个人简介

I am an NHMRC Senior Research Fellow at Neuroscience Research Australia and an Associate Professor through the School of Medical Sciences. My research area is the control of human movement. My work investigates how the brain and nervous system control the actions of the muscles. The control of muscles by the nervous system underlies all of our actions. This control requires constant modulation of the output from the motor areas of the brain to produce voluntary movements plus feedback from sensory receptors in the limbs to allow adaptation to changing conditions. My particular interest is how the motor pathways of the nervous system change with sustained or repeated activity. This includes the contribution of the nervous system to muscle fatigue and the control of movement during muscle fatigue. Our work has identified that from one-quarter up to two-thirds of fatigue in different tasks can result from fatigue in the nervous system. Repetition of motor tasks can also lead to improvements in performance. Here we are investigating whether mechanisms in the spinal cord contribute to improvement in motor performance with practice. In addition, some of my work investigates the sense of proprioception. That is, the perceptions of limb posture and movement and of muscle force.
