A humanised sensory neuron high-throughput screening platform . Sensory neurons are responsible for converting external stimuli such as touch or temperature into graded electrical signals that allow us to interact with the world around us. However, unlike other cell types, sensory neurons cannot proliferate and thus must be removed from human cadavers, or animals, in order to study their pharmacology and function. This limits our ability to understand neuronal signalling pathways. This project a ....A humanised sensory neuron high-throughput screening platform . Sensory neurons are responsible for converting external stimuli such as touch or temperature into graded electrical signals that allow us to interact with the world around us. However, unlike other cell types, sensory neurons cannot proliferate and thus must be removed from human cadavers, or animals, in order to study their pharmacology and function. This limits our ability to understand neuronal signalling pathways. This project aims to use sensory neurons derived from human stem cells to develop and optimise assays that can be used to study the pharmacology and function of human sensory neurons in vitro. This enhances access to critical model systems and technology platforms and removes the need for isolation of cells from cadavers. Read moreRead less
Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. ....Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. It will also develop new 3D models to simulate conditions in the human body for more rapid testing of electrodes. The new knowledge generated will improve the accuracy of predictions of platinum dissolution, develop new approaches for minimising dissolution, and contribute to reducing need for animal experimentation.Read moreRead less
Developing macrophage-based technologies for tissue regeneration. Different tissues show distinct regenerative capacities with an organism and across the phylogeny. What underlies this diversity in regenerative ability at cellular and molecular level is far from clear. Building on foundational discoveries in zebrafish, this study seeks to determine if this capacity could, in part, be explained through the properties of a component of the innate immune system, the macrophage, which preliminary da ....Developing macrophage-based technologies for tissue regeneration. Different tissues show distinct regenerative capacities with an organism and across the phylogeny. What underlies this diversity in regenerative ability at cellular and molecular level is far from clear. Building on foundational discoveries in zebrafish, this study seeks to determine if this capacity could, in part, be explained through the properties of a component of the innate immune system, the macrophage, which preliminary data shows generates a transient pro-regenerative muscle stem cell niche in zebrafish. This study will determine if macrophage subtypes acts to coordinate regeneration in other tissues and systems and if a programable pro-regenerative cell can be made in vitro that stimulate regeneration in different settings.Read moreRead less
Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occu ....Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occur naturally via various microbial means and from insects, like Galleria mellonella larvae. The overall aim of this research project is to understand plastic biodegradation and translate nature’s solutions into flexible and efficient synthetic enzyme technologies that can sustainably recycle commonly used PU foams.
