Mapping sites of visceral convergence connecting the colon and bladder. This project aims to develop multiple neuroanatomical approaches to identify where in the central nervous system the sensory signalling from the colon and bladder merge. The combination of such technologies is novel to the study of the central circuits relaying colon/bladder convergence into the brain and will generate new and detailed knowledge of the central pathways in which pelvic organ sensory (discomfort) and motor (de ....Mapping sites of visceral convergence connecting the colon and bladder. This project aims to develop multiple neuroanatomical approaches to identify where in the central nervous system the sensory signalling from the colon and bladder merge. The combination of such technologies is novel to the study of the central circuits relaying colon/bladder convergence into the brain and will generate new and detailed knowledge of the central pathways in which pelvic organ sensory (discomfort) and motor (defecation/urination) functions are coordinated. The expected outcomes are predicted to aid future discovery of mechanisms of cross-organ sensitisation and are anticipated to provide significant benefit to therapy development for chronic visceral pain syndromes associated with bowel and bladder dysfunction.Read moreRead less
The jugular vagal sensory connectome regulating visceral function. Internal body organs have a rich supply of sensory nerve fibres that serve important roles in monitoring the local environment for normal and abnormal sensory stimuli. These nerve fibres have different origins and wire into brain circuits that regulate widely diverse physiological responses. In this study we aim to study the neural circuits and responses mediated by a group of these sensory nerves which has not been investigated ....The jugular vagal sensory connectome regulating visceral function. Internal body organs have a rich supply of sensory nerve fibres that serve important roles in monitoring the local environment for normal and abnormal sensory stimuli. These nerve fibres have different origins and wire into brain circuits that regulate widely diverse physiological responses. In this study we aim to study the neural circuits and responses mediated by a group of these sensory nerves which has not been investigated appreciably in the past. We believe that these sensory neural circuits will reveal important new insights into how internal organs perform their diverse and essential functions to sustain life.Read moreRead less

Summary
New insights into how the brain interprets visceral and somatic sensations. Sensory nerve fibres monitor normal and abnormal stimuli in our body tissues, sending this information to the brain. I study the sensory pathways of the respiratory system which protect the lungs from harmful stimuli, such as inhaled pollutants or smoke. I discovered that respiratory sensory pathways interact with sensory circuits in the brain arising from other body tissues. The goal of this project is to investigate on ....New insights into how the brain interprets visceral and somatic sensations. Sensory nerve fibres monitor normal and abnormal stimuli in our body tissues, sending this information to the brain. I study the sensory pathways of the respiratory system which protect the lungs from harmful stimuli, such as inhaled pollutants or smoke. I discovered that respiratory sensory pathways interact with sensory circuits in the brain arising from other body tissues. The goal of this project is to investigate one example of this interaction; the convergence of visceral and somatic sensory pathways onto a brain circuit that regulates the intensity of the sensations that are experienced. This project addresses the fundamental question of how the brain processes two competing noxious sensations.Read moreRead less
Insect-inspired flapping wing robots: autonomous flight control systems. This project aims to design a novel control scheme for insect-inspired, flapping-wing, micro aerial vehicles. This type of micro aerial vehicle has complex, periodic, time-varying and inherently unstable dynamics, which are practically challenging to model and implement in hardware. This project will design energy-based automatic stabilization and task-dependent control, and develop the insect-inspired platform for testing ....Insect-inspired flapping wing robots: autonomous flight control systems.

Genes underlying enteric neuron subtype differentiation. This project aims to use new RNA-sequencing technology to identify genes important for differentiation of several major enteric neuron subtypes. Proper development and function of the digestive tract is crucial for good health. Gastrointestinal function relies on the co-ordinated activity of neural circuits in the enteric nervous system.

This project aims to use new RNA-sequencing technology to identify genes important for differentiation of several major enteric neuron subtypes. Proper development and function of the digestive tract is crucial for good health. Gastrointestinal function relies on the co-ordinated activity of neural circuits in the enteric nervous system. This project will advance Australia's knowledge base and research capabilities in the field basic developmental neuroscience, by innovative use of Next Generation RNA-sequencing technology to investigate enteric neuron subtype differentiation. The project outcomes include the generation of neuron subtype specific progenitors from naïve stem cells, which will in the longer term have significant health benefits, as gastrointestinal dysfunction is a large health and economic burden in Australia.Read moreRead less
Understanding multiday cycles underpinning human physiology. We recently discovered long-term rhythms modulating activities of our brains and hearts ranging in duration from 3-60 days. The cause of these longer, ‘multiday cycles’ remain unknown. This project aims to understand; causes of multiday cycles (measuring the nervous and autonomic nervous system), their effects (on cognition, sleep, and stress), and quantify the relationship between coupled cyclical systems.
