Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance.

We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated to others and would provide the basis for educational material and methods that would improve operator skill, safety, and performance. These individual improvements would provide overall benefits such as improved transport efficiency, reduced accident rates, saved lives and a reduction in related social costs.Read moreRead less
Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction ....Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction of two persons performing speech-hand gestures will be examined. Results will clarify how brain asymmetry affects gestural coordination in stutterers, how stuttering can be treated, and the hypothesis that speech and language evolved from a communication system based on hand gestures.

Developmental trajectory of tongue control for speech with real-time MRI. This project aims to evaluate the developmental trajectory of tongue control during speech, relating dynamic 3D vocal tract modelling to the acoustic signal. By optimising real-time MRI technology to capture and model articulatory movements, the project expects to accelerate understanding of how tongue control for speech is developed, mastered, and perturbed by factors such as rapid growth and foreign accent. Expected outc ....Developmental trajectory of tongue control for speech with real-time MRI. This project aims to evaluate the developmental trajectory of tongue control during speech, relating dynamic 3D vocal tract modelling to the acoustic signal. By optimising real-time MRI technology to capture and model articulatory movements, the project expects to accelerate understanding of how tongue control for speech is developed, mastered, and perturbed by factors such as rapid growth and foreign accent. Expected outcome is a new understanding of how different speakers' vocal tracts change and how speech is reshaped, informed by real physiological data. Significant benefits will be realised through refined methods and theory development for diverse fields e.g. linguistics, speech science, and automatic speech recognition/synthesis.

Interlimb coordination dynamics in stroke. Everyday we use our limbs in a coordinated manner. However, for a person who has suffered a stroke resulting in weakness on one side of the body even the simplest interlimb coordination tasks are difficult to perform. This project will examine interlimb coordination in persons who have suffered a stroke and explore whether the coupling between limbs can be exploited to promote fuctional recovery of an impaired limb. In particular, the research seeks to ....Interlimb coordination dynamics in stroke. Everyday we use our limbs in a coordinated manner. However, for a person who has suffered a stroke resulting in weakness on one side of the body even the simplest interlimb coordination tasks are difficult to perform. This project will examine interlimb coordination in persons who have suffered a stroke and explore whether the coupling between limbs can be exploited to promote fuctional recovery of an impaired limb. In particular, the research seeks to identify the critical components underlying the effectiveness of an intervention involving the pratice of actions bilaterally and simultaneously.Read moreRead less
Neuromuscular adaptations to training, cross training and passive physical interventions: A neurophysiological approach to understanding human performance and musculoskeletal injury. The expected national benefit arising from this research is three fold: (i) developing knowledge of approaches taken to improve exercise performance across the spectrum of novice to elite levels of participation, (ii) improved understanding of the physiological basis for widely applied interventions used to facilita ....Neuromuscular adaptations to training, cross training and passive physical interventions: A neurophysiological approach to understanding human performance and musculoskeletal injury. The expected national benefit arising from this research is three fold: (i) developing knowledge of approaches taken to improve exercise performance across the spectrum of novice to elite levels of participation, (ii) improved understanding of the physiological basis for widely applied interventions used to facilitate exercise, performance, as well as injury prevention and rehabilitation, and (iii) increasing the pool of world-class researchers who will make a substantial difference to the health and wellbeing of the community through one post-doctoral and two doctoral programs. This project will cement existing tertiary-industry sector collaboration, which will ensure long-standing benefits to the community.Read moreRead less
Dynamics of Locomotion: Visualisation in skill acquisition & rehabilitation. How does visual information and attention determine the control and coordination of locomotion? Using large-screen projection of computer graphics and immersive virtual reality, we will examine the influence of visual information on driver training, gait in the elderly, cardiorespiratory control, and the attentional interference of mobile phones on driving.

How does visual information and attention determine the control and coordination of locomotion? Using large-screen projection of computer graphics and immersive virtual reality, we will examine the influence of visual information on driver training, gait in the elderly, cardiorespiratory control, and the attentional interference of mobile phones on driving. Experiments will be based on principles from dynamical and complex systems theory and will inform the design of innovative algorithms for autonomous mobile robots. Expected outcomes include improved road safety, new methods for the rehabilitation of those with gait disorders, and a deeper understanding of the physiological response to virtual exercise.Read moreRead less
I am a neurophysiologist who examines the neural control of movement and the interaction of sensation and movement in human subjects. I study cortical and motoneuronal events during exercise and muscle fatigue, how cortical connections to the motoneurones change with practice of motor tasks, and whether they can be changed artificially. I also study proprioception i.e. the sensations related to relative position and movement of parts of the body and the production of muscle force.
Unravelling The Neural Bases Of The Diverse Capability Of The Grasping Hand

Summary
This project aims to unravel how the brain guides the hand to interact with objects in diverse ways, a topic that is poorly understood. We will use fMRI to find active brain areas during object grasps, & then use non-invasive brain stimulation to briefly “shut off” some of these areas, & then identify changes in grasping & previously active brain areas. Insight from this project on the neural bases of diverse hand-object interactions will speed up important work aimed at improving hand function.
A new model of human speech production through computational modeling and human functional brain imaging. It is still largely a mystery how we convert our thoughts into fluent intelligible speech. This project will bring together experts in speech pathology, neuroscience, and computer modeling to create a new biologically-plausible model of speech production to advance understanding of speech development, ageing, and mechanisms of recovery after injury.
