
