I lead a research team that is internationally recognised for its excellence in pursuing novel research questions using cutting-edge brain stimulation techniques to examine the neurophysiology of human movement throughout the lifespan. My research attracts Category 1 funding, is regularly published in the top journals in the field, and is highly cited internationally. I have a strong record of successful research supervision and training, which includes mentoring externally funded research fellows, graduating numerous PhD students, and regularly supporting honours and undergraduate placements in the laboratory. I am a highly effective teacher with a strong record of education delivery and leadership, where I shape current educational practices in several disciplines, and contribute to high-level program mapping and curriculum design. I also hold numerous senior administration and leadership roles within the University and international research community, including Discipline Lead in Physiology, School Postgraduate coordinator, President of the Australasian Brain Stimulation Society, and hold senior editorial board responsibilities for 3 leading journals in Neuroscience, Physiology and Exercise Science fields.

NEUROPHYSIOLOGY OF HUMAN MOVEMENT GROUP

I am an experienced neurophysiologist and Director of the Neurophysiology of Human Movement group. Research within this group focuses on the neural mechanisms responsible for changes in human movement throughout the life span. We specialise in the use of brain stimulation techniques to painlessly and non-invasively measure and modify the brain’s control of skeletal muscles under diverse conditions, such as ageing, exercise, training, fatigue and mild traumatic brain injury. The overall goal is to understand how the healthy nervous system functions to control movements in different situations, and how it may adapt in conditions involving neurological or neuromuscular injury.

AVAILABLE PROJECTS

Project 1

Title: BRAIN OSCILLATIONS AND HUMAN MOVEMENT

Description: Motor areas of the brain oscillate when we move, with different oscillations responsible for different aspects of behaviour. Oscillations in the gamma band (30-90 Hz) play a key role in brain plasticity and motor learning that are thought to be driven by inhibitory circuits. This study will use non-invasive brain stimulation techniques to explore the physiological basis and functional significance of this intriguing brain rhythm, and investigate in new ways how it can be manipulated to improve motor behaviour and learning.

Projects available for: Honours and HDR

Location: Helen Mayo Building (Frome Rd)

Research project start: Semester 1 and 2

Special Requirements: None.

 

Project 2

Title: BRAIN PLASTICITY AND MOTOR FUNCTION IN OLDER ADULTS

Description: Recent studies from our group show that specific brain circuits important for motor system plasticity are altered in older adults. Do changes in these circuits contribute to impaired motor performance and learning in older adults? Can we modify plasticity and learning by strengthening these circuits in older adults? Several studies using brain stimulation and electroencephalography (EEG) in human participants are planned to address these research questions.

Projects available for: Honours and HDR

Location: Helen Mayo Building (Frome Rd)

Research project start: Semester 1 and 2

Special Requirements: None.

 

Project 3

Title: NEUROPHYSIOLOGY OF EXERCISE

Description: It is now well accepted that physical activity and exercise is capable of providing benefits to the central nervous system (CNS) that can maintain or enhance brain and motor function. However, it is not known whether different features of the exercise (intensity, duration, type) influence brain function (excitability, connectivity, plasticity), or whether this can be harnessed to improve motor function. Several studies using brain stimulation, electroencephalography (EEG) and motor skill learning will be performed to examine the neural mechanisms that influence brain and motor function with different types of exercise in humans.

Projects available for: Honours and HDR

Location: Helen Mayo Building (Frome Rd)

Research project start: Semester 1 and 2

Special Requirements: None.

 

Project 4

Title: IMPROVING MOTOR SKILL LEARNING IN HUMANS

Description: The ability to learn new motor skills is a fundamental requirement for participation in modern society, but this ability often deteriorates with neurological injury. Many factors are known to influence motor skill learning even in healthy individuals, such as practice structure, fatigue, handedness, exercise, gender and advancing age. The aim of this project is to explore one or more of these factors in an effort to understand the parameters that produce the optimum conditions for improved motor skill learning in humans.

I have developed and transformed a wide variety of courses in Health Sciences (BHMS), Medicine (MBBS/BMD) and Dentistry (BDS). Recent teaching includes significant contributions to Physiology 2A (200-330 BHMS students, 2014-current), Neuromotor Control (65-130 BHMS students, 2014-current), Dental Science and Practice I and II (~80 BDS students, 2008-current), Foundations of Medicine (~170 MBBS/BMD students), and Medical Studies 2A (~165 MBBS/BMD students). My physiology teaching is internationally recognised in Dentistry by an appointment as a Physiology Examiner for the Royal Australasian College of Dental Surgeons (RACDS). I also make contributions at a Program level through my role as an Academic Transition Panel member/Program Champion for Health (Human Performance) and Course Designer in the Health Tranche for the new Adelaide University.
