Summary
X-ray induced photoacoustic nanoprobe: Break depth dependency of bioimaging. This project aims to develop a nanoprobe using an X-ray excited luminescence “nanolaser” as the local light source to activate coupled responsive photoacoustic sensors. In-situ imaging of specific biomarkers at the molecular level is key to understanding their roles in physiological and pathological processes, but current imaging techniques using fluorescent probes cannot detect biomarkers in deep tissues due to shallow ....X-ray induced photoacoustic nanoprobe: Break depth dependency of bioimaging. This project aims to develop a nanoprobe using an X-ray excited luminescence “nanolaser” as the local light source to activate coupled responsive photoacoustic sensors. In-situ imaging of specific biomarkers at the molecular level is key to understanding their roles in physiological and pathological processes, but current imaging techniques using fluorescent probes cannot detect biomarkers in deep tissues due to shallow light penetration. By capitalising on the tissue penetrating property of X-rays and acoustic waves and collecting acoustic waves as the read-out signal, real-time monitoring of biomarkers in deep tissues could be achieved, advancing detection technology for deep-tissue biomarkers.Read moreRead less
A new chemotherapeutic target from Leishmania SPP. Understanding and inhibiting CYP61LD, a sterol C22 desaturase. Leishamniasis is a debilitating and often fatal disease that is caused by a parasite, Leishmania sp., which is increasing its range to include Australia. This project aims to explore possible chemotherapeutics for the disease which inhibit a particular and unique enzyme the organism uses to synthesise the sterols it requires to live.

Visualising the structure of biological macromolecules such as proteins and other subcellular components is critical to understand the fundamentals of life. The integration of the Gatan K3 high-throughput camera system with one of the most advanced cryo-electron microscopy facilities in Australia and the Southern Hemisphere will transform the capacity of Australian researchers to study the world around us at the molecular detail needed to advance innovative research. The addition of this equipment to the University of Wollongong's research facility Molecular Horizons will result in a step change in the areas of bionanotechnology, advanced manufacturing, diagnostics, and many other areas at the interface of biology, chemistry and physics.Read moreRead less
How filopodia connect macrophages to the outside world. Fundamental to life is the ability of cells to sense their surroundings and respond accordingly. This project aims to generate a biological understanding of how certain immune cells carry out such processes, thus enabling them to combat infections.
Uncovering New Mechanisms of Metabolite-Sensing and Signaling. This project aims to understand how cells sense changes in metabolic activity, to ensure energy demands are matched with nutrient supply. Our proposal will fill critical gaps in our understanding of the molecular mechanisms underlying metabolic sensing.

This project aims to understand how cells sense changes in metabolic activity, to ensure energy demands are matched with nutrient supply. Our proposal will fill critical gaps in our understanding of the molecular mechanisms underlying metabolic sensing. This will generate new knowledge with far reaching potential for Australian industries that rely on the propagation and utilization of living organisms, including agriculture, biotechnology and brewing, as well as knowledge relevant to sporting performance and the metabolic dimensions of ageing. This project will support advanced training of early career researchers and PhD students, which will expand Australian research capabilities and contribute to a producing a highly skilled workforce.Read moreRead less
A molecular timer for inflammation and cell death. This project aims to improve our understanding of the timely function of the immune system. Most processes fundamental to life rely on the timely execution of cellular functions. One biological system in which timing is paramount is the immune system. Organismal health relies upon this front-line defence system for rapidly detecting invading microbes and inducing an appropriate, and timely, antimicrobial response to clear infection. We do not cu ....A molecular timer for inflammation and cell death. This project aims to improve our understanding of the timely function of the immune system. Most processes fundamental to life rely on the timely execution of cellular functions. One biological system in which timing is paramount is the immune system. Organismal health relies upon this front-line defence system for rapidly detecting invading microbes and inducing an appropriate, and timely, antimicrobial response to clear infection. We do not currently understand how immune responses are temporally coordinated. This proposal aims to address this key knowledge gap by characterising a novel molecular timer that dictates the co-ordinated timing of immune responses and immune cell death. These studies may yield fundamental insight into mammalian anti-microbial mechanisms.Read moreRead less
Understanding sub-cellular systems at the atomic level. By extending the range of biomolecular systems that can be modelled computationally at the atomic level the project will enable important biomedical processes such as how bacterial toxins penetrate cell membranes and how protein hormones transmit signals into cells to be understood in unprecedented detail.

This Project aims to understand the formation of the neural tube; a fundamental tissue structure that generates the brain and the spinal cord. Using interdisciplinary approaches and exploiting recent advances in transgenic and imaging technologies, the Project expects to reveal the complex interplay of molecular, cellular and mechanical processes that direct neural tissue formation and cell fate specification. Outcomes from the Project include knowledge of previously intractable developmental processes, training of future scientists and development of international collaborations. This should provide enhanced imaging capacity, a higher quality scientific workforce and position Australia at the forefront of developmental biology.

Development and validation of virtual epithelial cancer models using an integrated modelling and experimental three-dimensional approach. The mathematical and experimental modelling of the human prostate and ovary applying quantitative bioengineering concepts will lead to virtual cancer models. This project aims to validate these multi-scale models to delineate biological and pathological avenues in healthy and disease tissue and improve prevention and treatment of prostate and ovarian cancer.
