Evolutionary and ecological genomics of marine invertebrate animals.
My lab's research is driven by a fascination with genomes that carry within them endless, brilliant solutions forged by evolution over millions of years in response to a constantly changing ocean. We tap into this to learn how the genomes of coral reef invertebrates and their bacterial symbionts interact with each other, and with the environment, throughout their life cycle. We study these gene-environment interactions in evolutionary and ecological contexts, using genomic, molecular and cellular approaches combined with behavioural ecology in natural populations.
We work often with embryonic and larval life history stages of indirect developers, as these stages are crucial to the maintenance and evolution of marine populations. Our current focus is around larval settlement and metamorphosis in the holobiont of the coral reef demosponge Amphimedon queenslandica. In recent years, our work has extended to functional genomic approaches to identify noval ways to control the coral reef pest, the Crown-of-Thorns starfish.
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 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, wildlife photographer and artist. She supervises projects across wildlife-related fields (predominantly vertebrates).

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.
