I am a comparative and environmental physiologist based at the University of Queensland. My research focuses primarily how the environment constrains the physiology of invertebrates, fish, amphibians and reptiles. I have a highly diverse research program that incorporates fundamental, curiosity-driven research and increasingly, a more applied research agenda in the emerging field of conservation physiology. Conservation physiology explores the responses of organisms to anthropogenic threats and attempts to determine the ecophysiological constraints dictated by current conditions and future environmental change. My research interests encompass the general areas of osmo- and ion-regulation, digestive and thermal physiology, environmental drivers of physiological function (specifically immune function and disease susceptibility) and animal performance in anthropogenically modified environments.
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!
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.

The Vukovic laboratory investigates how brain function is sculpted and influenced by the immune system. Specifically, we examine the role of brain’s main resident immune cell population (i.e. microglia), as well as various peripheral immune cells, on learning and memory in mice. We are interested in defining the contribution of immune cells to such higher cognitive tasks, including for neuroinflammatory conditions where learning and memory deficits can occur, e.g. following traumatic brain injury, cancer treatment, and ageing. We have established an array of genetic and pharmacological tools alongside robust behavioural assays to directly probe the function of these immune cells in both the healthy and diseased brain. The ultimate goal of our work is to link cellular and molecular events to altered behaviour, and to harness the brain’s intrinsic regenerative potential for stimulating optimal cognitive function.
A neuroimmunologist, Dr Vukovic received her PhD in 2008 from The University of Western Australia after working on the repair of injured nerve cell connections. She joined QBI in 2009 to work in Professor Perry Bartlett’s laboratory as a Postdoctoral Research Fellow, before being awarded a Queensland Government Smart Futures Fellowship to continue her research into the importance of adult neurogenesis for behaviour and how microglia influence this process in ageing. Dr Vukovic demonstrated that microglia can exert a dual and opposing influence over adult neurogenesis (the birth of new neurons) in the hippocampus under different physiological conditions, namely exercise and ageing, and that signalling through the chemokine receptor, CX3CR1, critically contributes towards this (Vukovic et al., 2012, J Neurosci). Dr Vukovic also generated novel evidence that ongoing neurogenesis in the adult hippocampus is critical for new learning but does not play a role in memory recall (Vukovic et al., 2013, J Neurosci).
Dr Vukovic was awarded an ARC Discovery Early Career Researcher Award (2015-2018) and was jointly appointed as a group leader by the UQ School of Biomedical Sciences (SBMS) and QBI in 2015. She heads the Neuroimmunology and Cognition team investigating the interactions between the brain and the immune system in health and disease.
Currently, the group is working on three main projects:
Identification of microglia-derived molecules that support neuronal survival and stimulate neural stem/progenitor cell expansion
Characterisation of immune cell contribution to changes in neuronal connectivity
Immune cell responses to cancer treatment, and their effect on learning and memory
