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.

I completed my PhD, supervised by Dr. Jan Engelstaedter, investigating host shift dynamics of parasites within a host clade. In this project I am was interested in understanding the long-term dynamics and consequences of host-shift dynamics, while taking into account the evolutionary relationships between host species. I was interested in identifying predictable patterns in the distribution of pathogens using statistical and mathematical modeling.

Currently, I am a postdoctoral researcher working at the University of Queensland under Dr. Christine Beveridge. I will be creating computational models of plant hormone signalling in order to make predictions on the phenotypic outcomes of plant species.

Dr. Laura Grogan is a qualified veterinarian, Senior Lecturer in Wildlife Science, Chair of the Wildlife Disease Association Australasian section, and Leader of the Biodiversity Health Research Team (https://www.biodiversity-health.org/) - a collaborative multiple-university research group focused on finding sustainable solutions for the most challenging threatening processes currently affecting biodiversity.

Dr. Grogan has a background in research on wildlife diseases, ecology and conservation. She's particularly interested in investigating the dynamics, relative importance, and impacts of infectious diseases among other threats affecting wildlife across both individual and population scales, to improve conservation management. While she works across taxa and methodological approaches, her main study system currently involves the devastating amphibian fungal skin disease, chytridiomycosis, where at the individual scale she focuses on the pathogenesis and amphibian immune response to the disease, untangling the roles of resistance and tolerance in defense against infection. At the population and landscape scale she explores mechanisms underlying persistence in the face of endemic infection, focused on the endangered Fleay's barred frog. She also studies population and infection dynamics of chlamydiosis in koala using a mathematical modelling approach, exploring the relative benefits of different management approaches. In addition to working on amphibian and koala diseases, Laura is a keen birdwatcher and wildlife photographer, and supervises projects in other wildlife-related fields.

You can find out more about her research team here: www.biodiversity-health.org. Dr. Grogan has been awarded around $1.3 million in research funding since 2018. In late 2019 she was awarded an Australian Research Council Discovery Early Career Researcher Award (DECRA; DE200100490), worth $426,742. This project, titled "Understanding infection tolerance to improve management of wildlife disease", commenced in late 2020. Dr. Grogan was identified as one of the four top-ranked science DECRA awardees by the Australian Academy of Science’s 2020 J G Russell Award, and was also recipient of the highest award of the Wildlife Disease Association Australasia Section with their 2019 Barry L Munday Recognition Award.

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.

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.
